What I am working on are tools for composing audio to someone else's video.   I've worked on a couple projects like this, I am in the midst of one know.  Basically, think sound design for a movie and things like it.  They generate the movie, and so far, I have found the easiest way to communicate with the people making the video is to use frame numbers.

Therefore, to compose my sound, I need to frame numbers as a reference.  Therefore, I need to generate line data from video frame numbers, unless someone has a better idea.  If the video guys tell me, "this animation starts on frame 1234 and ends on 1623", then it seems to me that I want to be using frame numbers as my triggers.

Cyrille points out the correct method of syncing video to an audio clock.  All hardware devices and professional software use the audio to clock the video.

hello,

i'm wondering why did you sync audio on video : i think it is easier to sync the video on the audio.
just make all the line~ as you wish for the audio, then snapshot~ periodically and convert audio position to frame number...
