Extract Frames from Video — PNG & JPG Sequences

A 30 fps video does not have to give you 30 images per second. The extractor seeks to evenly spaced timestamps at whatever rate you ask for, so 2 fps gives you a contact sheet and 30 fps gives you approximately every frame.

Because it works by seeking rather than decoding the stream linearly, timestamps land on the nearest available frame. For most codecs that is exact; for heavily compressed footage with sparse keyframes, two adjacent samples can occasionally resolve to the same source frame.

PNG is lossless and keeps alpha, which makes it correct for anything that will be edited again — compositing, rotoscoping, or frames destined for another encoder. It is also the largest.

JPG at 85–92% quality is a third of the size and fine for reference boards, thumbnails and anything a human will look at once. WebP splits the difference and keeps transparency, but check that whatever you are importing into accepts it.
