you nailed it! very nice and with your comment next to it I almost understand the entire process.

thanks a lot, this is far more complicated than I expected and probably never would have gotten this result!

if I find some time tonight I’m gonna try to put an overwrite command in it, so when the animation is playing and the ‘beat’ reaches the treshold again it will start from frame 0. But that’s the next step, this is already exactly what I needed!

ps. I come from a flash background (years ago) so I’m still thinking in frames+language in an actionscript kinda way 🙂

[Marcel Ooms]

A new idea is just add a slider, and add expression:

numberFrames=60 //frames animation lenght
l = 60/numberFrames
numberCycles = Math.floor(time*l)
i=numberCycles/l;
f= time-i;
f

and find the loop or regular beat and use the slider for all the irregular beats, but the only reason for this solution is because i really can’t get your script to work or have any more ideas

why doesn’t AE have any kind of expression memory instead of the everyframe check!!!! 🙁

Hey walter,

Thanks for your help. I figured out that I had to convert them back, but still the value switched back to its original value as soon as it hits the frame after (in this example) 55. But i’ve got the feeling we are getting there.

I also tried a different way today. Just copying the animated layer and offsetting it start to everytime the layer hits 55, but this asked for a script i guess, which is even harder (if you’re not the programming genius like me). so that plan failed 🙂

it’s really strange that after effects hasn’t got an expression like ‘nextFrame()’ or something, so you can get the value back to 0 and then say ‘nextFrame(till frame 20)’

[Marcel Ooms]

Indeed I was hoping for some kind of memory instead of a everyframe check.

The animation is about 10 frames long and the beat too. Can you program something like: when hit 55, play 10 frames. I’m not sure how it works with your second paragraph, but indeed it would be a way to say: play frame 0 when hits 55, thereafter 1 thereafter 2 then 3…. etc, in some way hardcoded instead of just (cycle)

yes it is possible to just set a comp for every beat. But we want o automate it, so with 10 music layers, 2 minutes and at the end even switch the song so we get an totally different animation but with the same elements.

so audition wouldn’t work, because we want to make it applicable for every songs (of course with a little bit of tweeking in the AE file) without changing the song

[Marcel Ooms]

that’s a start! thanks. But it is an irregular beat.

so far I have:

t=value;
if(thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”) > 55)
{
t = 0
loopOut(“cycle”)
}

t

but now it won’t run the cycle. When the beats hits 55 it return to 0 (as I want it too) but then I want it to play at normal speed, so timeremap should just be 0 en continue.

instead, because of the t=value, the frame after the beat hits 55 it return to it’s original value. So how do I make a value, which at the beginning just gives the normal framerate, but I can tell “when you hit the beat, value = 0 and start over”

[Marcel Ooms]

in flash language (which doesn’t work with timeremap:D)I would say:

if (thisComp.layer(“Audio Amplitude”).effect(“Both Channels”)(“Slider”) > 50)
{
play(once);
}

Can you please upload the file once again, because it is exactly what I need but I can download ‘impossible.aep’ anymore 😀

thanx in advance

[Marcel Ooms]

I do not completely understand it, but it works! so thank a mega lot 🙂

[Marcel Ooms]

I found what is weird about this: scale is in percentage, so it is a relative value. So what I’m asking is a absolute percentage….

I’m starting to doubt if this is possible, although it seems like a pretty common thing to ask.

Maybe a giant expression of 100*(percentage null1)*(percentage null2)…. etc is a solution? Or will I get weird values when taking percentages from percentages?

[Marcel Ooms]

I’ve got some kind of the same question. What if the edit is done on mac (final cut pro) and the after effects on windows. Is the best way just to export the files (I heard something about “black magic” codecs to be the best to switch between mac/pc, or is uncompressed the best?).

and the export out of ae, should it be the same codec?

thanx in advance
