Random cuts to keyframes

[Mark Allen]

I’m not a scripting guru – but I think basically what you’re asking is how to script this:

in your main comp you have an audio file and a sub comp

in the sub comp you have a bunch of stills – one each frame.

everytime the audio reaches a certain threshold, then trigger to move to the next frame using time remapping.

Thank´s but not really.
I know an expression for random stills from motionscripts.com but what I would like to do is let the audio keyframes trigger the stills.
