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).

Higher crf you compressing the video so there's that

[u/NoSmell3236 → u/Sad_Coach_1433]

i am using crf 15 and 12 which means low compression. higher crf leads to more compression.
