i'm fiddling around with the new 3d camera tracker feature in ae/cs6
here's what i'm doing
add 3d cam tracking
assigning the target
right clicking on target and selecting new solid and camera
selecting a logo from the project window clicking select/alt to replace the solid with the logo.
the first time is did it, worked like a charm.
but now, using the same logo,
i get an after effects warning message stating:
3d camera tracker for layer "logo.jpg" require re-analysis because the source dimensions have changed from 1920x1080 to 225x225.
i haven't changed any settings at all.
i created a new comp and started over.
