Editing Clapperboard (section)

==Description==
The clapperboard combines a [[chalkboard]] [[slate]] or acrylic board with a set of clapper sticks across the top; one stick is fixed to the upper edge of the slate, while the other is attached to it by a hinge at one end. The slate displays the name of the production, the scene and "take" about to be performed, and similar information;<ref>{{cite web |last1=Soniak |first1=Matt |title=Why Do They Click That Board Thing Before Filming A Movie Scene? |date=4 December 2012 |url=http://mentalfloss.com/article/31781/why-do-they-click-board-thing-filming-movie-scene |publisher=Mental Floss |access-date= 2015-12-27}}{{better source needed |date=October 2017}}</ref> a camera assistant holds the clapperboard so the slate is in view of the cameras with the clapper sticks already open, speaks out information for the benefit of the audio recording, then snaps the sticks shut.<ref name="Tomaric_Page_298">{{cite book |last1=Tomaric |first1=Jason J. |title=The Power Filmmaking Kit: Make Your Professional Movie on a Next-to-Nothing Budget |date=2008 |publisher=Focal Press |location=Burlington, Massachusetts |isbn=9781136060229 |page=298 |url=https://books.google.com/books?id=tNnzF21lBf4C&pg=PA298 |access-date=3 February 2022}}</ref>

The shutting of the clapper sticks is easily identified on the visual track, and the sharp "clap" noise is easily identified on the separate audio track. The two tracks can later be precisely synchronized by matching the sound and movement. Since each take is expressly identified on both the visual and audio tracks, segments of film are easily matched with corresponding segments of audio.<ref name="Tomaric_Page_298" />
