RE: Question about page break time indices

[Dirk Klamer]

Carl,

Use the the bar numbers and the timing of a single (average) bar duration to
calculate the time somewhere in the music
Is this a option?

Kind regards, Dirk

Subject: Question about page break time indices

All,

I am involved in some choral 
recording projects where we are 
having the singers sing from 
projected slides. To aid in timing, 
pitch, etc., we have it set up where 
they have headphones feeding them the 
MIDI of the song being recorded as 
they sing. All of this is synchonored 
through the recording software, with 
the slides being pre-rendered to a 
video file.

Right now, the music slides are being 
created in Finale (cringe), the MIDI 
is being manually input into the 
recording software because we've had 
issues with Finale's MIDI being 
accurate on tempo changes, and I am 
using Apple Keynote to render the 
slides to video using manual timings.

I would like to use Lilypond to 
render the individual slides and the 
MIDI, then use ffmpeg and some other 
things to programmatically render the 
video itself. The issue is that in 
order to do that, I need accurate 
timing information on slide changes.

Which gets to my question/request. Is 
there a way, when Lilypond is 
running, for it to output some sort 
of auxiliary file with some kind of 
tick/time code information about each 
page? In other words, what is the 
time index of the first note on a 
given slide/page? With this, I can 
work with scripting tools to work 
backwards from each time code to 
generate the still images for the 
transitions from slide to slide.

Thanks,
Carl
