Tracking Problem
on Mar 30, 2015 at 3:53:13 pm

MOO everyone,
I am trying to track a smartphone screen, and replace it. I am using the perspective corner pin, and tracking the four corners.
My problem is, in one shot, one of the corners goes off screen for a bit. I could track that corner manually for these 15 or so frames, but it seems to be impossible to move the bounding box off the screen.
Is there a trick I'm missing?
Thx in advance
Simon

Use Mocha for this task instead. Being a planar tracker, it doesn't freak out if a part of the plane goes off screen.

Thanks for the reply Dave.
It's as I thought. Now I have to do a tutorial or two :-)

I would recommend starting with these tutorials:
http://www.imagineersystems.com/video/?tagFilter=mocha%20Fundamentals&&dd=d...

  • If the screen does not have many reflections, it can be as simple as drawing a shape around the entire screen.
  • Track.
  • Display the "surface" the blue rectangle that represents your track data and adjust it to where you want your insert.
  • Copy AE corner pin data to clipboard.
  • In AE paste the data to your insert layer.
