Old iMovie
I have a bunch of iMovies I'm trying to watch from 2011,2012,2013,2014 and i can't watch them in 2017 iMovie. is there any other way I can watch these???? I attached pics of the message it gives me and what the files look like.
What is the format of your data backup external drive? Do a Command-Get Info on it.
Do you have a Time Machine back-up covering the time frame of these old videos?
