I have to attach copy so that it looks like it is embedded on the strings of a tennis racket in mid swing. Is there an easier way other than to make the text 3D and simply line it up frame by frame? The position would be easy with a tracker but I'm not sure about the size and angle in 3d space?
Thank you
Joe

From your description, mocha-AE should be adequate for the task.

Without looking at the shot it's hard to say if either 2D or 3D tracking will provide the solution. For 3D object tracking, you will need mochaAE/mochaPro V3 (V3 requires an upgrade from the version of mocha that is bundled with AE).

Here are examples and tutorials on 3D object tracking with mochaAE/mochaPro V3 -

Thanks for both responses... I wish there was other options other than Mocha. The racket is proving very difficult to track..

[Joseph farina] " The racket is proving very difficult to track.."

You won't be able to receive any worthwhile assistance with such a cryptic description of your issue. You'll do much better if you do the following -
1) post the original clip
2) post the tracking result you obtained from mocha
3) post a screencap of mocha's Parameter and Canvas (ensure that the tracking spline(s) is visible) areas

Cheers
