This "playing around" isn't wasted time — it's all about learning how to get the most from your resources. As a bonus, it usually produces something that's fun to watch, too!
Consider this "videoscrapbook page" from Wichita State University video/editing guy Rik Dubiel, who incorporates footage from a Cannon HV20, some fun music, nicely choreographed color effects, and one cute as a bug little boy exploring his back yard.

Did you catch the basset hound wagging his tail to the beat? Nice work, Rik!
