Using unprofessional microphones?

If that's the case, why not just use a mobile camera to shoot and record movies? But if every microphone works, why do some microphones cost tens of thousands of yuan while others only cost one hundred or eighty yuan? It's not surprising that a recording studio has various types of microphones.

To record high-quality live recordings, the correct type of microphone must be selected. Strong directional microphones are suitable for exterior scenes, directional microphones are suitable for interior scenes, and for smaller interior scenes, non directional microphones can be used. The stronger the directionality of the microphone, the stronger its ability to selectively receive sound from the front *, and the higher the signal-to-noise ratio.

Underestimating the impact of location?

When you check the location, the professional approach is to bring the tuner along because he knows how to record the best sound effect. A room without windows or furniture can easily generate echoes, making it difficult to record or edit sound. Remember: It's difficult to eliminate echoes during sound recording, but it's easy to add them.

Recording music or background noise simultaneously?

If the shot passes through but there is noise mixed in, how ridiculous! Once the background sound is entered in the dialogue, it is impossible to eliminate it. But if you only have dialogue, you can easily add background music and necessary noise. The less noise in your dialogue, the better for post production.
