Single camera production involves using a single mobile camera to film various shots and angles of a scene. This technique was pioneered in early cinema and remains the standard for filmmaking today. In contrast, multi-camera productions use multiple fixed cameras simultaneously and are usually used for genres like sitcoms which require capturing many actors and locations. Single camera allows for more directorial control and flexibility in locations but takes more time due to needing multiple takes from different angles. It remains a popular technique for films, dramas, and music videos due to its ability to immerse viewers in a story from the perspective of characters.
