I suppose that makes sense given that information is encoded as a series of key frames interspersed by 'I-frames" that simply encode the delta to the previous key-frame when using most compressed video algorithms. So cutting in-between key-frames doesn’t really make sense since the I-frame would no longer have anything to reference it’s delta to.

Ooh nice! Did you have any issues working with the Katalox? I just got some and it’s so hard it feels like tile!

It’s worth noting that the job of auto-mounting a removable drive is often hidden behind the popular file managers, if you want to do it without one you are probably looking for the “udiskie” application that does this in a more agonistic/generic sense. https://github.com/coldfix/udiskie. With that running in the background to automount, then you can just access the drives from their auto mountpoints in the default location of /run/media/username/drive_label
