Motion Tracking

I am shooting a clip and swapping out the existing billboards with other clips. Would motion tracking work to "attach" the clips or would keyframing be the way to go?

Pete's rotoscoping tutorial is the way to go! Thanks Pete!

Tracking is an automated way of adding keyframes. You'll fine that you probably will do a bit of both. Do a 4 point (Perspective or parallel corner pin) track. I would make a soild the size of the object you want to add and appy the tracking data to that and then parent your real object to the soild I think! There is the choice in the 'edit target menu' of 'apply to effect point' but it was greyed out. Not sure what I had setup wrong there. I have not done a 4 point track since the new (7) version of AE.

BTW I just did the Shake Tutorial on this subject and Shakes tracking setup was great.

I thought that tut was great too, but if you're changing perspective you might want to look at these:

Keep motion in perspective

Using the new Motion Tracker

And this if part of your track leaves the screen:

And 5 min into Aharon's tut is how to manually fix a cranky track
