When a streamer is live, they're providing their audio/video content at a certain quality level: for example, 720p or 1080p. The higher the quality, the more data they need to send and the better the internet upload rate they need.
Similarly - to watch that stream - a viewer must have fast enough internet and download rate to continuously receive that video content! If the viewer's download rate is slower than required, the stream will constantly buffer!
Transcoding is the conversion of one format to another; in Mixer's case, the conversion of a larger, higher quality rate to a smaller, lower quality one.
- For example: from a 1080p source down to 480p
It can help to prevent buffering when a viewer has slower internet or simply allow a viewer to lessen how much bandwidth they're using, if they don't mind the lower quality video.
How to enable transcodes:
- Partner streamers can transcode to 720p, 480p, and 240p.
- Stream source must be 1080p or lower to receive transcodes. If the source is higher than 1080p transcodes will not be generated.
