Stream pixelated when moving (For Twitch)

Stream pixelated when moving (For Twitch)

QUESTION:

"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"

ANSWER:

"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."
