One of the stand-out features of the iPhone 5s was the 120fps slow-motion video, and the iPhone 6/Plus took this even further, allowing silky-smooth 240fps video at 720p. Sharing that video, however, isn’t always easy: many online services don’t recognize that the video is slo-mo, and play it instead at full speed.
