  Any way to See Expression Keyframes in the grpah?

  Posted by John Donley on January 1, 2008 at 1:21 am

  I am trying to separate the x,y, and z for the camera position. You cant use the separate xyz script on a camera layer. So I created an null layer separated the xyz on that, then I made the camera a child of the null layer. Now I can set the values of the xyz separately, but I cant see the key-frames in the graph editor. I assume then all key-frames I set will interpolate linearly, which is not good.
  Is there anyway I can make those separate xyz expression key-frames to show up on the graph so I can edit them?

  Hi!

  I recommend that you use your Null only as an Expression Controller. Create 3 Slider Controls (X, Y, and Z) on your Null and name them appropriately.

  Then use this expression in the Camera’s Position:

  X = thisComp.Layer(“Null 1”).effect(“X”)(“Slider”);
  Y = thisComp.Layer(“Null 1”).effect(“Y”)(“Slider”);
  Z = thisComp.Layer(“Null 1”).effect(“Z”)(“Slider”);

  (X, Y, Z)

  After you put that expression in, you can keyframe the slider controls on the Null object and see them in the timeline by pressing “u” on the keyboard.

  Let me know if that wasn’t what you were looking for!
