Motion smoothing is a technology used in televisions and displays to enhance the fluidity of motion in video content. It works by inserting additional frames between the original frames of a video, which can make fast-moving scenes appear smoother and reduce motion blur. This feature is often found in modern LED TVs and OLED displays. While motion smoothing can improve the viewing experience for sports and action movies, some viewers find it can create an unnatural look, often referred to as the "soap opera effect." This effect occurs because the technology can make films appear more like video recordings rather than traditional cinematic presentations.
