I'd like to be able to examine videos very closely, frame by frame. Is there a program that would allow me to easily do something like this?:
1. Show the first frame for 3 seconds
2. Jump forward by 10 frames
3. Pause for 3 seconds
4. Jump forward by 10 frames
5. Pause for 3 seconds
6. And so on...
Although I'd prefer to use a Linux program to do this, I will consider Windows (freeware) programs as well.

Re: Very slow video playback required
I don't know of any program that can automatically perform those steps you describe, though you may be able to script that action for one. Most players can slow down playback to where they are going frame by frame, and then you can pause to examine one that catches your interest. I I know SMPlayer will allow you to advance frame by frame also. Perhaps the Avidemux video editor will also allow you to do this--it does have a control that allows you to advance and rewind at will. Avidemux has an Appimage, since it's not in the Debian repos, and you have to be careful about adding anything from the deb-multimedia repo.

Pretty fun, play with this?
rate .00000000001 seems to be around 1 sec, don't know how low it goes? Don't different formats have different fps? Not sure how you could calculate exactly ten frames every 3 sec.
Code: Select all
$ vlc --antiflicker-softening-size 10 --rate .025 Lews\ Mach\ II\ Speed\ Spin\ Series.mp4

Frame by frame in the digital world? How does that work? In the days of film movies were made by taking a series of pictures and playing them back frame by frame (hence the term movie). Does digital mimic that?
As to the OP's question, slowing down playback and hitting pause is probably what he will end up doing.

For example, if you have some individual frames named image_x.png (where x is a number) then you can use this to make a movie from them:
Code: Select all
ffmpeg -i image_%d.png movie.mp4
