How to create good slow motions

What is a slow motion?

Slow motion is a cinematic technique that reduces the speed at which video frames are played back, making fast-moving actions appear significantly slower. This effect can add dramatic emphasis to a particular scene, highlight details that are usually missed at normal speed, and create a visually stunning experience for the viewer. It's commonly used in sports replays, action sequences in movies, and nature documentaries to emphasize moments that would otherwise be too quick for the naked eye to fully appreciate. Read more on Wikipedia about slow motion.

What is required for a good slow motion?

For a slow motion to appear smooth and not like a slideshow, high frame rate footage is essential. The more frames per second (fps) a video has, the smoother the slow motion will be when the playback speed is reduced. Standard videos are often shot at 24 to 30 fps, but for effective slow motion, shooting at higher frame rates like 60 fps, 120 fps, or even higher is recommended. Additionally, sufficient lighting is crucial because higher frame rates require faster shutter speeds, which in turn necessitate more light to maintain image quality.

How do you make a slow motion? 

Making a slow motion involves capturing or converting video at a high frame rate and then playing it back at a standard frame rate. When recording, many modern cameras and smartphones offer a slow-motion mode that automatically does this for you. If recording in normal mode, ensure your device is set to capture at a high frame rate. After recording, you can use video editing software to slow down the playback speed of your footage, effectively creating the slow-motion effect.

If you do not want to record video at a high frame rate, create it as usual in normal speed. There are many video enhancing and editing applications that will convert your video into a slow motion.

How do I convert a normal video into a slow motion?

To convert an existing video into slow motion, you'll need video editing software capable of time remapping or speed adjustment. Import your video into the software, and look for an option to reduce the playback speed or increase the duration of the clip. Some software might offer advanced options to interpolate frames with AI, ensuring smoother transitions between existing frames, especially if the original video wasn't recorded at a high frame rate. After adjusting the speed to your liking, preview the slow-motion effect to ensure it meets your expectations before exporting the final video. Keep in mind that converting standard frame rate videos into slow motion without AI frame interpolation might not yield results as smooth as footage originally shot for slow motion.

Which applications convert videos into slow motions?

There are many online video editors and software applications that support converting videos into slow motions. Here are some of the best ones:

1. Audials Vision

Audials Vision is a Windows software to improve video quality with AI. It has an option to change the video speed and to create silky-smooth slow motions. To ensure that the framerate is high enough so that the video does not jitter or show slideshow effects, Audials Vision applies frame interpolation using artificial intelligence. That means that the AI calculates and adds additional frames to the video. If you want to get a video of half the speed (50% speed), you need to preset the double framerate of the original video. If you need  a 25% speed, quadruple the framerate with Audials Vision.

Supported speeds: 10%, 15%, 20%, 30%, 50%, 75%, 100%, 120%, 150%, 200%. To obtain a slow motion, choose a percentage that is lower than 100%, otherwise you will get a timelapse.

Besides slow motions, Audials Vision is an AI video enhancer that increases the video resolution and video quality with AI up to 4K. It converts videos into HDR so that you will enjoy imressing contrasts and colors on your HDR TV or HDR monitor. A video cutter and cropper, a subtitle search engine and a video manager to manage videos on PC and mobile devices is included, too. 

2. CyberLink PowerDirector

CyberLink PowerDirector for Windows or Mac has an interesting feature for slow motion creation: You can preset a desired duration smaller than the original duration. Alternatively, you can preset the video speed with a slider similarly to other apps. It seems that PowerDirector does not apply AI for slo-mos. But there are other AI features: Converting speech to text, generating pictures, removing background and others.

3. Magix Movie Studio 2024 Platinum

Among many usecases, Magix Movie Studio 2024 Platinum creates slow motion videos at 0.25x, 0.5x, or 0.75x speed or fast motions at up to 4x speed. Alternatively, you can select a duration smaller than the original duration and the software will calculate the slo-mo. It seems that AI is not used to interpolate frames. Movie Studio has many effects, transitions, color settings and other editing features.

4. Adobe Express

Adobe Express is a free online slow motion converter that supports 25%, 50%, 100%, 150% and 200% speed. To obtain a slow motion, choose a percentage that is lower than 100%. As Adobe does not mention whether this feature is AI supported, you could see artifacts for very low speed.

Adobe Express also can be used to trim, merge and crop videos, to resize them, to add captions or to convert them into a GIF.

5. Kapwing

Kapwing is a comprehensive online video editor that partly uses AI to help edit videos fast. One of the features is creating a slow motion or timelapse. Kapwing supports 0.25x speed up to 4x speed. You can select the desired speed with a slider with an accuracy of 0.1x. It seems that AI is not applied for changing speed.

Kapwing will be practical for many other usecases like adjusting brightness, contrast and saturation, cutting and cropping, reversing, adding elements and images, texts an subtitles. Among AI features, Kapwing has Smart Cut and Clean Audio for optimizing the audio track of the video.

6. Canva

Canva has a free app for turning videos into slow motions. It is free, but you will need to register before uploading a video. Apparantly, AI frame interpolation is not available. Depending on the plan, Canva has more editing features like translating, drawing, turning text into video, and many more.

7. Flixier

With Flixier, you can create slow motions and timelapses online with 0.5x, 1.0x, 1.5x and 2.0x speed. To choose a speed more exactly or a higher speed than 2x, you can use the slider. Flixier does not support AI frame interpolation for smooth movements.

In addition to slo-mo creation, Flixier can be used to blur, cut and crop videos, to add texts and subtitles, and much more. 

8. Clideo

On the Clideo online platform, you can create slo mos and timelapses at 0.25x, 0.5x, 0.75x, 1.25x, 1.5x and 2x speed. In case you need to set the speed more exactly or need up to 4x speed, you can use the slider. AI frame interpolation is not mentioned.

On Clideo, you can adjust lighting and colors, add text, split screen, cut, crop and compress videos, and much more.

9. Slow motion video fast&slow mo

You have shot a video with your smartphone and don't want to edit it on a PC? Then you can use the Android app Slow motion video fast&slow mo to adjust the video speed. This mobile app supports the following speeds: 0.25x, 0.5x, 1.0x, 2.0x, 4.0. Seemingly there is no frame interpolation with AI. If you wish, you can add a black and white, a polaroid or a bleached filter or insert music.
