OBS Changes - Keyframe Interval

ThePurv

Twitch is currently issuing a warning in preparation for their switch to HLS if you don't have a keyframe interval set. By default, OBS relies on the x264 auto keyframe interval, which puts keyframes at scenecuts for the best quality. Unfortunately this is incompatible with HLS which needs fixed size GOPs, for which Twitch wants a 2 second keyframe interval.

v0.55b or higher:
To change your keyframe interval, goto Settings, Advanced, and enter 2 seconds into the keyframe interval box

I just changed my settings this morning and it seems to be doing better.
