92bpm with 12fps is not that good a combination
Basically what you have to do is divide the bpm by the fps,
and it tells you the number of beats per frame - which in your case
will end up in sth like 7.6 meaning you have 7.6 beats per frame.
In your case (if possible) you could go for 11.5 fps, which
makes 8 beats per frame. Better though (I think) would be to pitch
shift the music up to 96bpm. Then you would also have 8 beats per
frame with 2 bars per frame.
