• Purpose 4: to output to an external monitor or other device like LiveU for streaming. Ultra now supports 1080p 50 & 60 fps UVC out. Currently can't support 4K and other frame rates. For connection issues, please see Q3.

PS: If the Ultra suddenly shuts down when connected via USB-C, please don't panic. This is likely due to an issue with the cable, causing the camera to recognize the Ultra as a power bank, which leads to the shutdown. Simply switch to a fully functional USB-C to USB-C cable.

A3: If you want something highly portable and completely independent of a computer, the YoloBox Ultra is an all-in-one system — encoder, monitor, recorder, and switcher. No computer is required. However, if you prefer, you can also use it with a computer. The Ultra works seamlessly with OBS, vMix, Zoom, Teams, and Google Meet.

To output from a computer to the Ultra (HDMI out):

• Mac: Use a USB-C hub and an HDMI cable. Make sure the HDMI cable is connected to the Ultra's HDMI input.
• Windows: It depends on your computer's port. If your Windows device has an HDMI output, simply connect it to the Ultra's HDMI input. If it uses USB-C, you'll need a USB hub and an HDMI cable.

To output from Ultra to a computer (HDMI out):

• Mac: Use a USB-C hub, an HDMI capture card, and an HDMI cable. Make sure the HDMI cable is connected to the Ultra's HDMI input.
• Windows: It depends on your computer's port. If your Windows device has a USB-A port, simply connect it to the HDMI capture card and Ultra's HDMI output. If it uses USB-C, you'll need a USB hub and an HDMI cable.

To output from Ultra to a computer (UVC out):

• Mac: Use the USB-A to C that came with the Ultra. Remember to enable the USB-C out on the Ultra first. Also, you might need a USB-C hub because most Mac computers don't have a USB-A port. For more details, you can also check Q33.
• Windows: Use the USB-A to C that came with the Ultra. Remember to enable the USB-C out on the Ultra first.

The YoloBox has a built-in fan for cooling and generally does not overheat. However, if you are in a very hot area or using the YoloBox outdoors in direct sunlight, there is a risk of overheating. Overheating can cause the machine to freeze, live streaming to lag, and data loss. It is advisable to ensure proper cooling. Similarly, if you use it excessively and the CPU usage is too high, it may also lead to overheating. It is recommended to reduce the usage of certain functions to some extent.

First, you need to ensure that the charger and charging cable you are using are correct. We recommend using the charger and USB-C to C cable that came with the Ultra. Do not use a USB-A to C cable, as it is meant for data transfer. Besides the included charger, the YoloBox Ultra can also use chargers greater than 45W; you can use PD chargers.

PS: If your Ultra keeps flashing the YoloLiv logo, it's likely due to an incompatible charger or insufficient charging. We suggest using the correct charger, allowing it to charge for 2–3 hours without interruption, and then pressing and holding the power button to turn it on.

YoloBox Ultra has an HDMI output and a USB-C UVC output. HDMI OUT is assignable — it can output Mirror, Program, or Multiview. You can choose it yourself in the settings. Note that for USB-C output, you need to enable USB-C out in the settings. If you find that USB-C out is not working, check if the cable you are using has issues.

Generally, we recommend using the USB-A to C cable that came with the Ultra. If you're using a MacBook, you can use a USB hub for the connection. Alternatively, you can try using a fully functional USB-C to C cable.

The YoloBox has three audio input ports: line in, mic in, and USB.

• Generally, the line in can connect to audio mixers, wireless mics, etc., such as Rodecaster, Zoom, Rode/Hollyland/DJI wireless mics.
• The mic in is typically for connecting microphones, like Shure or Rode mics.
• The USB can also be used to connect audio mixers.

The YoloBox also has a headphones port for wired headphone monitoring, compatible with both TRS and TRRS.

PS: You can also connect AirPods via Bluetooth for monitoring, but this only allows for audio monitoring and does not input audio.

We generally recommend that you upgrade, as the firmware not only includes many new features but also fixes bugs from previous versions.

How to update the firmware: You need to go to the 'Account & Settings' page, find the version, and click the update icon to upgrade. If you're not sure when you'll receive version updates, feel free to join our official Facebook group, where notifications are posted with each update. Alternatively, you can check the Ultra's version history blog.

However, if you feel that your current version is working well and stable, and you have no intention of using new features, you can choose not to upgrade.

We recommend performing a factory reset in the following two situations:

If You Encounter Sudden Bugs: If your YoloBox starts showing glitches or bugs that weren't there before, a factory reset can be a quick fix. Sometimes, these issues may arise from corrupted data or misconfigurations that occurred over time.

After a Firmware Update: If you've recently updated your YoloBox's firmware, it's a good idea to perform a factory reset afterward. Resetting ensures the update clears any leftover data from the previous version, helping your device run smoothly with the new firmware.

Important — Don't Reset After a Software Update! If the update you installed is a software update, do not perform a factory reset. Doing so will undo the software update, and you'll have to reinstall it. You can only perform a factory reset after firmware updates, not software updates.

Of course. The Ultra has PTZ control functionality and can connect to PTZ cameras. Compatible PTZ cameras include Obsbot, Sony, PTZOptics, Feelworld, Logitech, and others.

First, connect your PTZ camera to the Ultra. Then create a live event and click to enter it. In the gear icon above the video source, you'll find the PTZ control. Click on it, and then an IP address pop-up will appear that you need to fill in. Note that you need to make sure your Ultra and camera are on the same network for the connection to work successfully.

For more tutorial details, please check out: PTZ Control & Customized Layout on YoloBox Ultra V 2.5.0

• YoloBox Extreme is the only model that doesn't need to activate the NDI.
• Ultra and Pro need to purchase the NDI license.

