What exactly is the problem? The blurriness when panning the camera? If so, try turning on "Ignore streaming service setting recommendations" in OBS Settings (Settings > Stream > Advanced Options)

Please follow this guide, and post a log file.

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...

It just seems to me like the YouTube one is encoded in AV1, which performs really well in motion with picture quality. H.264 is bad in motion particularly with AMD GPUs.

In Twitch, make sure to follow the limits of 8k Bitrate, 1080p Video Output Resolution. I think Twitch still downgrades your stream if you go over those settings.

Are you using H.264 Encoder on both live streaming platforms? What bitrate and encoder settings do you use on Twitch and YouTube?

25k and 8k bitrates have a significant difference in terms of motion picture quality.

If you're willing to sacrifice some performance when streaming on Twitch, you can try to let your CPU handle the encoding by using x264 encoder. It's just a shame that AMD's implementation of H.264 is not good on low bitrates unfortunately.

If only Twitch already supports HEVC(H.265) or AV1 encoding, or as much bitrate that YouTube allows, this wouldn't really be much of a problem for AMD GPUs.

so if it was the encoder tell me why does the 4k 30fps thats bare minimum bit rate look clear and the 1080p Requires at lest 10k to get no Blurry issue on av1 and H.264 and H.265 its not the encoder thats the issue its somthing in the software with obs or twitch cause my gpu barely works when encoding it only stresses at 4k 1080p encoding 20% 1440p 65 to 70% and 4k maxs out. i lose 4 FPS in 4k?

Different Encoders have different capabilities in Video Quality, AV1 is currently the best at low bitrates.

You can check the low bitrate comparisons of different encoders on this video at the 1:50 mark

Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube.

But do know, the GPU tested in the video is an NVIDIA GPU. Again, H.264 on an AMD GPU is noticeably worse.

Video Encode usage doesn't necessarily completely define how good the Picture Quality will be, the resolution helps of course. We're talking about Video Encoders/Codecs (x264, H.264, HEVC/H.265, AV1), each Video Encoder/Codec produce different results for the Picture Quality.

so the only reason why im saying it not the encoder its software is cause im using an amd cpu THE SAME ENCODER STUFF IS IN THE 7900XT SOOOOOOO if the 264. is a good (software) to use then the gpu (software) IS THE ISSUE
