Slow motion is mainly used to amplify movement details, enrich emotional expression, enhance visual appeal, and draw the audience's attention.
Have you ever been immersed in a video with slow motion to the point you thought, "How can I make a video slow motion"? Now you are in the right place. We will provide you with the five best methods to create a video in slow motion.

Part 1. What You Should Know About Slow-Motion Video
A slow-motion video doesn't only mean that your video gets slower, but the frame rate will also greatly increase, or your video will look full of lag. First, you should know that a video consists of many individual images, and how frequently the images are displayed determines the frame rate (also called FPS) of a video. Generally, 24 fps means 24 frames (images) are shown per second.
However, if you only make the video go slower but do not add extra frames, the video will look quite laggy. Therefore, that's why you need a professional method to make a slow-motion video, rather than just slowing down the video.
