Could be.  My guess was that "clap" was something related to animation work.
As I recall, in conventional filmmaking the "clapper" is the little hinged-
board gadget that gets banged together at the start of each scene; its role
is to provide a timing mark to synchronize sound and image, plus putting
things like the scene number on the image.  (I'm not sure how much it's
used now, since I think many movies now have the sound done later, rather
than at the time the image is being shot.)  This sort of bookkeeping is a
serious issue for animation groups as well, since a non-trivial animation
project requires keeping huge volumes of data organized.
