Your video will need an interface if it is to be instructional/educational (if it is a story/drama, you might be able to bypass this step). That means room on screen for frames, interactive buttons, lower 3rd text or advertisements, and additional motion graphics and still graphics. Plan ahead of time how those graphics will look, and then adjust all camera shots accordingly to accommodate those graphics. We create our graphics in Adobe Photoshop and Adobe Illustrator, and animate them in Adobe After Effects.
