How to stop the camera and move the world
on Jan 27, 2016 at 2:10:45 am


I have some live footage taken from a moving car looking ahead down the road. I have performed Track Camera in After Effects and have created a 3D Tracker Cam, adding a few solids into the scene. The track looks good.

My issue is this:

I need to create a duplicate composition which is visually identical, but has a stationary camera. The solids within this comp would be the only moving objects.

I believe I can use an expression on a null which inherits the inverse of my original camera's position, and then parent my solids to that, but when I try to handle the orientation issues I begin to get lost.

Does this sound like the right approach for this issue? And is there a straightforward solution that I may have overlooked?

Thanks so much for any ideas.

Maybe I do not understand your issue, but it seems to me that in your duplicate comp you can just use the track data to apply that to a Null (or just use the camera itself), parent the objects you require in the shot to it, then orient them using their individual controls.
