I'm still using Mojave 10.14.6 and want to be sure that the movie files I have will open in Catalina. If I can open .mov and .dv files now both in the Finder and in iMovie will I be able to open and edit them in iMovie in Catalina?
You might want to take a look at this about what to do to media files before upgrading to Catalina -- https://support.apple.com/en-us/HT209029
