Hi

I work with an interactive After Effect / Flash project. I have made a movie in AE with people holding billboards etc onto which interactive data is going to be projected with Flash.

I have tracked my billboards with the Corner Pin Perspective tracker. Problem is, that when I apply the tracking to a solid (from which I will later export data to Flash) it aplies not only Corner Pin keyframes, but also Position keyframes. This doesn't work for me, I need the solid's position itself to be static, the illusion of movement and distortion only being "created" by the Corner pin effect itself.

Any way to achieve that?

Many thanks-
Wilhelm

If you track with Mocha then you can export only Corner Pin data.

thanks. I'm a bit hesitant to involve Mocha since I want to have a simple workflow (sometimes tracking has to be done in comps within comps etc) but if I find no other way I'll try it.

I believe you will find Mocha to be very easy to work with in any workflow - just track the clip you need, export data and paste to your layer in AE.

Problem with Mocha, if i understand correctly, is that you have to use it with already rendered files. I want to track items in precomps. Any solutions not involving Mocha?

thanks -
Wilhelm
