What Is Slow Motion? Tips for Slow-Motion Video

These days, young people are drawn to unusual camera features combined with sound and lighting effects, and slow motion is another fun shooting mode. Slow-motion footage gives viewers a true-to-life feel for every detail. To understand better what slow motion is and how slow-motion video works, let MONA Media find out in the article below.

What is slow motion? Understanding slow-motion shooting

Slow-motion mode is a technique for slowing down video, showing movement in a detailed, artistic way. Instead of recording one second of action as usual, this mode stretches it to up to 10 seconds, producing striking clips. Slow-motion recording is built into most smart devices such as cameras, camcorders and smartphones, and has become one of the most popular creative effects today.

Depending on your purpose, you can use slow-motion mode to make films of different slow speeds and lengths. Using this mode does require attention to its principle, though. Each second of shooting must capture at least 120 frames, but only about 24 frames are played back. That is what makes the footage slow, and the person filming needs to understand this principle to make beautiful, striking moving images.

How slow motion works when TV commercial production

Slow-motion mode works on the principle of recording at a much higher frame rate than the playback rate. The camera records at 120 frames per second or more, then plays back at 24, 30 or 60 frames per second. As a result, the footage plays noticeably slower.

Put simply, if you shoot at 24 frames per second and play back at the same rate (standard speed), the scene plays out normally. But if you shoot at 1,455 frames per second and play back at 24 frames per second, you see the action move much more slowly, giving the distinctive slow-motion effect.

Things to know when using the slow-motion effect

With the specific instructions above, you can make a good-looking slow video using the slow-motion effect. While shooting slow video, though, keep a few things in mind:

Use a smartphone with a high FPS

When shooting slow-motion video, prefer a device with a high FPS. FPS is the number of frames shown per second while shooting. The higher a device's FPS, the sharper the images it records, and the smoother and better the final video.

The standard frame rate for film is around 24 FPS. At this rate, a sequence of images passes quickly, tricking the brain into seeing fast movement in front of the eyes.

Choose a suitable shutter speed and lighting for slow motion

Shutter speed is the length of time the shutter of a camcorder or camera stays open, controlling how much light comes in and avoiding blur. This principle matters because it creates the illusion of motion in video. When everything comes together too clearly and sharply, the video can feel stiff and unreal to viewers.

In addition, the frame rate, meaning the ratio between frames per second and shutter speed, decides how smooth the video is. For example, when shooting at 24 FPS, the ideal shutter speed is 1/48. If you raise the frame rate to 48 FPS, the shutter speed should be 1/96 to keep the footage even and realistic.

Combine slow-motion shooting with editing

The last tip: slow-motion video needs editing to turn out best. Besides the built-in slow-motion mode, another way to get this effect is to record at standard speed, for example 24 FPS, then slow the footage down by about 50% compared with the original. This gives you more flexibility to set the speed as you want for your own purposes.

When shooting slow-motion video, also watch battery drain and storage use, which are major factors in device performance. Make a habit of checking the battery and free storage before you start so everything goes smoothly. And for good quality, especially when there is no stabilization mode, hold the phone steady or use video-shooting support gear.

That is the information to answer your questions about what slow motion is some notes on slow video mode. We hope this article helps you understand the slow-motion effect and how to edit slow-motion video on a phone. Remember to apply the techniques and tips above to get the best-quality videos.
