  corner pin relative to comp, not the pinned layer

  Posted by Scott Geersen on May 9, 2007 at 5:51 am

  hey guys,
  something that’s confusing me a bit: i have to track some photos onto a wall the hard way (manually) and i thought i could just track nulls to the corners and then link a corner pin via expressions to the position of the nulls. not so. i forgot that the corner pin is relative to the layer being pinned, not the comp…

  is there a way to force the corners of my layer to map to the position of the four nulls i have?

  i can’t really use any kind of tracking program like boujou in this case because the sequence being tracked is a 3d shot with forced fake perspective, which confuses the heck out of tracking programs. and we have no access to the original 3d sequence, hence the manual position of nulls.

  i didn’t use four point tracking because the objects go in and out of screen, and it’s easier to animate the nulls by hand than muck around with half-track-data-half-manual-data.

  acutally: i just thought of one silly way, and it’s not ideal. if i precomp all my photos to the size of my main comp, everything will work… BUT i’m worried about quality loss. i’d prefer to bring in oversize images and be able to force corners to null positions. any ideas, people?

  thanks,
  scott.
