Can iMovie Libraries be safely stored on iCloud Drive
So, I'm trying to finally make some sense of my iMovie Libraries. I'm also trying to organize them (see previous question) and favorite them successfully and just emerge with something that makes sense and is not unorganized chaos.
But I've got three laptops and a bunch of legacy iMovie Libraries. One is running Mojave (I cannot upgrade because I need it for 32-bit VST/AU plugins and for 32-bit music apps), the others are running macOS Ventura and macOS Monterey.
Would the best solution be to store the iMovie Libraries generated with all of these devices, on iCloud Drive, so that they'd be easily accessible to me on all devices?
Will I run into compatibility issues between Mojave / Monterey / Ventura? I'd prefer to continue my work on all devices, since they all have different files and I cannot sync them easily.
In fact, I wish there was an easier way of sorting and organizing files, something more Apple-like, because my files are all over the place on USB-sticks, external harddrives, SD-cards, iCloud Drive and elsewhere.
So just the basic question is, are iMovie Libraries safe on iCloud Drive? Or will they be unusable after saving them to iCloud Drive - i.e. do I risk dataloss?
