I'm relatively new to after effects and I'm working at integrating some elements into video footage. I'm trying to use the 3d camera tracker to map out the video, which has already been edited with a large number of cuts. Is there a way to set the tracker to analyze only the frames within the work area? Despite my work area being set on only around 60 frames, the entire 1170 frames continue to get analyzed...and fail because of the numerous scene and camera changes. I'm using a mac with cs6 is that helps. Thanks for your help!
I would export the clip for the camera tracker separately in a lossless codec and use it in AE to do the camera track.
As Dave said, simply export the clip you want to be tracked separately. Since it will produce a normal 3D camera layer that can be copied&pasted and mocved around, it would be easy enough to transfer the data to your main comp/ timeline later...
The camera tracker works on the in and out point of a layer not the work area or the in and out point of a composition. Here's what I do. Split the layer where the shot starts and ends and only track that part. I do this all the time.
