  Offset time of value referenced from other comp?

  Posted by David Gruwier on January 6, 2015 at 12:40 pm

  Okay, so I have several precomps inside a main comp. In the main comp, I have a null that needs to control the camera motion inside all the nested precomps. So I made this:
  comp(“MasterComp”).layer(“CameraMovementNull”).transform.position;

  It doesn’t account for the time offset of the nested precomp though, meaning that a precomp starting 20 seconds into the main comp, will get the camera movement from the very beginning of the main comp. Is there a way to compensate for this? Either manually or automatically?

  You can use the startTime of the precomp layer in the main comp, like this:

  C = comp(“MasterComp”);
  ctrl = C.layer(“CameraMovementNull”).transform.position;
  L = C.layer(thisComp.name);
  ctrl.valueAtTime(time+L.startTime)

  That works, thanks!
