Clapper Board and Slate - Organize your footage

The slate (sometimes called a clapperboard) gives you a visual reference for each shot. You speak the scene and shot number for audio reference. Finally the clap gives you a single frame at which you can sync the sound to the video. Be sure the clap is clean and crisp. Sometimes it's necessary to slate a shot twice, in that case you say, "Second sticks," to prevent the editor from syncing to the wrong spot. Every time you move the camera in a scene that's a new shot. It's conventional to add a letter (stating with A) to the shot number and call it by a name that starts with the letter. For example, "Scene 12 apple take 4," means this shot goes with scene 12, it's the second camera move and it's the 4th attempt on filming this same shot.
