QuickTime & iMovie Can't Read 64 Bit Files

Hello everyone,

I'm trying to view MOV files from a Panasonic GH5 Lumix camera and having no luck. It appears this is due to the fact that my current version of the apps only read 32 bit files, and the camera is 64. And this despite my using the latest Mojave OS. What gives? Any ideas how to fix this? Thanks!