NDI stands for Network Device Interface, a free protocol that allows video and audio to be transmitted over a network. NDI is used in video production, streaming, and other applications. You can transmit wirelessly using Wi-Fi or via a wired connection using Ethernet. Generally, wireless transmission using NDI is more common, and if your streaming scenario heavily relies on wireless transmission, you should consider using NDI.

To enable NDI licensing for YoloBox, a payment of $99 is required. You can choose to purchase it through Shopify or via PayPal/bank transfer. After making the payment, you need to email contact@yololiv.com with your YoloBox's serial number and a screenshot of the payment. We will activate NDI for you within one business day. Note that this NDI license is only for the YoloBox side. Your camera will also need an NDI license, which you need to acquire from the camera manufacturer's support; we cannot assist with that.

See also: Activating NDI on YoloBox Ultra: A Step-by-Step Guide

PS: If your device is the Ultra, you can connect up to 3 NDI cameras. If your device is the Extreme, you can connect up to 6. If your device is the Pro, you can connect 1. YoloBox supports Full NDI / NDI HX / HX2 / HX3, but not all are Full NDI.

If you are unable to connect to the desired NDI camera, first check if all devices are on the same network. You may also consider switching the Wi-Fi to 5 GHz or using H.265 and then try again.

VFA is Video Follows Audio. It automatically switches your video feed to the camera that is currently capturing the active audio source. In other words, it lets your video content "follow" the audio being picked up by your cameras or audio input.

This is particularly useful when managing multiple cameras in a live environment. If you're doing a podcast stream, it can greatly reduce the chaos of manual camera switching.

The VFA feature is ideal for many kinds of streaming. This includes podcasters, event streamers, and live shows & discussions.

For more information and tutorials, please check out these videos:

• How to Use VFA (Video Follows Audio) for Auto Switching Video Sources on YoloBox Ultra
• Auto-Switch Comparison: RØDECaster Video vs YoloBox Ultra

SD Card Compatibility: The YoloBox Ultra supports SD cards formatted with FAT32 (128GB), exFAT (256GB), and NTFS (256GB).

Media Format Compatibility: When facing difficulties with video or image recognition on your YoloBox, ensure that your files are in the correct formats. Here are the supported formats for various media types:

• Image Formats: JPEG, PNG, GIF
• Video Formats: MP4, MKV, MOV (without alpha channel), MPG, VOB

Remember, YoloBox does not support AVI or WMV (Windows Movie) formats.

If everything above is correct but the SD card still doesn't display, here are a few methods to try:

1. Plug and unplug the SD card.
2. Reformat the SD card.
3. Reboot the YoloBox.
4. Perform a factory reset.

YoloBox supports most SIM cards. First, ensure that your card can make calls and has data. If your phone cannot be used normally, YoloBox will also not function.

If the SIM card is recognized and there's a triangle icon in the top right corner but you can't access the internet, try the following: Find the APN information for the SIM card and change the APN on YoloBox to match it exactly. You can refer to the SIM Card Troubleshooting Tips blog for detailed steps.

Additionally, consider the following possibilities:

1. Is the SIM card bound to a phone? If it is, it cannot be used in other devices.
2. Does the SIM card have a PIN?
3. Try to provide the device's IMEI number to your local carrier for TAC code registration (the first 8 digits of the IMEI).

The YoloBox Pro, Mini, or Original versions are region-specific: NA is for North America, EM is for Europe. If you purchase the wrong region, the SIM card may not work correctly. The YoloBox Ultra does not have this issue, as it is a global version.

YoloCast and YoloBox can be separate, but they can also be interdependent. YoloBox is a hardware live stream device, while YoloCast is a cloud-based video platform that allows users to live stream.

If you already have a YoloBox, whether you need to purchase a YoloCast package depends on the features and services you desire. If you want to use the additional functionalities provided by YoloCast like Network Bonding, then purchasing the package is necessary. If not, you don't need to pay for YoloCast.

Also, YoloCast has free functions like add platforms, YoloCast overlays. These functions can be used with YoloBox without paying any subscription.

If you have any questions about YoloCast, feel free to contact hazelhe@yololiv.com.

Serial number is the 'identity card' for each product. We use the serial number to identify each YoloBox, which is essential for activating NDI, network bonding, YoloCast packages, and checking logs.

You can find the serial number in 'Account & Settings' under 'About Device.' Click on it to view the serial number.

Upload the logs: Navigate to the "Account & Setting" section on your YoloBox and click on the Diagnostic Logs option. The uploading process may take some time to complete.

Sometimes, technical support may ask you to provide logs and the serial number to help the team diagnose the issue. When providing the logs, it's best to also mention the specific time the problem occurred.

Currently, if you want to reuse your previous settings, you can choose to use the duplicate feature. Go back to the standard events interface, click on the three-dot icon in the upper right corner of previous events, and you will see the duplicate function.

Currently, the duplicate feature does not allow all settings to be copied, but most basic settings are retained. However, please note that if there were any bugs in your previous settings that have been fixed in later updates, those may not be copied.

Yes. It's a free service. No subscription needed.

How to use Multicasting function:

1. First, create a live event and enter it.
2. Second, go to setting bar and find 'streaming mode'.
3. Third, select 'using the multistreaming service'.

Adding an account can be done in several ways, but we recommend using YoloCast to add your account.

1) From YoloCast:

• Log in to YoloCast from your computer or phone using your YoloLiv account.
• Find 'Destination' and click 'Add Platform'.
• Select the platform you want to link and agree to the terms and conditions.

2) From YoloBox:

• Click the '+' icon and select the platform you want to link.
• Click 'Add Account' and log in on Ultra.
• Enter your account details and agree to the terms and conditions.

For more details, you can check out this blog: How to Link & Delete Accounts to YoloBox (YouTube/Facebook/Twitch/RTMP).

Yes, you can definitely adjust the streaming settings.

YoloBox can adjust the streaming resolution. For example, Ultra supports 4K, 1080P, 720P, 480P. Go to setting bar — you can find 'stream encoding setting'. You can choose CBR, CQ, or VBR.

