  Duplicating curve ballistic

  Posted by Kenny Mims on January 4, 2007 at 4:16 pm

  Visualize with me if you will:

  I have two items that must scale at the same rate. Item “A” scales from 30% to 360%. Item “B” scales from 8.8% to 106%.
  (they are scaling by the same factor)

  OK, easy enough… but

  If I want to adjust the ballistic of the action with the curve editor, how do I duplicate the action EXACTLY, only with a different value?

  Perhaps this example will clarify my question:

  Item “A” = a wall with a doorway
  Item “B” = door

  Action = zoom from full screen room (room scale 30%/door scale 8.8%)
  to full screen door (room scale 360%/door scale 106%)

  and… I want to change my action to more exponential so it appears to accelerate.

  and… both item must follow the same exponential curve.

  Thanks

  How about reading the manual? I’m sorry to say so, but you really come off as trying to do your work the lazy man’s way without having even read the first few pages of the AE manual. I strongly suggest to do so before doing your first bold steps in the animation/ compositing/ motion graphics world as at least a basic understanding of keyframing and interpolation behavior is a minimum requirement in any compositing or 3D animation program.

  Ouch there Mylenium,

  Perhaps you didn’t understand my question.

  as it turns out… the solution appears to be to coordinate the motions in linear fashion, then pre-compose all related layers, time re-map and adjust the acceleration/de-acceleration (exponential) curves from there. Then all the x’s & y’s & z’s are all in sync.

  And it’s not really in the manual, but it is in one of these terrific COW tutorials (more or less).

  “Fixing Scaling Issues–Part Two by Aharon Rabinowitz”

  So, thank you COW tutorials!

  Mmh, apologies then, but it really sounded very odd.

  Cheers
