Fuzzy generation result problem

Thank you for your outstanding contribution！ On the left is the original video frame, and on the right is the generated result. You can see that it has become much blurry. Is there any solution？

Same problem,the hair cannot be represented well.

I suspect the root cause is because the 3dmm landmark fit is slightly off. There appears to be some temporal smoothing (possibly caused by the euler/trans parameters being trained in batch) going on here, and the radnerf is trained on slightly erroneous alignments which may lead to poor convergence (seen this in previous nerf work).

The same problem reasoning results in a fuzzier result than the original video
