Hey i have recently got into streaming but have been having problems fine tuning my obs settings, as seen in this vod whenever i move the screen becomes pixelated, i was wondering if maybe there is anything i can fine tune to prevent this maybe?

Pc build
CPU - Intel Core i7 5820K @ 3.30GHz
CPU Cooler - Corsair Hydro H110i GT
RAM - 16 GB DDR4 2133Mhz
GPU - GeForce GTX 980 ACX 2.0
Mobo - MSI X99A SLI PLUS
Webcam - Logitech C920 HD

Obs settings
Bitrate- 2800 buffer- 2800

Res - 1920x1080 downscaled to 1.25 (1536x864)
Filter - Lanczos
Fps - 50

Process priority class- Normal
Buffering time - 700
CPU preset- very fast
Encoding profile- main
Keyframe interval - 2

Thankyou, just ask for any more information if required!
 
try "faster" preset and if that not help lower your scale to 720p.

btw, that quality is good with that bitrate.

i dont think its the bitrate, as i could stream woth 3000 bitrate since most people wont be able to watch it :< and i have already tried downscaling to 720 it didnt really help :/
 
Try 1280x720 at 30fps instead.

50 and 48fps are really odd values and may be introducing some of the picture distortion.
 
yes it is the bitrate, aytually it is the combination of bitrate/resolution/fps.

lol doesnt have that much movement on screen with colour changes and so on.

csgo has tons of colour changes and a whole screen movement when ever you move ingame or your field of view just a bit.

i know you are streaming 1080p50 but i will go with the "1080p60" (doesnt matter at this point)


streaming 1080p60 is more than double of pixels you would have with 720p60 which logically needs a higher bitrate to achieve the same picture quality. also your viewers have to decode 1080p60 through the flash player and flash ist just extremly inefficient and takes way too much resources which causes older dual cores to litereally max out the cpu by just watching a stream. (720p60 is also quite taxing but way more efficient on flash)

what do you pay for using 720p60 - well usually you have some sort of distortion/blurriness on sharp lines e.g. fonts. this is actually not as bad as it sounds but its noticeable, does your viewer care about it? no absolutely not, thats not the point why they are watching you.


so to get to the important point.

if you want 1080p stream 1080p30 if you want 60 fps stream 720p60

as borderline rules for unpartnered streamers its actually recommended using 720p30 with 2000-2500 bitrate due to buffering issues, even at ~2k bitrate it is literally cancer for some none-partners, but as a keynote as long as you dont go over 3500 bitrate twitch wont be mad at you and if your viewer can watch it without compaining then go with it.


with a 5820k you should be able to do 720p60 on medium preset and 2500bitrate (presets dont do miracles but they help you if you got that kind of cpu, but it can always cause performance decrease, thats why streaming is about testing what works best for you)

Click to expand...
Trust me , if you scale to 1280, use 3,000 bitrate, and stream at 60 or 48 fps then it'll be alot less pixelated if your pc/internet can handle it.
