Older .MOV videos not playing on QuickTime and when converting to MP4 via handbrake, VPL etc they become still pictures
Hi I have a lot of family videos that were filmed on older iPhones (2008-2014) in the .MOV format. I know this is no longer compatible for Quicktime and they need to be re-coded or converted. I have tried this through so many third party providers (handbrake, VPL etc) and they just convert to a still picture. For example a movie might be 575kb, but it does not show any length of time.
How can I recover these these family videos and watch them? Can I get an old version of QuickTime?
