Many options like +J and +TH randomly create noise to improve the visual
appearance. Although they perfectly work on a single image, I think they create
visible noises in animation when the background of frames should be identical
for a smooth transition.

Do you have any advice for adjusting the command parameters to eliminate noises
as a result of the difference between frame pixels?

Or generally, any trick for FFmpeg video generation of POV-RAY images?

Correct - all images should be generated in a reproducible way - no crand or any
of the other jitter-type effects.

I myself have only ever used pretty simple settings.   height, width, and
antialiasing.

I haven't done one in a while, but I posted my command line options here:
