Finding Ideal Tempo for a Video Scoring Session

Dear Composers:

Whilst fiddling around with sync and tempos, I've found a way to find an ideal tempo for a project that doesn't incorporate tempo changes. Use this formula:

(S/C)60=Ideal tempo

S=seconds C=cuts

For example, a video is 180 seconds long, and has 85 edits.

(180/85)60=127

So the tempo at which the average "beat" of the film and the beats of the music will synchronize the most is 127 BPM. Futz with it, of course to your liking, and use it as a starting point for a project to see how down and upbeats line up with scene cuts. And always go with your ear/eyes, etc.

Thoughts? Opinions?
