How do you add a dramatic flair to your mundane video clips? You play it in slow motion, that's how. And now that YouTube has introduced a built-in slow-mo feature, you don't even need to capture footage using a high-speed camera. Just click Edit, navigate to Enhancements and hit the icon emblazoned with a turtle to make footage crawl at 12.5, 25 or 50 percent of its original pace. Note that resulting clips can last no longer than 10 minutes, and the feature might not be available in some countries outside the US just yet. Head past the break to compare two samples and see how the new feature can transform your YouTube vids, Dave Chappelle-style.
