Heres a good one.

How do I generate a hash that allows me to compare a re-encoded video against the original to verify they are the same so I don't end up with weird gotchas like this length = that length and this filename = that filename

since the file sizes will be completely different ?

It depends quite a bit on your choice of technology and how much time you're willing to put into it, but I think these (somewhat old) presentations provide good theory, pointers, and sources on how to do something like that:

And this project to identify a video clip in another (YouTube) video might do the job or at least be helpful in how to make it do what you're aiming for: https://github.com/bergkvist/...

@Flygger i'll look ty
mathematically you understand the validity as well :P

I don't think just doing a frame by frame resize would work and comparing because the method of doing so in one lib would differ and the frame rate might vary.

heres another good one.
same idiot showing up commenting on how bread, dill cheese, apricots and soda is a strange meal.

you know it bothers me that there was a nice period of pretty ass and titties and suddenly i'm surrounded by frog eyed chomos.

how the hell did that happen exactly ?

still trying to figure that one out.

example the show good omens as commented on over 10 to 15 years or however long its been and ago.

eve had the most beautiful ass i've ever seen on a dark woman and that was par for the course.

wtf happened ?

I hate to ruin your idea , but isn't this what sites like YouTube and Facebook are spending millions on so they can detect copyright infringement?

@ReverendLovejoy yes but I thought of a way that is simpler

And probably not 100%

@ReverendLovejoy meanwhile blow me killjoy
