So think if you're during a cutscene and your viewers with a 10mbps internet connection buffer around 5-10 seconds of your stream encoded at 2mbps, and then you're suddenly sending them 30-40 mbps for around 5 seconds. So twitch takes you video and delays it by a few seconds and then sends different formats to your viewers, which also buffer (keep in memory a few seconds of video) so that if their internet connection speed fluctuates, they have a reserve of a few seconds to recover before the video stutters or pauses.

#Obs studio recording affecting encoding 720p

Twitch has to receive your stream and re-compresses it in real time in different resolutions like 720p or 360p, not all your viewers view your source stream. but think what happens on your viewers' side. However, when that explosion happens or when you get out of options menu, suddenly there's lots of motion and things happening, so codec says hey, i saved so many bits in the previous seconds so let's use 20-30 mbps for a few seconds to preserve as much quality as possible. or even better, you pause the game to go in the options menu to change some settings and then you get out and move again in the game.ĭuring that cutscene when there's just two people talking and everything else around doesn't change, or when your game is paused and only some options change on screen, the compressor will detect there's little motion, so instead of using 10 mbps to compress the image, it may use only 2-3 mbps because that's enough. So for example, imagine that your encoding settings are 10 mbps VBR, and you're in a cutscene where two people are talking and at the end there's an explosion or something. If there's little motion on the screen, it will use less bytes to encode the image, if it's a lot of motion, it will use more. With VBR, the compressor will use different amounts of data depending on the scene. VBR is better for quality, but CBR is preferred by the streaming service and has other benefits for viewers.
