element 3d text help

The first thing I would do is pre-compose the shot you are trying to track and get it in a sperate comp. It looks like you are trying to use as an NLE.

Depending on what the camera does you might think about Camera Tracking. Set up an origin and ground plane, then add a camera and a placeholder solid. You could then export that scene as a C4D file and extrude your text using C4D lite or you could the scene data in conjunction with Element 3D. If we could see the modified properties of the layers you are having problems with (press the U key twice) we could probably give you some better suggestions. Element 3D can be confusing so you'll need to spend some time with Video Copilot to get a handle on how to use it.

The other option would be to Stabilize Motion, add the extruded text, then put the motion back in the shot and add it to the text layer. Without seeing the actual shot I can't tell which approach would be the most efficient.

There is even another option which would be to motion track in Mocha AE and use some advanced corner pin techniques.

If you are new to motion tracking I suggest that you check out the help files by using the Search Help feature at the top right corner of AE. Search Camera Track, then search motion track.

Show us he clip and we'll be able to help you figure out the best approach.
