What does a clapper board do?
Similarly one may ask, how does a digital slate work?
Once the tape recorder and camera are rolling, the clapperboard operator places the clapperboard in front of the camera so the camera can see it, reads the scene and take information so the tape recorder can hear it, and then claps the clapper. The digital slate is the more modern form of the clapperboard.
In this manner, are clapper boards still used?
Closed 3 years ago. Clapperboard (or slate) is used in movie primarily for two purposes: To assist in synchronizing picture and sound (with the help of a clap). It makes the editor's life easy.
Called a clapperboard or a slate board, among other things, it's used to make syncing audio and film easier and to identify takes and scenes. The two are synced, and the board just has to be shown to the camera before a scene for the editors to find the same point in the film and audio tracks, no clap needed.
