It's a well-known technique in astronomy, eg https://www.aanda.org/articles/aa/ps/2005/22/aa2320-04.ps.gz

For anyone put off by the .ps.gz, it's actually just a normal web page that links to the full article in HTML and PDF. Not sure what they were thinking with that URL. I almost didn't bother to look. (Maybe that's what they were thinking?)

I seem to remember from my computer vision class way back when that there's a fundamental theoretical limit to the amount of detail you can get out of a moving sequence. Recovering frequencies a little higher than the pixel sampling is definitely possible, but I feel like it was maybe something like 10x theoretical maximum. I also get the feeling, from looking around at available software, that in practice achieving 2-3x is the most you can get in ideal conditions, and most video is far from ideal.
