  Syncing “Edits” to Comp Markers

  Posted by Matt Miller on March 9, 2016 at 9:21 pm

  I do a lot of animated lyric videos that require marking lots of text in/out points. This is always quite a tedious process, and often requires me to go back and adjust a lot of in/out points manually. I wanted to see if there was a way to link the in/out points of a layer to a comp marker, but as far as I can tell there isn’t. However, I was able to modify some existing expressions that I found on the web to suite my needs.

  The expression uses the layer order to “link” the opacity value of a layer to the comp markers in order. So for instance, the topmost layer will turn “on” at comp marker 1 and stay on until comp marker 2. Then at comp marker 2 the second layer down will turn on and will stay on until comp marker 3. And so on. Anyways I know this is a pretty simple expression but it’s going to save me a lot of time and hopefully someone else finds it useful too.

  if (thisComp.marker.key(thisLayer.index).time < time && thisComp.marker.key(thisLayer.index+1).time > time) {100} else {0}
