Hi,

I was wondering if anyone knows what the exact tempo a song should be so that I could do a seemless, exactly on the bar edit in an AvidDV editing system? What would 24FPS or 25FPS match up to tempo-wise on a sequencer? With say 1 or 2 seconds being a bar? I know it would be a hell of a lot easier to cut a track down in sound forge or something like that but... it would be something interesting to know. (and I can't find a calculator!!)

Cheers,
s

huh what? do refrase... whats frames got to do with it? 24 or 25 frames is one second... 120bpm has 2 beats in one second, 180 has tree etc etc... what are you asking?

if you want 1 second per bar and assuming 4 beats to a bar and 24 fps then that means:

1 second = 1 bar = 24 frames
4 beats/bar ==> 4 beats/second

24 frames/second ==> 24/(4 beats)=6 frames/beat.

so 120bpm ==> 120*6 frames/minute

if you want to use other bpm follow the formula:

BPM*6 = number of frames per minute assuming 24/fps.

I just came up with this now so hope it's right. Is this what you want?

Yep, I think that answered it.

6 frames a beat at 4/4 at 240bpm or
12 frames a beat at 4/4 at 120bpm?

Is that right?

The reason I'm asking is cause in AvidDVXp I can only edit in frames, no smaller, and for the sake of creating audio tracks and sfx outside of Avid to bring into Avid I might as well do it at 'editable' tempo (if its at all practical).

Theres gotta be an easier way to put this question...

yea i think it sounds right. i suspect however, that you may still get some timing issues just like how you can't really synch two sequencers together by simply setting the same bpm and hitting play at the same time (it goes out of synch after awhile).

then again i don't know how video editing works our how software works so maybe there's some bpm->frame synch mechanism that it employs.

write to picture if you ever can. i think it's shocking avid can only edit audio to frames, piece of shit. i was talking about this the other day with a (musician) avid editor, he was like, nah you can do it ok. i'm gonna press him on it monday. ing digidesign

At 60 bpm (MM=60) a quarter note equals one second at 24 0/8 fps.

I'd like to suggest the book "On The Track" which includes a complete click book as an addendum.

The paperback is half the price but I think its one of the few books you'll want to own in hardcover if you plan on pursuing a film score. I can't remember how many time I referred to my copy during my first experience as a music supervisor. A paperback would have fallen apart and ignorance would have been way more expensive.

Hope this helps

this seams rather ridiculous because no composer ever writes their bpm
according to the frame rate. they write to picture and edit accordingly.

usually the music either fades, hits a note that holds for about the last bar and
then fades, or changes the tempo slightly to accommodate the important
hitpoints and/or end of the segment.

Click books seem to have been around a long time though so there must be something to the idea. Sequencers and their ability to map tempo or "edit accordingly" have, as I understand it, pretty much replaced the need for click books on the scoring stage. I really think that anyone interested in the subject should read the book I referenced above. I know it cleared up a good many of my own misconceptions at one time or another.
