Camera name

Change the NDI camera name (this is the name that will be used to identify the camera in the NDI environment).

Video encoding

Select from Full NDI, HX2 HEVC, or HX2 H.264.

Note: NX2 is about 1/10 the size of Full NDI but at roughly the same quality.

- HX2 (HEVC and H.264) is only available with a subscription.

- If you are having trouble viewing HEVC video with Windows broadcast software, you can install "HEVC Video Extensions".

NDI is a video over IP protocol developed by NewTek that delivers high-quality and low-latency video. NDI HX is the latest high efficiency version of NDI that is capable of delivering high-quality video in a smaller package than Full NDI.

- When using broadcast software on Mac OS: Set Low Latency to "OFF" when using H.264, but HEVC can be used as is.

[SRT (HEVC and H.264) ]

SRT will usually have about 2-3 seconds of latency, however, it is possible to send high quality streams from outside the studio, even when using cellular data transfer options, like docomo, au, Softbank, or Rakuten.


By entering the URL and stream key, the image can be directly streamed during live broadcasts on Youtube, etc. Bitrate can be set from 1 to 20 MB.


Select a resolution.

- If you are using 4K, we recommend using HEVC.

SRT TalkBack

The function can be enabled by turning on Use Talkback via SRT.

When using TalkBack, we recommend using "Wired earphones" or "Bluetooth earphones".

Some earphones will use the Bluetooth microphone, so please select the video microphone from "Built in Microphone" or "Bluetooth Microphone" in the "Video" settings.

If TalkBack is connected normally, the message "SRT-TalkBack ONLINE" will be displayed.

Freme rate

Select a frame rate.


Select a bit rate. A higher bit rate will generally lead to a better stream quality.

Recommended bit rate for HEVC

  • 4K: around 15M

  • 1920×1080: around 9M

  • 1280×720: around 6M

  • 640×480: around 3M

It will also be possible to adjust "Video Bitrate (2 to 20 MB)" according to the application.
