On this here video for example, you can see that the resulting video has a repeating frame every 4-5 frames, implying that it was originally 24fps rather than the 30fps used in the end result.
Removing the repeating frames not only makes the end result smoother but it also will make your processing and render time shorter by virtue of there simply being fewer frames to process. It will also theoretically make the final video a bit higher quality since the resulting bitrate can be allocated across fewer frames, increasing the fidelity of each individual frame, but I say theoretically because this may be a small enough difference to not actually notice.
So yeah, I really like this video (though I can't help but wonder what this "blonde teen Repunzel" would look like with big tits and/or as a tranny), but I'd love to see a "fixed" version without the telecine judder.
For this reason, it really is ideal to do this before doing the deepfake processing step, but it might be too late for that.
I typically use the relatively simple video editor "Avidemux" - after opening a video in that program, you can use the left and right arrow keys to move one frame at a time, at which point it should becomes very easy to see if there are any repeating frames and if they are in a consistent pattern.
From there, you can re-encode the video to whatever (x264, hevc, even lossless huffyuv) and then click "filter" and look for the "Resample FPS" filter and double-click on it, note the value that it currently lists (that's the current framerate rounded up to 2 decimal places; if it says 23.98 then it's actually almost certainly 23.976) and input your desired output frame rate and click "OK". From there you can click "preview" press the > button on-screen to step frame by frame to confirm that the repeating frames are eliminated.
Regarding the framerate to choose for the "Resample FPS" filter, there's a relatively simple math equation to figure out what the end resulting frame rate needs to be.
([source frame rate] / [frequency of repeating frame]) x ([frequency of repeating frame] - 1) = desired frame rate
So if the source is 29.97 and every 5th frame is a repeat of the frame just before it, then the equation looks like this:
(29.97/5) * (5 - 1) = 23.976
aka:
5.994 x 4 = 23.976
I hope this helps; this is the sort of thing that does require a bit of general know-how in terms of video encoding.
