Description

A sound-light integration slate for radio and television program production

technical field

The invention relates to the technical field of radio and television program production, in particular to an acousto-optic integration slate for radio and television program production.

Background technique

The scene board is written with information such as the number of scenes, the number of shots, the director, the title of the film and the film company. One end can be opened and closed, and a crisp sound can be recorded. It can be used as the opening mark of each piece of film, which is convenient for identification during editing. Using the sound of the board to accurately locate the sound image is the starting point of post-effect editing, which greatly facilitates the production of radio and TV programs. However, in actual use, we found that the existing board still has some shortcomings. ,for example:

1. When recording a radio and television program, the entire crew must perform according to the percussion sound of the slate, but sometimes the recording environment is noisy, and many actors cannot hear the sound of the slate, resulting in the performance rhythm. , disrupting the filming of TV programs;

2. Photographers and lighting engineers also record according to the sound of the slate. During post-production, editors often fail to capture the moment when the clapper is closed, and the audio and video cannot be synchronized. It needs to be proofread multiple times, which will bring benefits to the post-production work. A lot of trouble came.

Based on this, we propose an acousto-optic slate for radio and television program production, hoping to solve the existing technical problems.
