Kevin Reiner3D precomp question. What?

Hey all,

Trying to brainstorm the best way to do the following.

I have a grid of video squares (all the rage these days). The squares are precomps containing a 3D environment of living rooms with people doing typical things. All stills set up at varying degrees of Z-depth to show perspective change when the camera moves.

I want the camera to fly into one of these squares, but without a change in perspective until the camera almost fills the screen with the video square. At a certain point I want it to start paying attention to perspective, but not until we get really close. Hope I am explaining this well enough.

It is kind of similar to the Carnivale opening:






I am guessing that I need to cut between a collapsed and an uncollapsed version of my precomp? Maybe? Any suggestions would be much appreciated.

Thanks,
Kevin

If what you're trying to do is just like in the example you posted, then treat your moves as separate comps and match the in and out frames.
One comp for the camera moves outside the pictures, all the way to when you get close enough that one image fills the frame- then you have a second comp with the image decomposed in 3D space, and a new camera move in the images space, and so on.
From my experience that's the easiest way to manage the moves and details. At the end you can render the segments and bring them in rendered in a final editing comp (or edit them in FCP or Premiere), or bring in all the comps in a master comp and render all out.

Thanks Ted,

I did almost exactly as you described and it came out well.

I've attached an initial test.
