Question / Help Blurred stream when moving

[seuk]

I cant seem to get my stream to stop being blurry when moving while I am playing. Audio works fantastic, video when still or slightly moving is fantastic, just when I move faster it blurs.

Example of stream:

No nearly enough bitrate for your chosen resolution/FPS. 3000 bitrate minimum for decently quality 1080p, and that's at 30fps. Use CBR for more consistent network load. I don't recommend higher than 30fps for 1080p at all, the bandwith requirements are too much, the decoding requirements can get pretty absurd, and Flash generally does not handle high framerate, high resolution video very well at all.

For future reference, you should always post your entire log, don't truncate anything.

Seconded. Trying to run 1080 at anything higher than 30 will run into countless problems, not the least of which being that the Flash player itself won't be able to cope with that much data and will turn into a stutter-fest, even under the best circumstances. I'd even say that 3000kbps is where 1080@30 starts, and 3500 is recommended for decent quality.

1600 isn't even close. Time to temper some of those aspirations.
At 1600, you sould be able to run a decent-quality 720p@30fps stream. For 720@60, you're looking at starting around 2500kbps for something that doesn't look like crap.

Also note that audio bitrate isn't 'free'; it isn't counted toward the video bitrate you've set. 192-AAC is ridiculously wasteful; drop that to 96, or 128 at most.

Also, turn ON CBR, and set your keyframe interval to 2 if you're streaming to Twitch; it's required for their new standardization initiative, and missing too many of the requirements will result in the ingests deeming your feed 'incompatible', and to reject it completely.
