Here’s a quick way to know if your camp video is working as hard it can for you: Try watching your video with the sound off. Ask others do to the same. If you (or they) are still half-way engaged, you know your video is a winner.
Like pictures, video is a visual marketing medium, and people often make yes or no decisions about signing up for camp based on the pictures you show. Adding music or sound later is only a bonus.
One great and fast way of making a video is to use Animoto. You can simply type in your titles, upload your pictures, pick for a music file, and push the button. A minute or so later you have a great profession video with your camp pictures already to go.
