3D PiP keyer introduces 2-pixel wide background distortion outside its key area.
The distortion is best viewed when the edge of a transparent key area moves over high contrast background at an angle other then 0, 90, 180 or 270 degrees. It is also visible with a solid video, but it is not as destructive as a moving transparent edge.
Project to reproduce the distortion: 3DPiPDistortion.zip (http://zabcia.ca/pics/3DPiPDistortion.zip)
Sequence 1 is a spinning graphic, with arrows pointing at the edge of the 3D PiP. When played in a loop, one can see the distortion just beyond the arrows. Notice that the distortion is impossible to see over the solid color.
In the second sequence, a similar test is performed, except instead of spinning - zoom is used. Notice that the graphic is at a small angle, otherwise it would be impossible to see the distortion.
And finally the third sequence demonstrates the distortion when the 3D PiP key is a solid (hard to see, just a small (1 or 2 pixel wide) bend in the background lines).
