Amy,
Recently I made a single-line scrolling video using LilyPond. Take a
look at this monster... nobody else has yet :)

I had LilyPond output the whole thing as a single .png image. The image
is so wide (60635 x 1082) that it immediately crashes utilities like
ImageMagick. However, Gimp works on it.
I used this in the the .ly file:
\paper {
line-width = 600\in
left-margin = 0.25\in
right-margin = 0.25\in
check-consistency = ##f
page-count = 1
indent = #0
ragged-last-bottom = ##f
ragged-right = ##f
ragged-last = ##f
}
\header {
tagline = ##f
}
#(set-global-staff-size 69)
and used the command:
lilypond -dbackend=eps -dno-gs-load-fonts -dinclude-eps-fonts
-dpixmap-format=pngalpha --png Merry_Go.ly
Then I had a Python script to extract a sliding window of sub-images
from the png and add background, used ffmpeg and other tools -- one
filthy hack after another.
It looks like I maybe should have used 60Hz framerate instead of 30Hz.
Regards,
Curt

Dear list members,
although I'm a veteran user since 1.6.6, I've just come across a problem
that I can't solve on my own and I can't believe it hasn't been
implemented yet. I'm trying to get Lilypond to output the music (just a
regular piano piece) on one long line, i.e. as if on an endless long
paper strip. The reason is that I'd like to let the notes scroll along
on a video screen while the music is being played so the viewer's eyes
can always stay in the middle of the screen.
Do you know what I mean? And does anybody know how to do it?
Kind regards,
Amy
