What Is Slow Motion
Before you make a slow motion video, it’s necessary to make clear what slow motion is. Slow motion, also known as slo-mo or slow-mo, is a filmmaking effect with which time appears to be slowed down. If you make a video slow motion, you will add drama to a scene and allow viewers to perceive more details than a video played at normal speed. This can be achieved by recording with high-speed camera and then playing the video at a standard rate, say 30 fps, or using a video editing software in post-production.
