Question What is the proper technique for tracking a shot like this?

Sry, would post the vid but i gotta go to work. Slow connection.




I'm basically walking down the bridge towards the skyline, the camera has some wobble.

Overall, I want to add more buildings into the skyline. What is the best way to track this scene?

I'm using After Effects CC with Cineware.

AE camera tracker is automated,one button process AFAIK,
there is not much you can change.
Hopefuly after tracking you will be able to place two steady
solids, one to roto the existing buildings and one to draw the new
ones behind.What else can one say?

Mask out anything that moves(cars, people etc) before you track.
By wooble do you mean rolling shutter?

Both the shakiness and the rolling shutter.

Here's the end result BTW:

I don't know that I'd bother with a 3d track of that footage. I'd use a 2d track and matte painting approach instead.

You can probably get rid of that little bit of vertical shudder by deleting some keyframes on the camera on those frames. It's probably in the either the z- or x-rotation channel, but you'll likely be able to see the spike in the animation curves.
