Louis has been doing a medical show on YouTube for about ten years. The show, Geeky Medics, highlights medical issues for caregivers including bedside manner. But he's having issues where the mic is picking him up behind the camera. What kind of boom arm should he get? Leo says that there are a lot of really good ones out there. Leo recommends watching Alex Lindsay's Office Hours Video Podcast.
Leo also recommends getting a spider mount, which will act as a shock mount for your microphone, limiting vibrations translating to the microphone itself.
