Yes, camera shooting is mainly about body movements. In fact, sound is secondary, such as a wedding, which is equivalent to a documentary. As long as you have a camera, there is sound. If it is a professional camera, such as a movie, the sound is recorded later. So none of this is wrong. But there is one problem that needs attention, and that is communication with others. For example, if you take a wedding, you should discuss with others what the procedure is in advance, so that you can make preparations in advance. To some extent, if your voice has some defects (there is no other meaning here, just saying), then you may shoot better than others in image, and you will pay more attention to your picture!
