Number of Frames affecting likeness and consistency

[YourAIGen]

Hey standin team,

I have noticed that changing the number of frames for a video that I am testing has an effect on the results e.g. 41 frames character looks more like my input image while 101 frames of the same video same character same parameters, and the output is different, and 161 frames again is different. Is this something that can be resolved in the update?

Additionally, I have also noticed that if I mask a person out and I replace them with a character, after a certain number of frames the output doesn't do replacement anymore. The character basically becomes invisible. For example, at 201 frames, the reference image was replaced into the masked area and I got the output video, but at 202 frames, the output video has no replacement and the masked region was diffused on to blend with the background.

Any thoughts or help with these problems woudl be really appreciated.
