A
clapperboard is a device of hinged boards that are struck
together before filming to synchronize the starting of picture
and sound machinery.
The
production information to be written to the upper part of
clapperboard includes
-
the name of the film
-
the numbers of the scene and the shot
-
possible production numbers or codes
The
clapperboard makes it possible to synchronize the sound and
film material during editing.
Usually
the clapperboard is used in the beginning of the take, but
it is also possible to use it in the end; then it is used
upside down.
