motion tracking keyframes —> camera moves ?
i have been playing around with shooting a really simple “target” handheld and then tracking the motion in AE to give other layers
a look as if they have been shoot handheld. what i would really like to do is transfer that motion ( a series of postion kefyframes on
a layer ) to motion on a camera but it wont let me select a camera as a destination for the motion. is there some way of getting the
handheld data back to a camera in AE ? -

I think others are more camera-savvy than I, but it seems a straightforward copy/paste.

First apply the keyframes to a solid or other layer, then copy them from that layer’s Anchorpoint and psate to the cam’s position.
Apparently you can’t apply the 2D position data directly to the 3D position of the camera from within the Tracker ?
Copy/pasting will convert it by giving each value a Z of 0,
However, this will not correspond to the same plane your cam was in when you created it,
you can compensate by moving your 3D layers further in front of the camera, or:
push all the cam’s keyframes back in Z (negative), by the same amount as your camera’s zoom property: this is the default, a compsized layer at Z position 0 will now fill the screen. -
you can also apply the tracking data to a null and then parenting your camera to it
who is that masked man…
