Having the 3D on top left us with two problems. One, we wanted the edges of the model to blend into the cheek and forehead. Feathering the matte of the video allowed us to do this easily. Two, this go in front of the faces like arms, butts, etc. This allowed us to deal with this in after effects solely. Always nice to have get rid of any extra work when on a deadline.
The video didnt need to have too many keyframes since we put the videos on a timeline. This allowed us to keep in sync if anything were to hang up. The downside to this is you have to fully load the video before you can play it back. Also because we used mattes in the video instead of putting the model on top, we had to use FLVs instead of F4Vs and there was a size to quality concern. Some of the videos were pretty big. The one with Vanilla Ice in Las Vegas was about 15mb i think. That one was by far the longest. The vectors of the bitmaps for every scene are kept until they you leave the room view. All the bitmap data is disposed of then. We have the cropping data for each frame so that allowed us to only take the bitmapData we needed and save memory. I think with all 4 faces uploaded for the longest city (nyc) it was roughly a 300 mb gain (541 frames of bitmaps). Thank you for everyones comments.