• CBR maintains a fixed bitrate throughout the video. It is recommended for live streaming and video conferencing.
• CQ aims to maintain a consistent level of quality across different bitrates. Prioritizes a stable quality level across varying bitrates.
• VBR adjusts the bitrate based on the complexity of each scene.

There are also other options to adjust, like Bitrate, FPS, and H.264/H.265. Please note that not all platforms accept H.265.

YoloBox supports streaming/recording/live streaming & recording at the same time. The Ultra model even supports ISO recording.

What is ISO recording? It is a technique that allows users to record audio and video from multiple sources simultaneously. This can be useful for editing, as it allows users to record multiple angles without having to set up the camera multiple times.

YoloBox Ultra supports a variety of resolutions for recording: 720p, 1080p, 2K, and 4K. You can also choose the recording source — whether it's from the program, HDMI, USB webcam, NDI, or SRT video sources, you can record from any of these. Frame rate options typically range from 20 fps to 60 fps, like 24fps, 25fps, 30fps, 48fps, 50fps, 60fps. YoloBox Ultra supports H.264 and H.265 compression.

Here's something important to note: Ultra's ISO recording also has performance limitations. This brings us to the overall performance limits of the Ultra.

The Ultra's encoding performance maxes out at 1080p 220fps. Streaming, recording, replay, and NDI output all consume encoding performance. Remember, 1 × 4K is equivalent to 4 × 1080p.

Now, what does that mean? Well, it means that if you're live streaming in 4K at 30fps, it's essentially like streaming at 1080p 120fps in terms of the system's encoding load. This means you will only have 100fps left for recording video. If you're using the 1080p 30fps, you can still choose up to 3 channels. If you want to do 4K recording while streaming, adjust your recording settings to 4K 24fps. But this only supports 1 channel.

For more details, please check out: Top Tips to Optimize YoloBox ISO Recording.

For YoloBox Extreme performance limitation, please check: Test Result — YoloBox Extreme's Max Encoding & Decoding (CPU & GPU Performance).

The YoloBox series generally supports replay, except for the original model. The Ultra not only supports replay but also Multicam replay. No extra fees, no complicated software needed.

On the toolbar, find the replay icon. You can select your desired video source for the replay. This could be from your live program feed, any of the HDMI inputs, USB webcams, or even NDI/SRT sources.

You can adjust the duration of your replay clip according to the moment you want to capture. Simply click it and choose the duration you want. You can also control the speed of the replay. Slow it down for dramatic effect or speed it up for a quicker recap. Also, you can tweak the audio of your replay. You have options here: mute the replay audio to focus purely on visuals, or adjust the volume to blend seamlessly with your live.

The YoloBox Ultra currently supports replay recording in two high-definition resolutions: 720p and 1080p. It also allows you to choose 20 fps to 60 fps for replay.

It has two modes for replay, 'Always Play Now' and 'Always Use Later'. Choosing 'Always Play Now' immediately starts the replay during your live stream. 'Always Use Later' saves the replay for future use, perfect for creating highlights or post-event edits. And 'Always Ask' gives you a prompt each time, letting you decide on the fly whether to play or save the replay.

You can also personalize your replays with logos, intros, and outros, making your content stand out even more. Select 'Replay Logo', and choose a file from your SD card. You can size and position this logo anywhere on the screen. You can also add custom intros and outros to your replays. Please note that currently it doesn't support alpha channel videos. There's one more tool — adding transitions to your intros and outros.

For more details, please check out: Level Up Your Sports Live Streams with Multicam Replay on YoloBox Ultra.

The most important thing about audio mixer is to be sure to enable the "ON" button for each audio channel. Otherwise, the audio channel will be off, and you won't hear any sound. Then, let's talk about the audio mixer in detail.

The audio mixer has features like volume control, AFV, Mix Minus, and Audio Delay.

In the current version, volume bars now distinguish between left and right channels, with the main volume's specific decibel level clearly displayed on the right side of the bars. We've added color changes to indicate different volume ranges, and we've introduced vertical lines and precise volume scales to visually represent the strength of the audio signal.

There's now a scale on the slider bar to show volume levels, and the exact volume value is displayed next to the slider for more accurate adjustments. These changes make monitoring and adjusting audio more intuitive and professional, allowing users to control audio output with greater precision.

What is AFV? Audio-Follow-Video (AFV): an operational mode in which audio and video switchers are tied together so that when the operator selects the video source, the audio simultaneously and automatically switches to the same source.

How to use AFV? First, confirm the audio channels that need to participate in AFV, and then turn on the AFV buttons for those channels. After that, you won't need to operate the audio mixer anymore. You just need to switch the video sources, and the audio will follow automatically.

What is the headphone icon? This is what we refer to as Mix Minus. By turning on the headphone icon, you can monitor this audio channel; if it's turned off, you won't be able to monitor it. This feature helps prevent hearing your own echo while monitoring the live audio.

The Delay button can now be found in the top-right corner of each audio channel. Clicking this icon allows you to adjust the audio delay for each individual channel. In upcoming updates, the audio delay settings will support both positive and negative values, providing more precise control over synchronization adjustments.

Additionally, there is a slight transmission delay between the YoloBox Ultra's mixer and microphone inputs compared to the HDMI input. This often results in the audio from the camera being out of sync with the audio from the microphone or mixer. In such cases, adjusting the audio delay is necessary to achieve proper synchronization.

For more details, please check out: Everything You Need to Know About the NEW Audio Mixer in v.2.6.0.

YoloBox has many kinds of overlays, including image overlays, lower thirds, countdown timer, titles, social overlays, time overlays, video overlays, web URL overlays, YoloCast overlays.

Image overlays: can be either static images like JPGs and PNGs, or even animated GIFs. You can choose them from the SD card or hard drive.

