Question / Help Streaming with low bandwith: quality issues

[Servant Archer]

My system: i7-3930K @ 3,20Ghz, 16BG RAM @ 1066, NVIDIA GeForce GTX 670. It can handle a video process at maximum quality without problems.

The real problem is the upload bandwith: http://www.speedtest.net/result/2804604121.png. Here, in Italy, providers won't allow you to have bandwith to avoid you doing something by your own (like setting up a personal server). And for that 0.80mb/s of upload I pay extra fees to my provider, too.

Wanted to stream League of Legends: at around 500kb/sec of Max Bitrate is fine, I don't lag too much in game and the stream is fluid. Going further is not advised. But the video quality is really poor and I really don't know why. I can set up OBS to elaborate the video at MAXIMUM settings, like SLOW CPU preset, multithread optimization (6 cores + 6 virtual cores), 1:1 resolution, etc. but if in game I stay STILL the quality is somewhat good, men I move my character all goes terribly BLUR, pixelled.

I bet you, I tried to change THOUSAND of settings, tried to work on buffers, audio buffers, resolution downscale, FPS, quality balance, I literally spent like one entire day but no success. And I mean: I can't find any options that seems to improve the quality. Also, I don't know what some options mean (like Scene Buffering Time, Filter (under the Resolution Downscale option), etc.), so most of the time I change settings hoping "something" will happen.

I don't want to stream at 1080p with 500kb/s of upload, I'm not a fool. But at least I want to get a clear, non-blurred, video. Any suggestions?

Go to http://testmy.net/upload and select NL server and test 6MB upload test. Tried to play with settings at 500kbps and had no luck with quality. You should really need atleast 1mbps to get decent quality and resolution.

EDIT: Have you tried turning on "minimize network impact" on broadcast settings?

724 Kbps (91 kB/s).

I find really strange that I get this "motion blur" in my videos. I mean, it's seems more than a quality/system/video compression issue than a bandwith one.

EDIT: Have you tried turning on "minimize network impact" on broadcast settings?

Yes, seems to not have effects on quality.

It really is simply a matter of having enough upload. Cranking up the quality of your compression on your computer will only go so far. The fact of the matter is that movement takes a lot more bandwidth to transmit, and with that bit rate, it will always be blurry in some way. The best thing you can do is to lower your OBS resolution to 480p or maybe a bit lower, so that the difference between movement and standing still isn't so stark. (i.e. standing still won't look as good, but movement won't look as bad.)

My native resolution is 1920x1080, I downscale it to 1.5. Should I go 2.0 or even more? Filters, CBR, Buffer Size and Scene Buffering Time have some impact?

Downscale it with the Lanczos filter by 2.25, which should give you 480p. Keep CBR enabled, and keep your bit rate and buffer both at 500. Leave Scene buffering time at the default.
