Make sure you know what you want your video’s call to action to be. You can include your homepage URL, a “Click Here” button, a thumbnail of another video, social icons, or almost any other form of CTA. These are technically graphic elements, but require a little more thought since you’ll want to consider what your video goals are and how you want the viewer to accomplish them. Think about their user experience and how you can present your CTA in the least disruptive way possible.
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.
