3D Trakking to Camera

Hi, all

I have being trying to track live footage to add 3D elements inside After Effects.

I want to emulate this effect:



Right now, I have tried tracking the footage with Mocha (using perspective) and pasting the track data in a 3D Null, then I parented a Camera position, rotation and anchor point to the Null.

I'm having some problems manually tweaking the expressions to achieve the correct movement and position, adding or subtracting values. I'm getting close, but not quite and I wonder if there's a standard way or tutorial to achieve this.

I'm using After Affects CS4 and Trapcode Particular 2.

Thanks for any input

Mocha isn't going to do the job, as you must be painfully aware. You need a tracker built for 3D matchmoving, like Syntheyes. You apply Syntheyes data to an AE camera.

Thank you, Dave

I see Syntheyes it's well documented. I'm downloading the Demo to continue my tests.

Great advice, as always.

The video you linked was 3D tracked using PFhoe: http://www.pfhoe.com/
