About Bitrate

You can manually select the bitrate from 1Mbps, 6Mbps, and 60Mbps. Please make sure that the total bitrate of video and audio is less than or equal to the selected bitrate.

For 1Mbps, the video will be streamed with quality on smartphones by default. Please use it for streaming up to 720p.

For 6Mbps, video streams in original quality on a PC. On the TwitCasting app, change the quality to "Source Quality(HQ). "

The 60Mbps is capable of streaming up to 4K, but the video will be re-encoded and the video quality will be optimized for all devices. Use the bitrate that best suits your network environment.

If the bitrate cannot be determined correctly with auto detect mode, such as when streaming x264, please use the manual setting.

For audio, encode in aac and set a bitrate of 128 kbps to 256 kbps. Set the sample rate to either 48 kHz or 44.1 kHz.

What is NVENC?

NVENC is an encoder that can be used with supported Nvidia graphics cards, allowing you to play games with a lower load than x264. Encoders for graphics cards other than Nvidia are also available. For example, if you are using an AMD graphics card, it may be displayed as "AMD HW H.264" or similar.
If you do not have a compatible graphics card or are unsure, please use x264.
* Note: In addition to NVENC H.264, NVENC HEVC is also supported (H.264 is recommended).

What should I do if the streaming video is choppy?

If your PC's processing speed is not fast enough to handle the streaming, please lower the output resolution or frame rate. Even if the processing speed of your PC is fast enough, the bandwidth of the Internet connection may not be enough, and the video may be choppy. In this case, try lowering the bitrate settings. If the video is choppy only for a specific game, you may be able to improve it by running the streaming software (such as OBS Studio) with administrator privileges.

How can I reduce latency?(For using link features)

To reduce latency, configure your streaming software to avoid outputting B-frames.

For OBS Studio:

Go to Settings > Output, then set Output Mode at the top to Advanced.
Depending on your streaming setup, apply one of the following settings:

• If your encoder settings have an "x264 Options" field, enter tune=zerolatency.
• If your encoder settings include a "Max B-frames" option, set it to 0.
• If there is an option labeled "Use B-frames", make sure to uncheck it.
• If your encoder settings include a "Profile" option and baseline is selectable, choose baseline.
