Subject : OT: Object tracking with moving camera
Hello.
I was wondering if anyone know how to object track something in
matchmover, possibly boujou. I have a moving camera with a moving
object.
My first thought was to track the bg with one cam and then have a
fixed cam and track only the obj and export some flying nulls. But i
cannot solve the 3dcamera when i've tracked only the object. I've used
about 10 manual 2d tracks but i get this message.
Cannot locate reference/keyframes necessary for camera solving:
a minimum of 2 images with 7 points in common or 4 points with know 3d
coordinates are required to create reference/key frames.
Tried using automatic tracking and then 3dsolving but got the same message.
If someone could shed some light into this untutorialized matter i
would be happy as larry.
