If you just picked up your iPhone 5s, you may be itching to record some slow-motion video. (I know I was.) But due to the way Apple's slow-motion feature is implemented, sharing your brilliance with the world may take a few extra steps.
How slo-mo works
Despite what you may think, Apple's slo-mo mode doesn't record in slow motion at all. Instead, it records in real-time, capturing more frames of motion than your eye can perceive.
Your average online video is displayed at 30 frames a second. The iPhone 5s camera takes four times that number, capturing 120fps (frames per second); as a result, 1/4th of a second has the same amount of frames that a regular second of video would have.
The iPhone 5s has special software in the Photos app to slow down parts of your clips.
Played at its normal speed, 120 frames a second is awesome for filming things like sports, as you can see moves and plays more clearly. But Apple has also built software into the Camera and Photos apps that let you automatically slow down a portion of your 120fps video so that it displays at the 30fps we're used to.
