What is a field card?

In fact, the record card is a good way for filmmakers to explore in the long-term practice. They used a small board with black and white stripes, which simply wrote the relevant contents of the film to be filmed. Before shooting each shot, they shot this "board" as the mark of this shot. This step is called "clapping your hands" or "filming" in the jargon of the film industry. In this way, there is a slate shot at the beginning of each film. In post-production, as long as the staff see this mark, they will know which film, scene and shot this film is, which is easy to identify. In addition, clothing, make-up, props and other staff can also use this to avoid flaws in the details of shots taken at different times, thus avoiding mistakes. There are three functions: first, as the opening mark of each film, it is easy to identify when editing; Secondly, the accurate audio-visual positioning is determined by the sound of tapping the board, which is the starting point of later sound effect editing; Third, the basis for staff such as clothing and makeup props to distinguish specific shots to avoid flaws in the details of shots taken at different times, thus avoiding serious injuries to the details.
