Syncro-Vox

Syncro-Vox is an extreme form of Limited Animation: A mostly obsolete technique in which footage of the actor's mouth is superimposed upon an otherwise non-moving image. Can look pretty unnatural. Used only for comedic purposes in anything newer than the 1960s.

Just as primitive Rotoscoping has given way to Motion Capture, the great-great-grandson of this technique can be found in the advanced facial performance capture techniques used in Avatar and LA Noire.
