  x movement using marks

  Posted by Marcelo Cabral on March 14, 2013 at 4:22 pm

  Hi
  I am using this expression which moves a 3D layer in the z position.
  As you will see this expression us the inPoint and the outPoit to start and stop the movement. What I am looking for is the way this script works using mark in other layer called CONTROL. I mean first mark will remplace the inPonit and the second mark will remplace the outPoint.
  Any help will really help me because today is the deadline project

  zmove=-300;
pos1=value;pos2=add(value,[0,0,zmove]);
linear(time,inPoint,outPoint,pos1,pos2)

  Something like this:

  
m = thisComp.layer("CONTROL").marker;
zmove=-300;
if (m.numKeys > 1){
t1 = m.key(1).time;
t2 = m.key(2).time;
z = linear(time,t1,t2,0,zmove);
value + [0,0,z]
}else
value
