Slo-Mo video capture is what all of the cool kids are doing these days, and if you happen to own a shiny new iPhone 5s, you can now join the fun.
The slow motion effect is the result of video that's captured at a very high frame rate, and then slowed down. This allows you to have video with reduced speed without any herky-jerkyness. The end result is a professional quality slow motion effect that you and your friends will love.
