A crucial factor in creating an air of professionalism in a video is the sound. In this sense, audio is truly king. Capturing good audio to accompany your video is essen- tial. Good sound is, in most cases, transparent. If you’re able to record your tal- ent’s voice clearly and cleanly, the audience won’t notice, which is exactly the reaction you’re looking for here. If you record echo-laden bad audio, the audience will notice, and not in a good way.
