Question / Help Stream looking pixelated

[Kohakz]

Hello,

Over the past few weeks I noticed that my stream looks quite pixelated, as how it would normally look when you have too little bandwith set for too high quality. In the first place I thought it's my CPU but after an upgrade to what now is an i7 4770k, I still have the same issues with presets on fast/er.

I used to stream at 1080p@30fps or 720p@60fps with a 2.750 bitrate (upload is 3.500) which looked perfectly fine. I now changed it to 720p@30fps where it still does the same.

What I already tried is:

• lowering quality
  setting x264encoding profile to "high"
  not using CFR
  streaming with VBR
  not streaming with CBR padding
  different Twitch servers and streaming sites (hitbox)
  lower and higher keyframe interval
  different resolution downscale filters

My PC-Specs are the following:

• CPU: i7 4770k
  GPU: GTX 780Ti
  RAM: 24GB 1600 MHz

Log file of a short test stream is in the attachments.

Thanks in advance
Kohakz

Do you have a link to a VOD or something? I mean those x264 presets won't overcome "low" bitrates that we have to use while streaming to kill all pixels. You can't expect a perfectly clean looking stream. It also depends on the source/game you are playing. The amount of pixelation will depend a lot on the motion as well. Those settings you have are perfectly fine in my opinion.

Here is a vod, connection dropped a little mid way: http://www.twitch.tv/kohakz/b/506371310

I know that my stream will by far not look perfect, but it used to look a lot better while eating less resources, which is what bothers me.

There are no videos o.o Well you really have to compare them side by side, anyways.

I have a picture of an old broadcast here at 720p@60fps

while this is one of how it currently is with 720@30 (please be aware that this is no motion on both pictures)

. It still looks okay, but as I said, not as good as it could and used to look.

It's impossible to say just based on screenshots. We'd have to see the log that created that recording, too.

It would be good to see a working VOD link, because at this point I think you might be expecting too much out of the quality you can get from streaming.

Sorry for the late reply.
I sadly don't have a VOD of an older stream anymore, only thing close to a VOD is this https://www.youtube.com/watch?v=MH5QGAv ... f_Q56STLzS , my VODs apparently don't get saved even though I have the feature turned on.
It's low motion and I put down the FPS but there're still pretty big pixel fields in the back. I know I expect a lot of how nice my stream should look, but it's really just due to the fact that it /used/ to look better.
