Whether you make videos for your own enjoyment or share them on sites like Facebook and YouTube, what happens if you want to make your video in slow-motion? In this article, we’ll explain what slow-motion video is and how to shoot slow-motion video on your smartphone – then we’ll take you through some of the best slow-motion video editors and apps around. We’ll even answer your most frequently asked questions about the topic, so keep reading.

What is Slow-Motion Video?

Slow-motion video is one of the coolest video effects where time appears to slow down. 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.

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. With slow-motion video, moving images are displayed at a rate that appears slower than in real-time. In order to achieve this, you must capture frames at a higher rate than the intended display speed. 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. 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.

Slow-motion video is normally recorded at the highest frame rate possible, and many cameras offer rates as high as 1540fps. It’s possible to shoot slow-motion videos on your smartphone, though and 60fps, 120fps, and 240fps are more common.

How to Shoot Slow Motion on Your Smartphone

As we mentioned above, you can shoot slow-motion videos on your smartphone, whether your device runs Android or iOS. Most flagship smartphones incorporate the ability to record slow-motion videos into the camera. If you don’t own a flagship phone and are wondering how to make your video slow-motion, there are slow-motion video editors and apps that can help you slow down a video.

If you’re wondering how to shoot slow-motion videos on your phone, here are some tips and tricks to help:

  • On flagship Android phones like the Samsung Galaxy S20, S20+, S20 Ultra, or the new S21 range, there’s a feature called Super Slow-mo, which shoots action at 960fps. When played back at 30fps, it’s 32x slower, creating great slow-motion videos. Just open the camera app, tap Super Slow-mo, and start recording.
  • The iPhone 11 or 12 records videos as normal in Slow-mo mode, but you’ll see the Slow Motion effects on playback. You can also edit your video to start and stop the Slow-Mo effect when you choose. Just open the camera app, choose the Slow-mo mode, and start recording.
  • For the best results, your shutter speed should be double that of your frame rate (e.g., 1/125 when shooting 60fps). Most smartphone cameras have Pro settings where you can adjust the shutter speed.
  • Bear in mind that a higher shutter speed and frame rate calls for more light. If you’re shooting a slow-motion video indoors or in poor light conditions, you might need to add studio lighting for the best results.

If in doubt, why not try out one of the best slow-motion video editors and apps below? Many will do the hard work for you and are designed for beginners with little to no experience.
