Okay, I think I have negotiated a defensible truce with Kdenlive.

I am manually editing the documentid property in the files, to give them unique numbers:

777 = prefix for Lunatics, so I know it's one of mine
01 = "series 1"
01 = "episode 1"
0n = scene sequence number (TR=01 ... SF=07)
(00 for top level, 11 for end credits, main credits get a library #)
nn = role-based: 01 main, 02 sync, 11 desc audio, 2x for BTS extras

And THEN I am deleting the "storagefolder" property, because it isn't necessary. I don't see any way to do this in the GUI (the obvious thing, to set the radio button to "default" does not do it), so I'm just doing it in the file. Apparently, if you never changed the cache folder, this property is never added, and it seems to work fine to delete it.

That seems like the best option for portability, because it won't hard-code my own directory structure.

It does seem to be hard-coded, though -- it doesn't use the default location I set in the Kdenlive settings, but always $HOME/.cache/kdenlive.

But it'll do. #Kdenlive #Cachefiles