Lower thirds: YoloBox has multiple lower thirds templates, like scrolling text. You can easily adjust the text, font, color, shape, and others.

Countdown timer: perfect for a pre-show setup. Customize the text, edit the font, size, and color of this text to make sure it stands out. You can set the specific time for your event to begin.

Web URL overlays: You can use URL overlays from UNO, Radar, StreamElements, RadarBox, H2R.graphics, Cricclubs, Singular, aaraonpk.tv and more.

YoloCast overlays: YoloCast overlays offer two options — My Overlay (from YoloCast overlay lab) and Third-Party GFX.

• My Overlay: Go to YoloCast to find the overlay lab and choose the overlay template you like. Then, adjust the settings and update. You will find it in the My Overlay section.
• Third-Party GFX: This is for third-party graphics. You can find Third-Party GFX in YoloCast overlay lab. Click and paste the URL from other platforms. Go back to YoloBox, and you will see the overlays in the Third-Party GFX section.

Video overlays: You can use the video sources in the video switch section as video overlays. You can scale and reposition the video overlays wherever you want.

The above outlines the main ways to use overlays. Instead of adding overlays one by one, you can also long-press an overlay in the overlay section to enter edit mode directly. Besides long-press editing, there are also some functional buttons. You can delete or copy overlays, and there are two buttons for adjusting the order of overlays: one moves the overlay up in the layer stack, and the other moves it back in the layer stack. The last function is the lock feature, which allows you to lock this overlay together with your video source. Note that it does not lock to the screen, but rather to a specific video source.

For more details, please check out: How to add overlays to your livestream with YoloBox.

YoloBox has multiple built-in multiview templates. Most of the operating methods are the same. Below, we will focus on a few key points.

The Multi-view menu can be seen by clicking on "Add Video Source" in the bottom right corner.

PiP: When you need to do a tutorial or game commentary, PiP Video would be the most appropriate layout. After selecting 2 video sources, you can change the shape of the sub-screen, adjust the scale of the small video frame, as well as adjust the thickness and color of the border. Swap Video can switch the sub-screen and the background screen.

Side By Side: Side by side is a commonly used layout. When you need to have a dialogue with your guest during a live stream, side by side might be the most suitable screen layout. In this layout, you can customize and display the background.

News Layout: News Layout is particularly useful when you're looking to present a structured and dynamic news content. In this layout, the large box on the left is used to display the news content, while the small box on the right carries the host's camera. You can switch the positions of the two boxes by using the swap video feature. Additionally, you can not only customize the background but also adjust the background image opacity.

Customized: It allows you to create your own multiview layouts. Enter the interface, you will see 'Add Source'. Click on it to add all the video sources available in the preview. Alternatively, you can also click the button in the top left to add video sources. The two icons at the bottom left are for adjusting the position of the video sources or images — you can choose to move the layer up or down. The first icon on the right is for adding a background — you can choose from the built-in backgrounds in the Ultra, or select an image or animated gif from the SD or SSD. Below that is the PTZ control, where you can adjust the camera angle. Finally, there's the delete function, where you can select the video source you want to remove.

Let's take a look at the functions at the bottom next. The h-flip and v-flip options are self-explanatory — they allow you to flip the video horizontally and vertically. The crop function also provides several fixed modes like 1:1, 16:9, 4:3, or you can choose free cropping. The position function includes position, scale, and ratio. You can precisely adjust the position, size, and aspect ratio of each video source. The replace function is very convenient — for example, if your layout is already designed but you want to swap out a video source, you can just click on replace to do that.

• PTZ Control & Customized Layout on YoloBox Ultra V 2.5.0

YoloDeck is the ultimate streaming controller for YoloBox. It features 15 customizable LCD keys that let you instantly trigger unlimited actions — start/end live stream, record, switch video source, add graphics, adjust audio, launch instant replay, scoreboard, and so much more.

How to connect? In the package, you'll find a USB-A to C cable. To get started, connect the USB-C end to your YoloDeck and the USB-A end to your Ultra. Alternatively, you can use a USB-C to C cable to connect YoloDeck to Ultra if you have one available.

PS: It's important to note that we recommend connecting YoloDeck before you enter the live event. This ensures that everything is set up and ready to go for a smooth streaming experience.

When you first connect YoloDeck to Ultra, you might notice that YoloDeck is black and doesn't display any icons. Don't worry, this is completely normal.

Start by creating a live event as you normally would. Once it is set up, it's time to configure YoloDeck.

Enter the events and head over to the settings section of your YoloBox. Scroll down until you find the 'YoloDeck Configuration' option.

Inside the YoloDeck Configuration menu, you'll see a few options. To initialize YoloDeck, simply click 'Save.' Once you hit 'Save,' you'll see your YoloDeck light up and display the icons, indicating that it's ready to go. If you make any changes and need to reset YoloDeck, you can easily do so by clicking the 'Reset' button within the same configuration menu. This will revert YoloDeck to its initial settings.

For more details, please check out: How to Use YoloDeck.

Click "Add Video Source" in the bottom left corner. The input port for the SRT video source is located at the bottom left of the page. The box requires you to type the SRT input URL in this format: srt://:.

How do we find the IP address and port? Before proceeding, it is necessary to check if the network your Ultra is connected to is the same as the network your OBS computer is connected to. SRT video streaming between devices can only be achieved under the condition of using the same network.

Different operating systems have different methods for finding the IP address:

• Windows 10: Open Command Prompt (Win+R → "cmd"). Type ipconfig and press Enter to find your IPv4 address. For example, it might be 192.168.30.25.
• macOS: Click the Wi-Fi icon in the top right → "Advanced…" → "TCP/IP" tab. Here you can find your IP address.
• Linux: Open Activities and type "Network" (or "Wi-Fi"). In Network settings, click the Gear icon next to the network you're connected to. Your IP address will be listed in the Network profile.

