I am trying to create a clip where an large alien walks behind a hedge.
Shown here:
I have motion tracked the clip so that the alien follows the camera movement, and now I need to make the alien walk along the hedge. my plan was to simply animate the layer with the alien on it along the hedge, however, when I do this, the motion tracking disappears. Any suggestions on how to do this would be appreciated! Thanks in advance!

If you trying to track and animate on the same layer shouldn't work because because you already have keys tracked for position. You would need to set the track on a null or another layer then parent the alien to track layer so it sits in place. Then you can animate the alien's position with out effecting the track.

However if your simply saying you track is disappearing then maybe you didn't actually apply the track to a layer.

hope that helps somewhat

Thanks for the help. A null layer was exactly what I needed to use!

...and happy rotoscoping; I presume those legs go BEHIND the shrubs.
