Why is there a lot of noise？ #150

Closed wuyue0509 closed 1 year ago

wuyue0509 commented 1 year ago

image image image image image image image I just adjusted the parameters normally as before, but now except for the first frame of the picture, other frames start to appear noise. Is there a step I made a mistake?

Do you mean you have a prior video in which you did not have the noise problem? If so could you attach the deforum output settings.txt files for both runs so I can compare them?

Alternatively, it may just be because the strength is too high. Could you try lowering to 0.65 instead of 0.8 (of course you'll get worse consistency but I'd like to see if it helps the "noise".

Lastly, what are your coherence settings? Any colour correction or optical flow?

I have returned the version of deforum to the previous version, the same parameter configuration, strength: 0.8, there is no noise problem at present, I think it may be the problem of the new version of deforum.

Good job for figuring that out. I will close this ticket because it doesn't sound related to Parseq.

As a sidenote: often this kind of "regression" between versions of Deforum is simply because some parameter's default value has changed. I recommend diffing the settings.txt from a good and bad run to see if there's a simple explanation. This way you don't have to stay stuck on an old version.
