What should I do if the video taken by my mobile phone is noisy?

First of all, there are probably several reasons why mobile phones will produce noise when shooting videos:

1, the microphone of the mobile phone is not a professional recording device, and the radio reception effect is relatively general. The biggest purpose of the microphone on the mobile phone is to ensure the clear voice of the call, regardless of the recording problem of taking too many videos.

2. The microphone of the mobile phone is omni-directional, it has no directional characteristics, it contains all-directional sounds, and all directions of sounds, including noise, will be included.

3. There is no guarantee of quiet shooting environment and no special recording environment in the daily shooting process. Shooting in a noisy situation is easy to make the background noise too large.

4. The mobile phone has no noise reduction device in sound, and there is no very easy-to-use software to process sound, which leads to low controllability of recording.

Solution:

1. Use an external microphone.

Combined with the scene of shooting video, you can choose an external microphone to pick up the sound, such as a wired microphone or a wireless microphone. External microphone is more suitable for long-distance pickup than mobile phone, which can maximize the sound quality.

When choosing an external microphone, you should choose a directional microphone. When shooting video, adjust this microphone to your own direction, and the voice recording will be clearer, while shielding useless noise in other directions.

2. Eliminate noise by software later.

Friends who are self-media should have a lot of video editing software, which basically has a function, that is, sound processing. You can reduce the noise of sound by adjusting the sound channel, but you can't completely eliminate the noise. After processing, the noise of the video is much lower than that of the original film.

3. Re-record the audio.

This is probably what many friends are keen on. Take a video with your mobile phone first, regardless of the audio. In the later video clip, the original sound in the video is directly eliminated and new audio is re-recorded. It's like film making, recording sound with professional recording equipment and then blending it into video. This is the perfect solution.
