Just because something was last updated last year doesn't mean they aren't up-to-date. Not all software need constant updating. It's an illusion that software must be updated constantly. If it's feature complete and there are no known issues with it why bother.
Kdenlive is software I've seen recommended for video editing.
If the device says it's a generic storage device (to the system that is) but actually isn't (based on your description) then it's 100% devices fault and not a Linux fault.
