I'm quite new to OBS so I would like some help with this stream quality problem that I am having.


Basically, when I stream through OBS in World of Warcraft (only game i've tried so far) - when I stand still the stream quality is high... however, when I start moving the quality goes 8bit.

This only appears on the content that's broadcasted on twitch, when I view the content through (on the client), it's very clear.


Here's an example of one of my past broadcasts :
http://www.twitch.tv/mad_emo/b/539889196


Notice how I stand still it's high quality? But when I move it becomes 8bit?



I'm thinking it's a videocard issue maybe? somehow? Even though it's clear through OBS? My upload rate is 5mb up and i'm always at low low low MS when streaming... so im not sure.

I have a GTX 560ti ... it's old but definately good sufficient.

Maybe it's an upload rate issue? Maybe an option under twitch to upload high quality? im not sure.. HELP!

That's just how video codecs work. The only thing you can do about it is increasing your bitrate or lowering your resolution.

okay I increased my bit rate... and it fixed the glitchy view problem ... i left it at 128 and changed max bitrate to 5000. ... however, now, my stream freezes occasionally.

Anyone know the optimal settings based on my log?
