Here is basically what I am trying: I have a solid rectangular object in the real world which is being rotated relative to the camrea.
The object starts with the plane of interest being parallel to the viewer. I then crop the a secondary video to match refrence points on the object leaving a border.
Now I rotate the object so I need to rotate the secondary video track to keep the video "On" the object. The problem is that the 3D track appears to have a different virtual lens than I use in shooting, so the object and the video do not maintain the perspective relation as the rotate. The front edge can be made to match the video, but then the rear edge of the 3D track is shorter than the real video rear edge.
If someone knows the lens equivalent, I can shoot it without tons of trial and error. Or better yet knows how to change it in Vegas, I can't find a setting.
Hope you can understand what I am talking about here.
