1. Can I stream to horizontal and vertical platforms at the same time?

No, YoloBox Ultra offers three modes: Streaming Mode, Vertical Mode, and Monitor Mode. In Streaming Mode, you can stream to horizontal platforms such as Facebook, YouTube, Twitch, or any other RTMP/SRT destinations. In Vertical Mode, you can stream to vertical platforms like Instagram and TikTok. However, simultaneous streaming to horizontal and vertical platforms is not supported.

2. How to Use ISO Recording?

Navigate to the Recording tab on Ultra, and choose the desired resolution and frame rate combinations for ISO recording:

  • 1080p30: 4*HDMI Input + 1*Program (Up to 5) 
  • 1080p60: 3*HDMI Input + 0*Program (Up to 3)
  • 1080p60: 2*HDMI Input + 1*Program (Up to 3)
  • 4K30*1 input + 1080p30* 3 inputs (Up to 4)
  • 4K30*1 input + 1080p60* 1 input (Up to 2)

ISO recording is limited to HDMI sources, which means, other video sources are not supported for ISO Recording. You can record 5 video sources, including 1 Program video and 4 HDMI sources. Please note that the ISO recordings won’t include any text or image overlays added on YoloBox Ultra. For a step-by-step guide, please visit:

3. What does H.265 support?

H.265 supports RTMP streaming (YouTube has been tested and is working, but Facebook and Twitch are not supported due to platform limitations), SRT streaming, and recording. Currently, NDI is not supported for H.265.

4. Does YoloBox Ultra support 4K streaming and recording?

Yes, YoloBox Ultra supports up to 4K streaming and recording with “Single-Platform Streaming” mode. If using “YoloLiv’s Multi-streaming Service”, the maximum resolution supported will be 1080P. And HDMI OUT doesn’t support 4K, instead 1080P60fps.

5. How many sources can I add to YoloBox Ultra?

You can now add 7 physical inputs including 4 HDMI, 2 USB-A, and 1 USB-C port. In addition to these inputs, you can incorporate 2 local videos, 1 image source (maximum 10 images), 1 PDF, and 3 IP sources including 1 NDI, 1 SRT, and 1 RTMP source. This allows for a total of 14 video sources to be utilized. Furthermore, YoloBox Ultra provides the flexibility to customize your display with various multiview options, such as PIP (Picture-in-Picture), Side-by-side, Split View, News Layout, 2 Views, and 3 Views.

While there are no strict upper limits on the number of sources you can add, we recommend keeping the total below 10 to avoid excessive CPU load. This ensures optimal performance and smooth operation of the YoloBox Ultra.
