In class, we learned about the uses of clapper boards and how they are vital part of the production. Clapper boards help the editors know what clip they are editing and helps them sync the audio from an external microphone. Using a separate microphone will mean you will get an audio file and a video file and in order to match the audio to the video a clapper board is used. When there is an external microphone that’s not connected to the camera you will need to sync the audio with the video. Clapper boards are used for this procedure. A clapper board is brought into frame before the director calls action. The person holding the clapper board then calls out the relevant information on the front of the board and closes the clapper board. Later in post production, it gives a visual and audio point to sync external microphones with. The editor then goes frame by frame and finds the exact frame that the clapper makes contact with the board. Then they listen out for the sound of the clapper board on the separate audio track. Using the audio levels the editor matches up the video to the audio from the external microphone. If a clapper board is not used with an external microphone it makes the editors job a lot more difficult and it means they might not be able to perfectly sync the audio and the video properly.

Using a clapper board can also tell the editor important information. It can tell the editor the order of the shots. Other helpful information can be displayed on a clapper board like the cameraman, so if there was a problem with the shot they would know who to talk to. The person holding the clapper board shouts out useful information before clapping the clapper like the scene and the take. This helps the editor know which files match up with which audio clips.

In class we learned how to sync audio to the video. We used a clapper board to demonstrate the different types of shot and how to sync them. We used an external microphone and a camera to record it.

Scene 1 Take 1 is known as a head slate as it is used at the beginning of a production.

If you want to change camera angles half way through a scene you add a letter to the scene. For example, 1A, 1B, 1C but when you get to the letter “I” then you skip it as it looks very similar to a “1”. You skip “O” as well as it can look like a “0”. After you have got through all 24 letters you then go on to double up letters for example 1AA, 1AB, 1AC.

If there is no sound that needs to be synced then you put MOS in the sound box. This tells the editor that an external microphone was not used and that there is no need to sync and audio. MOS can stand for “mit out sound”, “motor only sync” or “motor only shot” depending on who you ask. There is no need to shut the clapper as there is no syncing required so to make it more clear to the editor the person holding the clapper board puts their hand between the clapper and the board.


A tail slate is the last scene of a production and is shown by holding the clapper board upside down.

We experimented with lighting in class creating different effects.
