.mov just sound no video showing
My drive space was full on my iPhone, so transferred files to my hard drive. However, great % of these files are showing a default pic of the file, not an actual clip of what the video might contain. And, when played it only provides the sound and no video. I've tried opening these with QuickTime and other sources, but just sound. Are all of these family videos corrupted?
iPhone 8, iOS 12
