An Overview of Frame Rate
Frame rate usually refers to the number of consecutive images captured or displayed per unit time. It is expressed in fps, which refers to the rate at which a system, like a GPU (Graphics Processing Unit), can generate frames in a specified amount of time. By the way, the common frame rates in daily life are 24fps, 25fps, 30fps, 60fps, and more.
How Frame Rate Affects Video Size
The number of frames per unit time determines the smoothness of an animation. Generally speaking, the higher the frame rate, the more details and information the animation contains, which translates into more data and ultimately improves the video quality.
Many factors affect the size of image videos, usually including codec, resolution, and bit rate. In fact, frame rate affects the size of the video as well. If you want to reduce the video size, you can lower the frame rate.
