Hi! Seems like a perfectly reasonable request; there are tens of
thousands of packages listed on the Python Package Index, and this
mailing list is one of the best places to find advice!

Are you playing the video in real-time, or is it stored in a file that
you'll end up playing? If the latter, I would recommend looking into
FFMpeg (or its fork AVConv), which has an insane number of features,
and quite likely has what you want. It'll read in a file and write out
a file.

If it's real-time, though, I'm not sure what's best to do. Do you know
exactly what distortion you're trying to perform here?