Before setting up SRT sources, you need to download OBS from its official website and then add a media source in OBS.

To send to the Ultra: go to "Settings" → "Stream", change it to service custom, and then enter the server URL in this format: srt://:?mode=listener&timeout=5000000. For instance, if your IP is 192.168.30.207, the URL would be srt://192.168.30.207:8888?mode=listener&timeout=5000000. Then click confirm.

For more details, please check out: How to Send SRT Video from OBS to YoloBox Ultra.

Here we will use OBS as an example for RTMP input.

First, come to the main interface of OBS. Click on "Settings" in the lower right corner, enter the "Stream" option, select "Custom" from the menu bar at the top. Here, we also need to provide the Server URL and Stream Key.

After the RTMP server is turned on, you need to generate an RTMP URL on the RTMP server. It looks like rtmp://192.168.20.244:1935/live/livestream. What do these characters mean?

The URL can be divided into three parts:

1. The beginning rtmp:// is fixed.
2. The second part is made up of the IP address and port. The IP address is the IP address of the network the RTMP server is connected to. You can find this in your computer's network settings.
3. The third part is the stream key, which is live/livestream.

Please note that the format of the RTMP URL is not completely fixed, and there are slight differences in the RTMP URLs provided by different RTMP servers. For example, the RTMP URL generated by GoPro does not include port information. The RTMP Input URL entered on YoloBox is based on the RTMP URL provided by the RTMP server.

After setting up this information on the RTMP server, copy and paste this information into OBS. In OBS, you need to break down the RTMP URL for input — in the server field, you only need to enter the IP address and port, which is rtmp://192.168.20.244:1935. The latter part live/livestream is filled in the Stream Key information box. Then return to the main page of OBS and click "Start Streaming".

Now, open Ultra's live operation panel. Click "Add Video Source" in the lower left corner, drop down the video source menu, and select RTMP. Enter the RTMP Input URL — the components are the URL and Stream Key we set before, written together. After all the information is entered, click "Done" in the upper right corner. Next, you can see the RTMP source in the lower left corner.

For more details, please check out: How to Use RTMP IN with YoloBox Ultra.

If HDMI is stuck on loading, you can try the following solutions:

1. Change the HDMI cable or HDMI port.
2. Adjust the camera's resolution and frame rate.
3. Update the HDMI interface.

See also: How to Resolve HDMI Issues on YoloBox Ultra.

If none of these methods work, please refer to Q17 and provide the serial number and logs to technical support.

If HDMI is not loading but showing a black screen, you can use the HDMI loop method to test if the HDMI port is faulty. See: HDMI-in-Loop Test: A Quick Way to Check HDMI Port.

For encoding settings, you can choose:

Single Setting: Live streaming, Recording (Program + Others), Replay, NDI Out, and SRT Out share the same settings.

Separate Settings: Only provides two encoding settings for use. Recording has one separate parameter, while Replay and Recording (Program + Others) share this one. Live streaming, NDI Out, and SRT Out share another.

For better stability and performance, we recommend using Single Setting with encoding reuse.

Example:

• Single Setting: If you choose Single Setting, Live streaming, Recording, Replay, NDI Out, and SRT Out will all share the same parameters. For example, if you set live streaming to 1080p 30fps at 6000kbps, then all these functions will also use 1080p 30fps at 6000kbps.
• Separate Settings: You can set parameters separately. For example: Live streaming, NDI Out, and SRT Out can share one setting, such as 1080p 60fps. Recording and Replay can share another setting, such as 4K 30fps.

YoloBox output to Mac/Windows (HDMI out):

Many YoloBox users enjoy combining it with platforms like Zoom and Microsoft Teams. Here are the steps:

Step 1: Use the correct cables. To connect the YoloBox to your Mac as an input source, you will need a USB hub. Also, you will need an HDMI capture card and a standard HDMI cable. Please note that Elgato Cam Link and YoloBox are not compatible.

Step 2: Connect YoloBox with Mac. You need to connect YoloBox to the computer via HDMI out if you want YoloBox as an input source.

Step 3: Open Zoom/OBS/Others. Once you correctly connect the YoloBox to your computer, open the software you want to use. Here's an example for OBS: Add 'Video Capture Device', and Choose 'USB video'. You will get the YoloBox interface.

Mac/Windows output to YoloBox:

First, you need a USB hub. Second, connect your YoloBox to your Mac/Windows via a standard HDMI cable. Please note that you need to connect YoloBox via HDMI in if you want YoloBox as an encoder. But some Windows computers come with an HDMI out port, allowing you to connect directly to the YoloBox's HDMI in.

Also, you can use UVC out if you want YoloBox to output to Mac/Windows:

1. Turn on the USB-C output function.
2. We recommend using the USB-A to USB-C cable that comes with YoloBox. If you're using a MacBook, you'll need a USB hub for the connection. Alternatively, you can test with a fully functional USB-C to USB-C cable.

YoloBox has many built-in scoreboard templates that can be used for various sports such as football, volleyball, basketball, ice hockey, and tennis.

In the toolbar, find 'Scoreboards,' click on the gear icon in the upper right corner, and you can choose different types of scoreboards.

The built-in scoreboards in YoloBox allow you to modify the scoreboard size, team scores, and use timers for both counting up and down. You can also set periods. Additionally, you can adjust the styling of the scoreboard, including team names, fonts, colors, and logos. The operation is very simple and user-friendly. If you want to adjust the position of the scoreboard, you can move it directly in the preview on the left.

If none of the built-in scoreboards suit your needs, you can also opt to use web graphics. YoloBox offers two types of web graphics: one is web URL, and the other is YoloCast overlays. For web URL, you can choose from many scoreboard websites, such as UNO, Cricheroes, etc. When using a web URL, you need to input the corresponding link.

Note that if the original link is too long, you can use Bitly or ShortURL to shorten it to avoid spelling errors. However, the loading speed of short links may be slightly slower.

