Everyone keeps mentioning vfr and cfr. I know what vfr and cfr mean but
I don't see how that has anything to do with my issue, because I'm not
creating a video as output. I'm only creating images for every frame in
the input. So, can someone explain why this matters?
I understand the fact that if the output is cfr and the input is vfr, then
some frames may need to be duplicated or dropped. But if the output is
merely a sequence of images, why does this matter? There's no frame rate
in a sequence of images,
