Hello, as the title says I have a question about Twitch quality options.

Does anyone know what encoder settings is Twitch using for their 160, 360, 480, 720, 720p60 quality options?

The 720p60fps quality option is going out at 3000 bitrate and it looks way better then it should for 3000 bitrate only. If I was about to use only 3000 bitrate for a 720p 60 fps stream, I would never achieve such a nice quality. Feels as if I can translate it to OBS... that Twtich might use a better x264 preset (default is Very fast) and they use maybe Slow or so?

Example:

Live at 1080p60 8000 bitrate Source, is Raw from the streamer. Everything under it is encoded again by Twitch.
720p60 is at 3000 bitrate,
720p is at 2000 bitrate, etc.

My point is, even if you live stream yourself at 720p60 at 3000 bitrate, it does not look as good as twitch re-encodes to that.
There is maybe a way to achieve that quality at lower bitrates (as twitch does) with Obs settings, which settings would those be is what I am asking if someone knows.

Twitch cannot improve the quality over what it is given. A streamer who is uploading 1080p60 is being transcoded to 720p60, that looks better than your native 720p60 because Twitch is starting with higher quality and downsampling, and because they are probably dedicating more CPU to that task than you can.

If you want to improve the quality of your 720p60 stream while keeping the resolution, framerate, and bitrate the same, there is one answer: slower CPU preset.
