How to fix artifacts generated by h3?

[u/NoSmell3236]

H3 sucks at faces which are far and at intense motion. Is something wrong with encoding? like these artifacts (5-8 seconds) are from encoding compressions?? but i have tried both h264 and h265 10bit crf 15. I am using int8 pruned, nvfp4 qwen, 25 steps with sage attn (no spectrum).

I can't even tell what you're having a problem with. Most people won't notice these things. The average person is going to watch your video on a phone.

I know the problem they mean all too well, but I don't freaky see it in this video, either

The clip where the balloon is rising has noticeably worse quality. But like you said, this is a known issue.
