gollark: I see.
gollark: Also, if you want to take specific slices out of videos or whatever, use `-c copy` so it can just copy the encoded frames instead of reencoding them.
gollark: Er, why are you doing `. add.sh` instead of `./add.sh`?
gollark: At least this way it is (can be) automated!
gollark: Possibly, depends what it is, I have lots of free time now and can program python a bit.
