Ok I just tried doing that but all it gives me after right click, more info is the date the file was last opened. It won’t open in Quicktime. It says, “you may need to install different software to play this file”
No I dont know the codec but I know I never installed anything extra when I had Express installed on my other mac. After I posted the first post I installed that exact same copy of Final Cut Express on this new computer and tried the files but they still don’t open.
