Help with Mocha - Plane not tracking properly!

Hi everyone,

I've doing VFX for a short film, and the big VFX shot involves a billboard replacement with some camera movement.

I have the footage and the graphic that will be put in place, but I'm running into some issues when trying to track the camera movement in Mocha.

The camera is on a dolly, so it tracks the sign, but also pans on the tripod, essentially orbiting the billboard as it passes it. The edge also goes off screen for a brief moment. The track seems to work fine (backwards and forwards) until the movement.

It can't quite seem to follow the plane as the camera pans around. I've got position, rotation, scale, perspective, and shearing all checked.

Is there something I'm missing?

It would have been an easy track if it was shot a little better and you had put some detail on the temporary sign. It is a lack of detail in the temporary sign it causes the grass to foul up the track.

We honestly can't know. All you have done is write a longwinded, but vague post with no real info in it. Show us the footage, provide screenshots, explain the relevant settings.

If you have already gone through the tutorials on using Mocha for Corner Pin or have successfully use Mocha to do corner pin work before, try this:

If you are new to Mocha go over to the company website and run through some of the tutorials. It's not completely intuitive and your AE needs to be up to date. You don't need to be on the latest version, but your version must be up to date. There were some bugs that have been fixed.
