Hi
I am trying to beat sync some clips of dancing to my music (playing in Ableton). I have set BPM Clip sync to "rate" in preferences.
As far as I understood it the "Rate" method worked by matching the video clip to the nearest 1 bar, or 2 bars, or 4 bars etc
I have a tune playing at 84bpm (2.85 seconds/bar) and a 5 second video clip that is 2 bars worth of dancing, CellDNA keeps playing this clip as if it were 1 bars length unless I press the "Slow" button, which I do not want to do.
I also tried time stretching the clip by 200% in After Effects so it is 10 seconds long - CellDNA still plays it as one bar.
I tried time stretching by 400% to 20 seconds long and CellDNA plays it as 4 bars in length.
Is there nothing I can do to get this clip to play as a 2 bar clip?
It would be great if you could add some way of defining the length of individual clips in bars length so that they beat match quickly and easily
I hope there is some answer to this rather annoying behaviour
Thanks
Piers

I think I'm regretting buying this software, this utter lack of support is appalling
Here's how BPM Rate sync works. We assume a 4/4 signature. First we get the seconds/measure value:
Greater than 4? No.
Hi Peter
Thanks for getting back to me. My brain is a bit too frazzled this evening to take all that in, but I shall have a look at it and see if I can get a value that gets this to work for me.
I have been hard at programming a vj set to be controlled completely by Ableton Live, I have discovered a few issues that make total automation via midi and max4live very difficult.
I have been having an issue where the "More Controls" FX #1 knob has mapped itself to the start and stop controls of Ableton and I can't seem to unmap it, I really wanted it on Ch1 cc41. Is there another way I can unmap this apart from hitting backspace on that knob in learn mode? (which doesn't clear it)
Another feature I am struggling with is the toggle nature of switches when assigned to midi continuous controllers. For instance, I can never be sure whether I am switching the top mask on or off, it is utterly dependent on the state it was last in, I would really like to be able to send 127 and know I am switching it on and to send 0 to know that I am switching it off

Hi Peter
I've just had another thought about the tempo matching clips issue.
If the length of the clip in bars (assuming 4/4) was part of the filename of the video clip, perhaps at the end preceded by a special character or word to signify that there was a bar length declaration
eg DancersClip1%bar%2
where %bar% signifies the declaration of 2
If the filename doesn't have %bar% in it you do the BPM rate your way, if it does have %bar% then the calculation of the rate adjustment is really simple
where y=length of clip in bars ie the value following %bar%
and t=length of the clip in seconds
then the rate adjustment factor = (t x bpm)/240y
Which is a really simple calculation.
Just a thought

Hi Peter
First calculations indicate that I'm unlikely ever to be able utilise 2 bar clips however much I timestretch them to try to fool your system, which is a bit of a limitation.
Thinking more about the solution I proposed could add the length of the clip in bars at end of filename between square brackets eg DanceClip1[2].mov

I keep coming back here most days in the foolish hope that someone from Livid has replied to my post, I think I may be wasting my time!
