A few months ago, I was able to analyse my MPEG clips, now for some reason, it doesn't work. Out of curiosity, I made a quick video in Photo Booth and that worked fine. I then converted an MPEG to an MOV and that worked fine too.
I realize I sort of found the solution to my own problem but there has to be a way to make MPEG clips work. Right? Three months ago, it worked fine. What changed?
