Reply to comment by EC-Texas in TIL, in film, a clapperboard’s purpose is ensuring proper synchronization of audio and video in post-production. It provides a distinct “clap” along with a visual event for the editor to reference at the start of a scene. by PianoCharged

Oh my yes. Although these days a tentacle sync is used to keep the camera and sound in sync automatically. Otherwise automatic sync is a common tool in editing software to match the scratch audio (the cameras own mic sound - usually very low quality) to the proper audio recording.
