A board which contains the scene name, number, and film. A person ‘claps’ the board shut at the top while saying “Action” or “Cut” to indicate the start and stop of a scene that is being filmed.
This is used to synchronise the audio of the clap with the visuals.
Clapper Board was approved as part of Unicode 6.0 in 2010 and added to Emoji 1.0 in 2015.
