Video is a rich medium. As the old saying goes, "An image is worth 1,000 words." The impact of video is arguably worth 10,000 words because it is so rich. It lets you convey words and images, but it also lets you convey emotion. If there's a voice-over, or if your face is on a video, you're able to convey so much about how you feel-the energy that you are bringing to the table when you're focusing on a certain business challenge.
