Just started using obs. Lag is not really my issue. More so quality when viewing my stream in fullscreen..seems to be grainy with movement and stand still..
I am currently using a downscale from 1920x1080 to 1280x720 at 60fps with a 3000 bitrate/buffer. Quality is set at 10. And my cpuspeed is set at faster.

My download is 34 and upload is 6


Current specs on pc are: i5 3570k at 3.8ghz/16gb ram/1tb hdd/evga gtx 670ftw

Can someone help me maximize quality

Downscaling will always look "blurry" or "grainy" because of how the bilinear filter works.

Yeah, but don't do 60fps. Your system can likely handle it, but Flash player can't.

Honestly, what's wrong with the bit of blur? It's really not that bad.

yeah i was downing it to the 25fps and 30fps, it was beginning to look better but still grainy with the movement. im guessing being partnered with twitch would rid me of the uglyness grain correct? cause it looks great not fullscreened

The 60fps I think is more a CPU / processing limitation. It shouldn't use up much more bandwidth from what I see.

While streaming, are you seeing any dropped frames in the bottom right hand corner of OBS?

If you are trying to push quality 10 over 3000, you will likely be dropping frames left and right.

I'm usually running quality 8, 3500kbits and I get zero dropped frames. If I push that to quality 10, I start getting dropped frames as the quality forced dropped frames in action scenes.

If you are using VBR, you will get spikes using quality 10 where it can go much higher than the 3000 you have set.

Twitch actually recommends people use CBR in their support pages. I've just started testing this now, it is a good way to see if you will get any dropped frames.

So with quality 8, 720p, 60fps my connection can handle 3800 bit rate with only a handful dropped frames.

The other thing to check is which server you are streaming to. The global load balancer can be temperamental at times. It's best to find a server closest to you and pick that one manually. Then of course you get load - you might be able to stream fine in off peak but in peak hours start getting bandwidth issues on Twitches end.

So it's best to allow for some overhead. So to be rock solid, I for example would go for Quality 7, 3500, CBR. Nothing over the Internet is easy lol.

just tried the CBR, worked great. i am using 3700 bit rate/buffer and quality 10 and 720p with 60fps.

looks hella better then before. if anyone has any further suggestions please let me know. always wanting to improve on the stream. thanks a bunch Bthomson. I been messing with this all day ha

now also my other question is. with the high bitrate. are people going to be able to watch my stream? or should i lower it to the normal 2800 for everyone to be able to view?

I just don't understand how lower bitrate people at 2800 or even 2500 have smoother streams and less or same pc performance/download upload. Maybe more suggestions?

Well I think you'll find they drop the quality to compensate.

Quality of 5 or 6 will still look "Decent" yet is miles smoother as there is more overhead for action. It can still look as good as a quality 10 (of the same bit rate) when nothing is happening, it just allows for the minimum quality to drop when required. In fast action scenes, the quality will be allowed to drop down in preference of smooth display.

However, the average quality will drop. Seeing as it happens during fast motion though, sometimes it doesn't matter that the quality briefly drops as most people prefer a smooth experience over a quality experience.

By setting Quality 10, you are saying you don't care if it has to drop frames, as long as all the frames sent are high quality. By setting quality 6 you are saying "Send high quality when you can, but if it has to choose between quality and dropped frames, send the frame at lower quality".

I'm pretty sure that's how it works, someone please correct me if I'm wrong though.

i did notice that, and 6-7 with 2800 or even 2500 give me a smoother stream. but still a lil fuzzy. i know im capable of running at 1080, but 1080 looks horrible

Here's an example of my stream quality: http://www.twitch.tv/tag_simplyfresh/b/379918005

It doesn't look blurry or grainy, at least not to me or people that have watched my stream.

Quality: 6
Bitrate / Buffer: 3000
Audio: AAC / 96

Base Resolution: 1920 x 1080
Resolution Downscale: 1280 x 720
Frames-per-second: 60
Disable Aero on start-up: Check

Process Priority Class: High
x264 CPU Preset: Medium
Bind to Interface: *your ip address*

You can also see some video's I have streaming 1080p @ 30fps. It looks amazing!
