Slow-motion video is normally recorded at the highest frame rate possible, and many cameras offer rates as high as 1540fps. By putting this video onto a timeline set to playback at a lower fps rate – such as 20fps – the one-second video will now take two seconds to play. For example, capturing a video at 60fps (frames per second) means when you watch the video, you’ll observe 60 frames per one second of the video. In order to achieve this, you must capture frames at a higher rate than the intended display speed. With slow-motion video, moving images are displayed at a rate that appears slower than in real-time. In order to understand what it is and how to slow-motion a video, you need to know about frame rate (fps), which is the number of still images making up one second of the video. You might use a slow-motion video to emphasize a specific scene or slow down an action you wouldn’t normally see in detail, like a flower opening its petals or a balloon bursting. Slow-motion video is one of the coolest video effects where time appears to slow down.
