Gentoo.
I found an overlay that contains a Gentoo ebuild for shotcut, but I
haven't tried to biuld shotcut yet.

It does now. :)
I've come up with a recipe for what I want to do:
melt \
-producer noise out=100 -attach volume gain=0 -attach gamma gamma=0 \
infile1.mp4 \
-mix 100 -mixer luma -mixer mix:-1 \
-producer noise out=100 -attach volume gain=0 -attach gamma gamma=0 \
-mix 100 -mixer luma -mixer mix:-1 \
[... repeat with infile2,3,4 etc]
I like this better than my previous solution of actually generating an
mp4 file containing black/silence, but it still has a bit of smell to
it.
Is there a better way to generate black/silence -- or just to fade
to/from black silence?
It looks like I could use -transition and ramp gamma and audio gain to
do the same thing, but then (AFAICT) I need to know the frame numbers
where I want to start/end the fade out.
Can you somehow index back from the end of a clip (e.g. frame 1 is the
first frame; frame 2 is the second frame; frame -1 is the last frame,
frame -2 is the frame before the last frame). Then transitions could
be applied to the end of a clip without having to know how long it is.
All the examples I find of applying a transition to the end of a clip
require knowing how long it is.
