Rotoscoping means (in video production) editing frames of live action
on a frame by frame basis to add animation.
An example: Take 15 seconds of live action of Peggy Fleming skating.
Use a frame grabber to get each frame from analog to digital.
Break out the old Quantel paintbox and add a few sparkles around Peggy's skates.
Write the frame out to back out to tape (convert from digital back to analog)
repeat (15sec*30fps = 450 frames).

It expensive (@ $40/hr for Quantel operator) and it can look very bad. 
It can also look very good.
