kobuzero ask's: How in bloody-hell did they do this?
Video:
♥ Small Talk = Big Love @ YouTube ( really wish people would not make references to slop-artists' )
At the Photo Works Program:
To show that this is such an old trick, I've pulled-out Paint Shop Pro v3 from 1994.
JASC products were usually w a a a y ahead of their time; [
Photobie can do this in 1/100th the time! ]
Take Two Images and Compare them ?? the results are as follows:

take any image and increase its size by 3% and you have a shadow. [ paint it Black. ]
At the Video Editor:
now simply make Layer 01 transparent on the white colors, except the eyes. [ bottom left ]
now place the 3% larger out-line on layer 2. make it transparent too. [ bottom right ]
?? Lock these two images "as a group" and where-ever one goes, the other will follow.
o.k. ?? now; all your moving backgrounds are on Layer 3 ?? [ time it for 3 seconds. ]
o.k. ?? ?? have your first two layers slide from right-to-left in the same 3 seconds.
Save your 3 seconds to AVI:
your illusion of timing marks 0:46 to 0:49 in
♥ Small Talk = Big Love is now complete.
