Is there a program that allows me to pass in a video and capture the screen at every n frames? For example maybe I want to export screenshots at 24 frames per second from point A to point B, so the program will be exporting 24 images per second. The amount of frames I would like to capture can be specified (maybe I only want 1 fps, maybe 10 fps, maybe 24, 30, 60, ..)

Preferably, it would be part of a larger program that supports various video formats. At least, it should support the more common formats out there.
