keynote stopped playing avi files
At some point recently Keynote (version 10.1 (6913)) stopped playing movies that had previously played. I'm running Catalina 10.15.6. The movie files are .avi which I know can cause issues, but they played before no problem AND if i share the file with others, they can play the movies, so it's specific to my laptop and my version of keynote. Any ideas? thanks!
