Is there anything in the movie that can collect sound? Is this for Mike? What else is used for recording?

If only DV short films are used, it is recommended to use Bouhmik, which can reduce the noise. Hold the BooMIC in the shooting range high, connect the mic cable to the photographer's machine, and put on the headset to let the photographer listen to the live broadcast effect. If there is noise, you can schedule or remake it immediately, without waiting for the trouble of later repair. Later, if you want to add some scene sounds to the scene, you can record them, such as some birdsong and running water, and then add them as background live sounds during editing to make the picture feel richer. Of course, if the field synchronous radio reception (picture and sound synchronous recording) is not ideal, you can also record sound and replace the unsatisfactory sound at a later stage.
