Hello,

So twitch just updated their reccomended settings for streaming.
I noticed on the lowbitrate streams, they added suggested keyframe interval of 6-10 seconds.
What does this actually do, and why does only lowbitrate streams benefit from this.

I'm currently running a 1k bitrate stream at 480p 30fps on slower or veryslow preset.
Sometimes i change to 540p or 720p depending on the game, always with slower or veryslow preset.
Sometimes I'm still getting pixelation on grass and small text, will this keyframe interval help with that at all?

Thanks

A keyframe contains all the information, while the other frames just tell what's changed since the last keyframe. Go ahead and try, maybe it'll help; It would make sense.

Everything else equal, a longer keyframe interval will encode more efficiently in terms of quality per bitrate than a shorter keyframe interval. So go ahead and try it at 10 seconds. The downside is that its harder on the downloading bit. But a 1k bitrate stream is pretty easy to download so I guess Twitch figures its no big deal.
