Tracking a building model in driveby footage
I have a client who is asking me to track a 3d building model (3ds) into driveby footage of the future site. I have after effects cs4 and mocha v2. Is there any way to have the building integrated into the moving footage and locked in place?
My other option is to use a sketch up rendering of the building as if a car is driving by it, the problem with this is that the speed of the sketch up render and footage don’t match and Im having a rough time matching these up.
My ideal would be to put a 3d model in, lock it in place, and have it change scale and perspective as the footage drives closer.
Any thoughts?

One other way to do it if you can track the camera data from your clip like Dave suggested with Syntheyes, Camera Tracker or Boujou (Voodoo can do that as well and it’s free). Then if the building permits ( if it’s a building that can be simulated with flat surfaces, cubic building blocks) you can actually build a 3d model in AE using 2d textured planes. You can actually get pretty complex with that – if you have time check my demo reel (5.1) here on the Cow. Somewhere in the middle there are a few buildings (4) morphing from one shot to another. 2 are done in with a 3d package and 2 in AE entirely and most people did not think that possible.

Thanks for the information. So I would need a program like syntheses- would pixel farm pfhoe tracking software work as well? Unfortunately I don’t have access to c4d so I’d be looking for another solution this time around. If I tracked the footage in one of the tracking programs would it be possible to attach the model to that movement in ae?
I would be willing to purchase inexpensive tracking software, so any solution that would involve that and AE would be wonderful, if possible.
Thanks again!

footage could be solved by the foundry’s 3d tracker then use zaxwerks 3d invigorator all without leaving AE!

Does anyone have a tutorial on how one would ideally execute this? I would like to know what programs would be involved and the workflow that would be needed to create this. Thanks to everyone who has responded and given input.
