During the shoot, your job goes beyond pressing record. First and foremost, you need to be a coach. Balance critical feedback with support and be quick to give encouragement after each take. This is why conducting a table read during the scripting process is so important: It's easier to give feedback when there's not a camera in the room. Remember, be a little silly during the shoot or your talent will be on edge and uncomfortable — and it will show in the footage.
Tone: Are you serious or sarcastic? A great approach to define your tone is to use the "We are ____, but we are not ____" exercise. In this framework, develop three bullets to help you understand the tone of the video content you're going to produce. For example, "We are humorous, but we are not over-the-top." These tone bullets are meant to guide you toward consistency.
When it comes time to shoot, clear out unnecessary people from the room and turn off the overhead lights. With your three-point lighting setup, there will be no need for those harsh fluorescents. When — and only when — everything is set up, call in your talent. There's nothing worse than being nervous, and then having to anxiously watch as lights are turned on and the camera is tested.
