"120 frames per second" (fps) refers to the rate at which consecutive images, or frames, are displayed in a video. This means that 120 individual images are shown every second, resulting in smoother motion and clearer visuals compared to lower frame rates, such as 30 fps or 60 fps. Higher frame rates are particularly beneficial in fast-paced scenes, like in video games or action movies. Using 120 fps can enhance the viewing experience, making movements appear more fluid and reducing motion blur. Many modern televisions and monitors support this frame rate, allowing for a more immersive experience, especially in virtual reality and high-speed sports broadcasts.
