Hi,
I have the free trial version of Logic Pro X which is 10.5.0 and today I opened my project only to find that the movie wasn't playing. It's a mov file. I tried converting it to mp4 and it didn't work either. It only shows a black screen. It never happened before. Some other movies (not all of them) do show up, but I can't figure out why.
Also, it's a movie without audio, if you wondered if the movie audio played or not.
