Question / Help My stream's quality suck ballz :o Help ?

Rough · Jul 2, 2013

I dont get it,it should be 720p...But it looks like 480p or something...
At first,I thought it was because of the opencl=true...
So,first VOD with opencl=true.

Then,I disabled opencl by unticking the "custom x264 encoder settings",but quality stayed the same,I guess..

Heeeeeeeeeeelp ?

bitkid · Jul 3, 2013

Try CBR (constant bit rate) and try bumping the buffer size up a bit.

Krazy · Jul 3, 2013

There is literally nothing wrong with your VOD. That is about the quality you should expect with 2500 bitrate on faster preset for your chosen resolution/fps

FerretBomb · Jul 3, 2013

Looks fine. Try setting your downscale to deliver 480p, you'll see the actual difference at that point.
I'd also recommend NOT running a buffer smaller than your bitrate; it can lead to chop, stutter and other issues.

Rough · Jul 3, 2013

http://www.twitch.tv/irs0osooom/b/425147676
downscale 2.00 to 960/540.
quality here is more blurry than before,Im trying to achieve the opposite..
And this one is on native resolution without downscaling
http://www.twitch.tv/irs0osooom/b/425150082
But it seems that my internet struggles without downscale..

ThoNohT · Jul 3, 2013

Is 60 fps absolutely necessary for Diablo III? Setting that to 30 would give you some more available bitrate for quality. The stream looks good though from the quick glance I took at it, no time to look in detail now.
Enabling CBR might actually have an effect, your first two vods are without CBR and a quality balance of 10. This will provide good quality when nothing happens, but it will suffer once the scene becomes more dynamic. I would suggest a quality balance of 8 in stead.

Rough · Jul 6, 2013

So about opencl? Should I use it or not ?..

Krazy · Jul 6, 2013

I wouldn't recommend it. It's very buggy right now, and it's really only a performance feature, not a quality feature.

Rough · Jul 7, 2013

Is there any quality feature that I can use?

Xianahru · Jul 7, 2013

There is no 'quality feature'. You need to throw more bitrate at it and may get away with a lower preset to increase compression and quality. But that costs a lot of CPUpower.

vaesauce · Jul 7, 2013

If you know any of the custom settings commands you could probably get away with some Extra quality and faster encoding. Other than that, it doesn't really look that bad.

Kharay · Jul 7, 2013

Krazy said:

Very buggy... on specific sets of hardware. However, I would not readily recommend against using it just for that reason alone. There are numerous sets of hardware on which OBS with OpenCL runs just fine. And the fact it is a performance feature is actually quite useful for quality as well. If you can offload some of the encoding to the GPU you may end up freeing up enough CPU cycles to go with a different CPU preset and increase quality that way.

It's worth a try and besides, the more feedback we have on what hardware it does work on and what hardware it does not work on, the more we can arrive at possible workarounds, possible fixes or just possible bugreports to send to the x264 crew.

Rough · Jul 7, 2013

Well,I have quite a fine rig imo..
3770k @ 4.5ghz,gtx titan,16 gigs 2400mhz ram..
I can post some logs for inspection if you'd like.

Question / Help My stream's quality suck ballz :o Help ?
