Bug Report Blur on stream [settings issue]

If I stream from any version after 0.571b I get this strange blur on my stream, but not in the local preview.
http://www.twitch.tv/toxijuice/b/488756649

I can close OBS, reopen it, and start streaming over and over until it works, it seems completely random.
I have also tried different things like starting from a blank scene, starting the stream, and then adding things to it without any luck.

I believe the last version that works for me is 0.571b, but I could be wrong. I could test versions one by one until I get the issue, but the issue is inconsistent and would require much testing on each version, even if it seemed to work.

Re: Blur on stream only in newer versions of OBS

Preview does not show encoding quality, it shows the base capture image, which is unmodified by anything.

Your settings are what is the trouble here, not OBS or the version of OBS. Encoding isn't done in any of OBS' code, encoding is done by the best AVC encoder library currently available: x264.

The problem with your settings are the following:

1.) You have insufficient bitrate to support 1080p 60fps, 1080p 60fps requires at least 4000 (and only just barely the minimum for 1080p 60fps). I would recommend turning down the resolution and/or FPS to accommodate twitch's lower bitrate requirements. If you have 3000 bitrate available, I would recommend just using 1.5 downscale so you stream at 720p 60fps, which is more fitting for 3000 bitrate.

2.) You manually set your keyframe interval to 60 while having 60 FPS, which means that your keyframe interval is exactly one second. Lower keyframe intervals than the recommended interval will reduce quality. You should remove the text from custom x264 settings and use the "Keyframe Interval (seconds)" option instead to set your keyframe interval to 2 seconds.

Hm. That's very interesting. I have a profile that I tried using a while back that has very similar settings, but I was using a different profile when this log was created. Could OBS, theoretically, be using the wrong profile? I don't see how it could, but yeah.
