At this point, the consumer is weighing their options and deciding on the purchase. Therefore, the goal of this kind of video is to make your audience visualize themselves using your product or service — and thriving. There's a reason 4X as many customers would rather watch a video about a product than read about it. Videos are able to display functionality and leverage emotions in ways a product description never could.
Here's where the final lesson of composition comes in: continuity. Continuity is the process of combining shots into a sequence so that they appear to have happened at the same time and place. A key part of continuity is making sure any ancillary objects in the scene — for example, a cup of water on a desk — stay in the same place (and have the same amount of water) throughout all of the shots.
Find a location. Decide on a spot to record. If you can't go to a professional studio, try to pick a quiet room away from distracting external sounds like sirens, opening and closing doors, and people talking on the phone. Read your script aloud, and pay attention to the room's acoustics. Does your voice echo or sound muffled? If so, consider recording in a different space or adding furniture to fill in the room.
Professional cameras, like DSLRs, give you fine control over the manual settings of shooting video and allow you to achieve the shallow depth of field (background out of focus) that people rave about. While they're primarily used for photography, DSLRs are incredibly small, work great in low light situations, and pair with a wide range of lenses — making them perfect for video. However, DSLRs do require some training (and additional purchases) of lenses.
