Camera and Lighting - Frame rate research

Frame rate is the speed at which those images are shown, or how fast you “flip” through the book and it’s usually expressed as “frames per second,” or FPS. Each image represents a frame, so if a video is captured and played back at 24fps, that means each second of video shows 24 distinct still images.

The speed at which they’re shown tricks your brain into perceiving smooth motion.
Why does frame rate matter?

Frame rate greatly impacts the style and viewing experience of a video. Different frame rates yield different viewing experiences, and choosing a frame rate often means choosing between things such as how realistic you want your video to look, or whether or not you plan to use techniques such as slow motion or motion blur effects.

For example, movies are usually displayed at 24fps, since this frame rate is similar to how we see the world, and creates a very cinematic look. Video that’s broadcast live or video with a lot of motion, such as a sporting event or video game recording, will often have a higher frame rate, as there’s a lot happening at once and a higher frame rate keeps the motion smooth and the details crisp.

On the other hand, people who create animated GIFs will often sacrifice detail for a smaller file size and choose a low frame rate.

Frame rate doesn't effect the amount of light the camera receives however it works in conjunction with the shutter speed to create a smooth image.
