Stream pixelated when moving (For Twitch)

[Yennot]

Hello everyone, i saw that there is a lot of people who have this problem, and none of the fixs gave work for me.
I'm on streamlabs OBS, i use AMD encod and i fixed a bit rate at 6000, everything else i set to default
On the video part the canvas is 1080p and the output is the same, the downscale filter is Lanczos and common fps value at 59.94
I tried many many settings, the stream is always very smooth, but there is a high pixelisation.
I tried on record to put for exemple bit rate at 37k and like that i don't have pixels and it's perfect but twitch doesn't handle that much
On speed test i have a download of 900mb/s and an upload of 500mb/s
For the pc :
Processor : R5 3600
RAM : 16gb 3200mhz
GPU : Aorus Rx5700XT
Mb : Aorus b450 elite
HDD of 1TB and SSD of 1TB
Watercooling : MSI coreliquid 240R
Alim : Seasonic 620W
It's been a long time i'm trying to fix this problem and i can't find anything, so if you have a solution i'll take it !
Thanks for reading

You WILL have pixilation.

6000 will not give you pixelation free stream at 1080p/60 , there's just not enough bitrate to cover that resolution, especially in high movement games.

You need to downscale to either 1080p/30 or 720p60 (advised) if you want to reduce pixelation.

 

[Yennot]

Oh, alright, well i downscaled to 720/60, i do have less pixelisation, but i still have some :/

It's impossible to completely eliminate pixelation on streams

 

[MajorDrumKill]

Definitely best to output at 720p60 for streaming to Twitch. 6000 bitrate is just simply not enough to make anything look clean above that (MAYBE 1600x900, but even then, it's still noticeable). I also hear Bicubic filter is the best one to use as Lanczos is more for upscaling. I don't know how true that is, but worth a try.

 

[Yennot]

Oh alright, but so i'm not satisfied with how it looks, i mean on a phone you don't see anything, but if you go fullscreen with a computer, you'll clearly see them :/

 

[Yennot]

Yeah, i found Bicubic to be a bit better ^^

 

[Yennot]

But so well, I guess i'll have to wait that Twitch allows more than 6000 bitrate to do a clean stream :C

Yep... this is normal. You are fullscreening something less than your monitor's resolution so that will be expected. I too found myself obsessing over things like this, but really no one would be doing that on the regular. :)

 

[Yennot]

Alright, well i'll go with those setting then, and hope that viewers won't put my stream in fullscreen on their computer ^^
But thanks for all those answers guys, and have fun :D

In all honesty I think very few people watch Twitch in fullscreen.

I run my streams
Canvas: 2560x1440
Output: 1536x864
6000 bitrate

And they're pretty much spot on as you'd see on most Affiliated setups.
Though I switch to another profile (720p60) if streaming anything high paced.

Also ensure you're watching your stream back at Source rate
Settings > Quality > i.e 720p/60 (Source)

This will view the stream at the streamers pushed bitrate, rather than the lower suggested bitrate Twitch imposes for non affiliated streamers or above. Or auto-switches if end user watching has a slow connection etc.

hello The ZeTwitch program helped me download videos from Twitch

I really have this problem with my streams and it makes sense that downscaling the resolution is better because it’s less information to send however then how come whenever I look at other streamers and they are doing 1080p/60 how come I basically don’t notice any pixilation on their streams at all where as mine looks like absolute do do

Try adding a static border, post a link to a VOD with the issue and

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...
