Synaptic, re kdenlive: "Depends: libmlt4 but it is not installable" I looked at cheese some time ago, and was confused. I'll take another look.
According to Google, guvcview is supposed to do what I'd like, but it makes a pretty picture, and somehow--not sure how, since the save command
is sporadic---saves it, but I can't figure out how you're supposed to play it back, so I don't know what the result was.
Googled for instructions for the GUI, but only found reference to a command-line interface via a man page that might as well be written in Greek.
I would appreciate being sent to a user manual for guvcview (GUI) if there is one.
Thanks for looking. BTW, I think the original file name was kamoso, with an "s" but it doesn't matter now.
