I play League and it seems that my stream quality is bad. Any help would be appreciated. I'm sure it has something to do with my settings. I would like to play and be able to have the stream at least watchable.

From the log, it appears that OBS isn't the issue.
What is the problem, exactly? Why is it 'unwatchable'? Do you have a VOD link demonstrating the issue (you may have to turn on 'record broadcasts' on Twitch to have these available)?

My assumption would be that your viewers are getting a LOT of stutter. This is because you're casting at 3500kbps, which is WAY higher than most viewers' connections can deal with. The recommended limit for a non-partnered streamer is 2000kbps, which is enough for a decent-quality 720p@45fps stream, or a good-quality 720p@30fps stream. If people are still getting stutter, 1500kbps is enough for a decent-quality 720@30 stream.

Also, you'll probably want to run a 6MB test at http://testmy.net/upload to get an accurate view of your constant upstream throughput... speedtest is worthless for livestreamers. That said, it doesn't look like you're dropping frames, so you're probably fine on that. More mentioned as a by-the-way than something that would help.

It appears that you didn't actually go in-game on that log; for League, you want to use a Window Capture for the out-of-game client (champ picking, queueing, etc) and a Game Capture source for the in-game executable.
I'd also recommend dropping to 96kbps AAC audio, or 128kbps at most. Anything more is pretty much just a waste of bandwidth. (MP3 needs higher bitrates to sound good, AAC doesn't. You should be using AAC if possible. MP3 is only really there for older systems that can't use AAC.)

Click to expand...

So what you're telling me is 3500 is to high of a bit rate to stream at for non-partnered streamers. Ok I'll change that.

I must have posted the wrong log, I'll fix that tonight. A and I'll also get a vod to post. Thanks for the response!

I told twitch to save the broadcast but it doesn't show up?

The ultrafast preset is reserved for the lowliest of CPUs. Since you have a 2600K you should at least put that back to the OBS default of veryfast, and for a game like League you can probably bump it to faster or fast. These presets compress the video more, which in turn means better quality at the cost of more work for your CPU, but since you have a good CPU and are playing a fairly undemanding game it shouldn't be an issue.

Stop using monitor capture. Use game capture or window capture instead. Monitor capture in Windows 7 is the least efficient capture method and is why you're seeing so many late/lagged/duplicate frames.

Since you're streaming to Twitch you'll probably want to comply with their other broadcast "requirements" (encouraged but not enforced) - enable CBR under Settings > Encoding, and set your keyframe interval to 2 seconds under Settings > Advanced.

I only monitor capture out of game.

Thanks for the info, I'll update you here soon.

Here's a link to my stream if you have a few minutes to watch and see http://www.twitch.tv/joshynr

Also, does setting an affinity for OBS help at all?

The quality looks good to me.

Generally no, manually setting core affinities won't help and in many cases hurts performance.
