To make a video of an interview when both parties are in the same location, use a camera on a tripod and a high-quality microphone to capture the full questions and responses of each person. If the interview takes place over the Internet, use a program to record the screens and audio of both parties.
When making a video recording of an interview, make sure that all parties provide the proper consent to appear on camera, as some interviews may cover sensitive information. It is also important to understand the number and location of the interview participants. When the interview takes place in the same location, set up the camera on a tripod to avoid shaky footage, and face it toward the interviewee. Repeatedly moving the camera between people may lead to blurry footage and disrupt the flow of the interview. If you have multiple cameras, you may also set up an additional camera on the interviewer.
It is also helpful to use a quality microphone for recording audio, such as a lavalier microphone, which reduces ambient noise and makes it easier to hear responses. If the interview takes place over a video chat, use a program that captures the computer screen of the person conducting the interview as well. Such programs typically also capture audio through the computer, rather than the speakers, with results in better quality.
