How did you get the sound when filming?

There are three kinds of radio stations when making movies and TV plays.

1, synchronous recording.

In this recording mode, if the camera does not turn on its own recording function, it will not record itself, but use professional recording equipment to connect the camera and record at the same time, and the audio will be recorded into the recording equipment. Then, according to the camera time code, compare the recorded audio tracks and make post-production to eliminate noise. The finished product is obtained after mixing.

2. Post-recording

The recording microphone is directly connected to the camera without additional recording equipment.

At the same time, one person records, commonly known as lifting the pole, that is, lifting the microphone, and the other person hangs a small recording station, that is, recording equipment. Less professional equipment, generally used to shoot small budget short films or internal MVS.

Synchronous recording equipment can record clearly and directionally, reducing the incoming of surrounding noise. Of course, it is impossible to have no noise at all. But the recording equipment is professional, which can distinguish noisy sound from directional sound source, and can clean up the noise later.

There are few films with the same sound in China (that is, live recording), and the recording is very quiet. Some Hong Kong directors have re-recorded the scene of the same sound many times, and sometimes they will record the sound separately after the performance. Although China also used the original sound, he still made it in the recording studio, and the actors did it again, so the sound of every TV series was so clear.

3. Pre-recorded

Some must record the sound in advance, and then play it out when shooting the picture, so that the actors can listen to the rhythm of the sound, such as the arrangement of Chinese Peking Opera and traditional Chinese opera. This is called pre-recording.

Development status:

With the continuous development of digital audio production technology and the wide application of surround sound system, the audience put forward higher requirements for audio-visual language in film and television works. Film and television works should not only satisfy the audience's visual experience, but also take care of the audience's auditory experience. American film and television art pays more and more attention to dubbing in the later stage of works, with the aim of pursuing the dynamic and fidelity effect of sound.

Traditionally, film and television works belong to the art of regret. In many cases, in order to maintain a good picture effect, it is necessary to give up some recorded synchronous sounds and highlight the details of the sounds through later dubbing to make them more expressive.

Therefore, synchronous recording of movies and TV has become a development trend. Because domestic film and television production is often limited by funds, in order to make up for some defects in the early stage of recording, we should pay more attention to the pruning and re-creation of actual sound in the post-production.
