Ah, gotcha.

How would I go= about scaling the amplitude of the motion so if it moves 200px on the trac= ked layer, it moves only 50px on the child layer?

Hi Jarret,
You can change the p= arents centre (anchor point), to match your layer's position! =A0That&#= 39;s what I meant by "Offsetting".
Cheers, Rob


Hi Robert,=A0I'm afrai= d I don't understand what you mean you by "offset". Also, the= layer would then use the parent null as the centre of rotation which would= look odd.

Hi J,Apply the tracked data to a null, then parent your layer to it with an of= fset for position.

Hi everyone

I feel a bit silly asking this here but my brain seems = to have turned to mush and I'm having trouble thinking this one through= .

I've tracked a handheld camera shot and now = want to apply that tracking data to the layers in one of my comps, layers w= hich already have animation data associated with them for position and rota= tion. What would be the easiest way to:
  1. apply the tracked animation data to the layers in the comp
  2. scale the amplitude of the tracked position and rotation data as it is= too severe
Many thanks for any help.
