a lot of times editors will cut picture to music, and the person who wrote the music composed to the cuts ( chicken and egg sort of thing) so using the same tempo as the original music is not a bad idea, as all your "hits" will line up with the spot. as far as frame rate, i feel like 29.97 is pretty standard, most audio programs seem to like dv's. another web site to check out is wheresspot.com. also doing music for student films is another way to get experience scoring to picture, and make a little cash while your learning
. good luck!
