Video is a visual medium.
There are successful videos that include only a person talking in front of the camera. However, most videos work better when they leverage the power of visual storytelling.
The key word here is story.
Yes, now everyone has the technology to run out and film and take photos with their cameras or inexpensive DSLRs. But if the photos don’t create an emotional connection with the viewer or don’t give your audience a taste of the event or place or person, even the most expensive camera set up wouldn’t have saved you the heartache of feeling like you’ve missed a major opportunity to share your story.
