I wouldn’t hold out hope for decent quality JPEG images given what you are
working with, but I would start with capable video editing software, and then
make individual frame captures.

any decent video player can export individual frames.

there are also automated tools that create screenshots at predetermined
intervals and you get whatever happened at those timecodes, regardless
if it's visually interesting, such as dark frames after a fadeout.

I'd start with VLC as a very solid free example. Check the help files
and print off a list of the hotkeys. They are not always very intuitive,
but they are very comprehensive.

VLC works for me when the other apps won't.

If you're willing to use a command-line tool, you could do this with
FFmpeg [1]:

ffmpeg -i movie.mp4 -r 1 frame%03d.jpeg

That will extract one frame every second and save the resulting files as
frame001.jpeg, frame002.jpeg, and so on. If you want to extract *every*
frame then omit the "-r 1" part.

Hope this helps,

vlc is one of the most unintuitive, poorly designed and buggiest apps.
it can't even scrub without dropping frames. it's hard to imagine that
anything could be worse, but apparently there is.
