I am creating a multi layered credit title sequence using Comp Lab Pro. The top layer will be a shot of each actor in turn. The shots are masked so that the video appears as photograph overlaid on the background tracks.

What I want to do is to create a drop shadow effect behind the top layer. I was thinking that I could copy the masked image, colour it completely black then off set it by a few pixels from the matted image of the actor.

Not so difficult so far but the top image isn't stationary. To make the title sequence more interesting the matte changes size/shape/position over time so the drop shadow would need to move/alter shape as well. Does anyone have any ideas how to do this (other than going through frame by frame?)

You can copy the animation from one object to another. So create the animation of the top layer, then copy it to the drop shadow object.

After that, go to the drop shadow object's animation toolset and to the first keyframe, hold down Ctrl and drag the origin so it is offset from the top layer. Holding down Ctrl means that all the other keyframes will be updated in the same way - ie, they'll all be offset by the same amount, while still following the original animation path.

Thank you, that's excellent. It's great the way you are always one step ahead of what a user might want to do with the programs and have designed in features that we haven't even realised we wanted yet!.

UPDATE - worked an absolute dream!
