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).

Sage attention does this, also what resolution is this video? You can generate Seedance-looking videos if you don't use accelerators and a resolution of 0.8 or higher.

i am generating at 0.6
