  Time remap trigger opacity

  Posted by Igor Stikic on July 30, 2013 at 9:23 am

  Hi,

  I have a problem and need help. I have a composition (Trigger Color) with time remap hold keyframes that uses two alternately values ​​of 0;00;00;00 and 0; 00;01;15 Above that I have 2 layers (Color 1, Color 2). What expression set opacity of (Color 1) to 100% when the time remap of (Trigger Color) is 00;00 and 0% for else. (Color 2) same but for the time 01;15

  Thanx in advance

  for Color1 opacity:

  trigProp = thisComp.layer(“Trigger Color”).timeRemap;
  if (trigProp.numKeys<1) value
  else (trigProp.value == trigProp.key(1).value) ? 100 : 0;

  for Color2 opacity:
  trigProp = thisComp.layer(“Trigger Color”).timeRemap;
  if (trigProp.numKeys<2) value
  else (trigProp.value == trigProp.key(2).value) ? 100 : 0;
