  Can you delay a layers start with a slider for use in a MoGRTs?

  Hello,

  I have a sequence with 7 precomps (all the animation happens within each preocomp), can you link each of these precomps to a slider so that the editor can delay the start of each precomp to time it with a voice over in premiere?

  My comp is 25fps, so if they move the slider to ’50’ it would push back the precomp 20 seconds, or 450 for 3 minutes etc..

  Thank you

  Maybe turn on time remapping for the precomps and add a time remap expression like this:

  s = thisComp.layer("Control").effect("Delay 1")("Slider");
  delay = framesToTime(s);
  Math.max(0,valueAtTime(time-delay));

  I do like the quiet confidence in your posts. I know when I’ve found a post with your name it will work!

  Thank you Dan, spot on.

  Is there a line I can add to turn the slider into seconds, so on the slider; 1 = second, 60 represents a minute etc..

  This should work:

  delay = thisComp.layer("Control").effect("Delay 1")("Slider");
  Math.max(0,valueAtTime(time-delay));
