I have been trying to track this Shot

The signs on the left in this shot.
At first it’s easy but the motion blurred sign posts pass the signs and als the drivers head obscures the signs.
I have used the dash, mirror, driver and posts as other layers.
The shot:

When we the shot was actually tracked we used a 3D tracker and shake.
But am trying to do this in mocha instead.

Tips and ideas?

Hi Gary,
You can use multiple shapes to subtract the foreground elements as well as animate the search area… Stop the tracker and move the search layer on the sign as the face obscures it. I do think that in this case, the last frame will probably need to be hand tracked.

Best,
Ross

Have read the manual and did the tutorials.
The tutorial with the posters makes it look much easier…

Tips and ideas?