If you choose YoloCast overlays, you can directly select your favorite styles from the YoloCast overlay lab, make modifications on the YoloCast side, and it will automatically sync to YoloBox without needing to input a link.

There are many possibilities for this issue:

1. You haven't turned on the USB-C output function.
2. You're using the wrong cable. We recommend using the USB-A to USB-C cable that comes with YoloBox. If you're using a MacBook, you'll need a USB hub for the connection. Alternatively, you can test with a fully functional USB-C to USB-C cable.
3. The USB-C port might be damaged. You can try connecting an external hard drive to see if it works. If the USB-C port can't recognize anything, it's likely that the port is damaged.

Go to 'Account & Settings', find 'Keyboard Settings'. Click it and you'll see the languages, preferences, and other settings.

• Global Servers: YoloLiv has deployed servers worldwide for stable and reliable live video transmission. Users will automatically get the network from the closest server.
• Automatic Priority: YoloLiv's technology automatically adjusts the priority of each connection for optimal performance.
• User-friendly: Getting started with network bonding is incredibly easy with YoloLiv — just a single tap is all it takes. No complicated setup is needed.

Network bonding is a paid service:

• Basic plan: 20 GB / month, for occasional live streaming — $299 / year
• Plus plan: 50 GB / month, for live streaming on a regular basis — $499 / year
• Pro plan: 100 GB / month, for broadcasters and pro streamers — $999 / year

iPhone to YoloBox Ultra: To connect your iPhone, you'll need a USB-C to HDMI adapter and an HDMI cable. Plug the USB-C end of the adapter into the YoloBox Ultra. Connect the HDMI cable between the adapter and your iPhone. Your iPhone's display will appear on the YoloBox screen.

iPad to YoloBox Ultra: For iPad users, you can use a USB-C to HDMI cable to connect them. Plug the USB-C end directly into the YoloBox Ultra, then connect the HDMI end to your iPad. Also, if you can't find the correct USB-C cable, you can use the adapter mentioned above.

iPad to YoloBox Ultra (USB): Some users asked, "All my HDMI ports on the Ultra are filled. How can I connect my iPad?" No worries, you can also connect it via the USB-A port. For the iPad, you can use an adapter to convert to HDMI or use a USB-C to HDMI cable directly. Then, use an HDMI capture card to connect to the USB port. You can connect it with a USB-A to USB-A cable, or you can use a USB-A to C cable along with a USB-C to USB-A female adapter.

Important Note: Enabling Audio. While video will display seamlessly, you won't get audio from the direct connection. So, many users can only see the camera image, but no audio.

Here's how to include audio in your stream: Download the Blackmagic Camera app on your iPhone or iPad. Go to 'Settings', and find the 'Audio Monitor' feature. Enable audio monitoring, and ensure the audio output is changed, not the Speaker. Make sure that you enable the HDMI audio channel on the YoloBox.

YoloBox supports the easiest chroma key function. First, make sure the video source has a green/blue background.

Click the top right icon of the video source, and choose Chroma Key. Enable the key switch, choose the key color type. Basically, you're done. Also, you can choose the background image from your SD card (only images and GIFs).

If you want to use a video as a background, you can use the chroma key first. Then, use PiP or customized layout to recreate.

Invite Guest allows you to invite other people to join your live stream wherever they are. They can join the live using their phone or computer through an email sent from the YoloLiv backend. You can also use this feature as a way to connect wirelessly, using your phone as a webcam.

Please note that monitor mode doesn't support invite guest function.

How to invite guest? First, find this function — it looks like a person icon. Then, type the emails and click send. Remember, only up to 5 people can be invited. Also, you need to enable 'Allow Participants to Join'. Otherwise, they can receive the emails but can't join the event. Guest's video will be displayed in the switch section, and you can use it as a normal video source for multiviews/recording/streaming and others.

How do I let it fit the screen? Now it's vertical. If you're using the phones to join the live, please unlock the orientation to make it horizontal.

Currently, there are two methods for remote control: one is app control, and the other is web control. App control is currently only available for Android phones. Web control is a web-based application, so it can be used on both computers and phones. If you are using an iPhone, you can use web control.

For the two control methods, they only support Wi-Fi and Ethernet now.

App control:

• How to download this app? Go to the YoloLiv official website to download it.
• What functions can this app control? Video sources, overlays, audio mixer, and scoreboard.

Web control:

• How to find web control? Go to YoloCast to find this.

Please note that the phone/computer and your YoloBox need to be under the same network. Then, go to the setting bar and find the mobile/web control. Fill in the IP address your YoloBox provides to connect.

Bitrate ranges and recommended values (Mbps):

Required upload speed by resolution and frame rate:

This problem often arises when your YoloBox is charging while your audio equipment is plugged into a different power source. Fortunately, there are effective ways to resolve this issue.

Use Battery-Powered Audio Equipment: One straightforward solution is to use audio equipment with its own battery power. This eliminates the dependency on external power sources, thereby reducing the chances of a ground loop.

Unify Power Sources: Try to use the same power socket for connections — this can help minimize interference. It can often equalize the ground potential and minimize the loop.

Invest in a Ground Loop Noise Isolator: A ground loop noise isolator is an affordable and efficient way to tackle this issue. Its function is to break the loop and eliminate the noise caused by ground loops. These devices are easily available and can be a simple plug-and-play solution.

See also: How to Solve the Buzzing Sound with YoloBox: Ground Loop Issue.

In this case, there are many possibilities.

First, you can connect a mouse and try to click on the screen with it. If you find that the mouse can operate, then the screen is likely broken, indicating physical damage. For specific repair or replacement, please refer to Q4.

If you find that the mouse is unresponsive, you need to consider whether there is a problem with the software system. At this point, please remember the various settings and your operations of the device when the issue occurred, and then upload the logs. Finally, contact the support email contact@yololiv.com or Josh Gately, and send the serial number of your device to request assistance from the YoloLiv technical team to troubleshoot the issue.

