There is a lot more to recording a successful interview than a microphone and camera. You need to make sure you have ample lighting, quality sound, and know how to capture the shots you need. Not only that, but your subject needs some preparation to ensure a Q&A session that can be edited effectively.
Decide where you want to conduct the interview - in an office setting or perhaps on location. Be sure to film some establishing shots as a segue to the interview. Zoom and pan slowly when filming these shots.
Whenever possible, use both the tripod and the lavaliere microphone for interviews. These two things are the best way to make sure your video looks and sounds professional. For "on the street" interviews, they aren't as important, but for seated interviews, they are a must.
FRAMING THE SHOT
COACHING THE INTERVIEW SUBJECT
You want your interview to record and edit easily and professionally. Coach your subject on how you need to conduct the interview so you can get exactly the Q&A you need:
Encourage the subject to make stand-alone sound bites:
"I feel teambuilding was a really important part of my MBA experience" vs. "Teambuilding was really important"
Encourage the subject to restate the question as part of their answer:
"What did you think of the president's speech?" "I thought the president's speech was..."
- Ask the subject to hold position for a second or two before and after answering each question, to give you room to fade in and out in the finished video.
