Question / Help Pixelation problems in OBS

Hi everyone, I've been playing a fast movement-heavy game lately and I've been noticing that my footage looks like crap with my current encoding setup...I thought it was good but I usually play other way less fast stuff so I probably just didn't notice... I should mention that, for this game, I'm using an Elgato HD60 S connected to my PS4.

This is a video where I can show you the problem in question: https://www.twitch.tv/videos/579789049 (around the 00:35 minute mark you can clearly see pixelation as I walk around)

This is the last LOG file from OBS: https://obsproject.com/logs/xSzQUu_71F5GHfKS

These are screenshots of my actual Output and Video Settings in OBS: https://imgur.com/a/zfiuXDt

Thanks!
 
That's the expected quality for your settings. You're encoding using Nvenc on a 900-series card, so it's a bit behind in the quality that's possible nowadays for hardware encoding. Plus, you're only feeding it 4000kbps -- for fast action, even for a 720p60 stream, this is a bit on the low end.

Plus, the specific part you bring up in your stream has a lot of grass. Grass does not compress well, and will almost always result in macroblocking.

The only real way to improve the quality is the main things:
- increase bitrate
- use a better quality encoder (if you can, use x264 veryfast or faster... your i5 may be able to handle it)
- lower resolution/framerate (which honestly is already done here -- I wouldn't suggest going below 720p60 if you've got 4000kbps to throw at it)
 
Eh, the 900-series NVENC is right around x264 Veryfast to Superfast. Swapping to software encoding isn't going to make much of a difference.

With that amount of detail, I'd try dropping to 720p30; 60fps is a luxury in almost all situations, outside of retrogames where it can be a requirement to show blitting transparency properly. With that amount of detail and foliage, 4000kbps could be enough to look decent on 720p30.
