What does frame rate mean?

Simply put, a frame rate is the number of frames of an image transmitted in one second, which can also be interpreted as the number of times the graphics processor is able to refresh the image per second, and is usually expressed in fps (Frames Per Second). Each frame is a static image, and displaying frames in rapid succession creates the illusion of motion. Higher frame rates result in smoother, more realistic animation. The more frames per second (fps), the smoother the displayed motion.

Generally speaking, 30fps is acceptable, so the minimum fps to avoid choppy motion is 30. In addition to 30fps, some computer video formats, such as AVI, can only deliver 15 frames per second. The reason why we can use the camera to see continuous images is because the image sensor is constantly taking in images and transmitting them to the screen, and when the transmission speed reaches a certain level, the human eye is unable to recognize the time gaps between the images, so everyone can see continuous motion.
