I am looking for a way to export a 2D track into a 3D package. What I would like, is to have a static (non-moving) camera and an animated locator (or null), that matches the exact motion of the 2D track when looking through the camera in the 3D package. I also require that the locator does not have animation in the z-axis (movement that towards and away from the camera).
When I export a camera track from a matchmoving software (Boujou or 3dEqualizer) the camera is animated with static locators, so this is not what I want.
When I export an object track from a matchmoving software, the locators are animated and the camera is static, so this is what I want. However, the locators are animated in z depth (ie. they move closer and further from the camera), and they do not exactly match the 2D track that they were derived from in the matchmoving software.
The only thing I can think to do, is to 2d track the nose in comp, then attach a tracking marker to the track and render out a new plate. I would then open that in my 3D package and manually move the locator over the tracking marker while looking through the camera, frame by frame.