Basically, the reason for frame drops is poor network quality. If your network is good enough, frame drops should not occur. So, how can you determine if your network is good?

You can find 'Network Settings' in 'Account & Settings', then click on 'Network Test'. This will allow you to check your current internet speed. However, it's important to note that internet speed is not the key factor in determining live streaming speed; upload speed is what matters. On the network test page, click 'Show More Info' to see the upload speed.

First, we recommend that you purchase a dongle from Huawei or ZTE. Generally, these two brands' dongles can be used with YoloBox. You can refer to specific model recommendations:

• ZTE MF79U
• ZTE MF833v
• Huawei 3372h
• Huawei B535-933

If your USB dongle is not working, you can try the following methods:

1. Reset the USB dongle.
2. Factory reset YoloBox.
3. Adjust the network settings.

If none of these work, we suggest contacting contact@yololiv.com for assistance. It may be that this dongle is incompatible with YoloBox or due to other reasons.

Generally, when YoloDeck is not working, it manifests in the following two ways.

YoloDeck Suddenly Stops Responding: The YoloDeck was working fine, but suddenly it's unresponsive.

• Solution: A common cause of this issue is a loose or faulty USB connection. When the cable is in poor connection, the YoloDeck might not communicate properly with your YoloBox.
• What to do: Try replacing the USB cable with a new one. We recommend using a high-quality USB-A to USB-C or USB-C to USB-C cable. Usually, these tend to provide a more reliable connection. Check that the cable is fully functional at both ends to ensure a stable connection.

YoloDeck Stuck on the Logo Screen: The YoloDeck is stuck on the YoloBox logo screen and doesn't progress to the event interface.

• Solution: This issue often happens if you plug the YoloDeck after entering or starting the live events. The device may not initialize properly if you plug it in after the event has begun.
• What to do: To avoid this, always connect your YoloDeck before entering the event. Plugging in the YoloDeck before you begin streaming ensures that it syncs up correctly with the YoloBox.

First, please understand that the bitrate displayed in the upper left corner of YoloBox shows the real-time transmission bitrate. This bitrate represents real-time data. If the upload speed is not stable, you may experience data accumulation, followed by a rapid upload once the internet speed stabilizes.

This can cause the bitrate in the upper left corner to spike. However, if you check the video after your live stream, you'll find that it is actually the bitrate you set.

Some users may use other software to monitor the live bitrate.

There have been instances where zooming in or out with the camera caused rapid changes in the bitrate. This is normal because when using the zoom function to enlarge the image, the details in the picture become richer and more complex. Whether it's optical or digital zoom, the encoder needs more data to maintain image quality when processing these complex scenes, so it automatically increases the encoded bitrate.

YoloBox has a feature in the video source section called 'Livestream'. Using this feature, you can remotely access the live streams of other YoloBox devices as a video source.

However, there are some limitations to this feature:

1. You need multiple YoloBox devices, all logged into the same account.
2. All YoloBox devices must be using the multistreaming service.
3. The live stream must be 'on air'; simply creating a live event is not sufficient.

The issue isn't with your YoloBox or the video file itself — it's with the audio format.

For example, if your video is in MOV format, YoloBox Ultra can play it. However, if the audio within that MOV file is encoded in an unsupported format like PCM_S16BE, you'll run into problems.

To ensure your video files play correctly with audio on YoloBox, please use one of the following supported audio formats: AAC (Recommended), MP3, WAV, FLAC.

If you experience this issue, the easiest fix is to convert your video to MP4 with an AAC audio track. MP4 is the most widely supported format and works seamlessly with YoloBox.

How to Convert Your Video: Use a free tool like Cloudconvert or FFmpeg.

There are many possible reasons for this:

1. Device Limitations: The YoloBox Pro can only accept one 4K local video, so you may only be able to add one.
2. Video Format: Generally, local videos in MP4, MOV, and WAV formats can be used normally. However, note that YoloBox currently does not support local videos with an alpha channel.
3. Video Name: If your local video name contains special characters, such as *&¥?, it may not be readable. Once you modify the name, it should work normally.

It's because the YoloBox battery is fully depleted, and it doesn't have enough power to start the system. If you use a regular charger and cable, the device will keep trying to turn on as soon as it gets a little bit of power. But because that power isn't enough, it ends up stuck in a loop — flashing the logo, then powering off again.

How to Fix It:

1. Use the original 45W charger and the white USB-C to USB-C cable that came with your YoloBox. Plug this into the dedicated charging port (the other one is the data transfer USB-C port).
2. At the same time, use another USB-C charger and USB-C to USB-C cable (any decent quality one will do), and plug it into the data transfer USB-C port (Type-C).
3. Leave it like this for a while — usually 15 to 30 minutes. The dual power input helps provide just enough charge to stabilize the battery.
4. After some time, you'll notice the device is no longer stuck flashing the logo. It will eventually have enough battery to boot up normally.

This is likely because the Atomos HDMI in setting is set to 2.0. You need to change the HDMI in setting on Atomos to 1.4 for the Extreme HDMI output.

First, please confirm the format of the SD card/USB stick/SSD. If the SD card is in exFAT or NTFS format, there is no file size limit. However, if the SD card is FAT32, there is a 3.5 GB file size limit. Even if you choose continuous recording, the files will still be split.

Please note that for SD cards smaller than 64GB, only the FAT32 format can be used (according to the SD Association's documentation, Windows can format to exFAT, but this is not standard usage). Therefore, we recommend using an SD card with a capacity of 64GB or more, formatted as exFAT or NTFS, so that individual recording files can exceed 3.5 GB.

For YoloBox Ultra: You can purchase the 1080p touchscreen monitor. Use the USB cable to connect the two devices. The Ultra USB-C port → the monitor USB port.

