Using a Roto-d Auto-Track
This is a more hard-core approach. Since doing the roto step is time-consuming (even though the roto can be very rough), we recommend it mainly in situations where the roto is very simple, where the 360 VR camera was rigidly mounted on a vehicle or the camera has a blind spot, and therefore the mask doesn't move.
- Run the 3D Tracking Wrapup script to convert back to the full 360 VR view, including updating the trackers.
- Go to the Roto panel, set up animated roto mask(s) to mark as Garbage any camera platform visible in the imagery, the sky, and any other unproductive areas, so that no trackers are generated in the next step. (It's easiest to do this on un-stabilized footage, as described, which is why the Wrapup script is used instead of the Stabilize from Camera Path.)
- On the Features panel, Clear all blips and Blips all frames, then Peel All. This will give you many more tracked 3D features throughout the scene, not just in the area of the original linear track.
- Enter " make all unsolved trackers zwt" into Synthia, to obtain 3D positions for all the tracked features.
- Use the Sort by error option and the hierarchy or graph editors to identify and delete any problematic ZWTs.
- Run the Stabilize from Camera Path script.