For YoloBox Extreme: Please make sure you're buying the correct type of monitor. You'll need a monitor that meets both of these requirements:

• 2.5K resolution
• USB-C port for data transfer

The YoloBox Extreme needs two cables to fully connect to a touchscreen monitor:

1. HDMI Out from the Extreme → HDMI In on the monitor
2. USB-C (Data Port) from the Extreme → USB-C on the monitor

This situation is easy to handle. First, click to enter the 'on air' live event, then click 'Go Live' (don't worry, it won't actually go live again). After that, end the live again. When you exit the live event, you'll find that it has changed to 'Ended,' and you can delete it.

You can stream to both horizontal and vertical platforms at the same time — but it's important to understand that YoloBox cannot output both horizontal and vertical video orientations simultaneously. You'll need to pick one video orientation (horizontal or vertical), and then choose your streaming platforms accordingly.

Here's how it works:

Option 1: Choose Horizontal Mode

In this mode, your project is in 16:9 format — perfect for YouTube, Facebook, Twitch, and other traditional platforms. You can stream directly to these platforms using YoloBox's built-in integrations or via RTMP (e.g. for Vimeo, Kick, etc.).

If you also want to stream to vertical platforms like TikTok or Instagram while using horizontal mode: You'll need to use RTMP for these vertical platforms.

• Getting the Instagram RTMP key is easy: just switch your account to a Business Account. We have a blog that walks you through this process: How to stream to Instagram Live with YoloBox.
• TikTok is a bit more complex — you may need third-party tools or reach out to TikTok to gain RTMP access.

Option 2: Choose Vertical Mode

This sets your project in a 9:16 format, designed for TikTok, Instagram, and similar mobile-first platforms. YoloBox comes with pre-installed vertical apps like TikTok and Instagram. Just log in and stream. You can also install or update more apps (like Facebook, Shopee, etc.) via APKPure.

Want to stream to horizontal platforms from vertical mode? Use RTMP to send your 9:16 stream to YouTube, or any other RTMP-compatible destination.

Pro Tip: In vertical mode, you can use Two-App Streaming, which lets you go live to TikTok and Instagram simultaneously — and still stream to other platforms via RTMP.

There are two possible reasons why you haven't received the update yet:

The update is still in a gradual rollout (grayscale release). Updates are pushed in batches based on device activity — the more active your YoloBox has been recently, the sooner you'll receive it. If you'd like early access, feel free to reach out to Josh Gately on Facebook.

You are not logged into your YoloLiv account. Make sure you're signed in on your YoloBox. Updates are only delivered to devices with an active YoloLiv account.

You have two options for the repair:

1. Contact YoloLiv for repair.
2. Repair the battery yourself.

Here are the full steps:

1. Log in to YoloCast from your computer or phone using your YoloLiv account.
2. Find 'Destination' and click 'Add Platform'. Choose the 'RTMP' option.
3. Fill in the server URL and stream key.

Important note for streaming to Kick via RTMP: When setting up a stream to Kick using the RTMP method, be sure to modify the Stream URL provided by the platform. Specifically, you need to append /app at the end of the URL to ensure a successful connection.

Example:

• Original URL (from Kick): rtmp://fa723fc1b171.global-contribute.live-video.net
• Updated URL (what you should enter): rtmp://fa723fc1b171.global-contribute.live-video.net/app

The stream key remains unchanged. This simple adjustment is crucial for establishing a stable and functional stream connection with Kick.

If you notice your live stream appears flipped in apps like TikTok or Instagram:

1. Locate the "Video Adjustments" option in the right-side navigation menu.
2. Manually correct the orientation using Flip Horizontal/Vertical (mirror effect), Rotation (90° / 180° / 270° adjustments), and preview changes in real-time until properly aligned.

This is most likely related to your usage setup. First, check if you are using the USB-C port. If yes, please either avoid using it in this way or follow the correct connection method.

If you're connecting an external webcam (such as DJI Pocket 3): The Pocket 3 may treat the Ultra as a power bank, which can cause the Ultra to shut down automatically. In this case, we recommend using the USB-A port instead.

If you're connecting an external monitor: The monitor may also treat the Ultra as a power source. We recommend powering the monitor separately with a high-wattage charger to prevent this issue.

To set a static IP for your YoloBox Extreme:

1. First, connect your Ethernet cable to the device.
2. Go to Account Settings → Network.
3. Tap Ethernet to view your current network information.
4. You'll see an option to choose between Dynamic (DHCP) and Static IP.
5. Select Static IP, then enter your desired IP address, gateway, and DNS settings.

Once saved, your YoloBox Extreme will use the static IP each time it connects via Ethernet.

This usually happens because your Facebook account is not an admin of the Page you're trying to stream to. Only Page admins have permission to create live videos through YoloBox.

If you're unsure whether you are an admin, please watch the video below to learn how to check your Page role and update your permissions.

What if you are not listed as an Admin, but you are actually the creator of the Page?

Facebook sometimes changes Page roles or assigns the original creator as a "Task Access" owner instead of a true Admin. If this happens, here's the workaround:

1. Add someone you trust as an Admin of the Page.
2. Ask that person to add you back as an Admin.
3. After that, refresh your Facebook permissions on YoloBox and try again.

Currently, local video files with alpha channel are not supported. The only way to bring in alpha-channel graphics is through NDI.

Please follow the steps in the video below to set up NDI with alpha channel: How to Apply Alpha Channel on YoloBox Ultra.

Reload means reopening and reusing the same live event you used last time.

Duplicate creates a new live event by copying the previous one.

For more details, please check this tutorial video: Save Setting on YoloBox Extreme | Everything You Need to Know.

This is normal behavior and not a hardware issue. When the device is powered off but still charging, heat is generated. To protect the internal components, the cooling fan continues to run automatically. Once the device cools down or charging stops, the fan will turn off.
