FPS stands for "frames per second" and refers to the number of individual video frames that a camera captures per second. The frame rate determines the smoothness of a video, and the most commonly used frame rate used in films is 24 frames per second. For the internet, it’s 30FPS, and it is this rate that ensures a smooth progression of your videos without any pictures stuttering. A higher frame rate, such as 60fps, is used to record films and applied for slow motion. It captures more frames, which allows you to capture action footage with ultra-realism and video that will look smooth when played back in slow-motion. However, when choosing a higher frame rate, it is important to keep in mind that the slower the slow motion will be.

In summary, FPS in a camera refers to the number of frames that a camera captures per second, and it determines the smoothness of a video. The most commonly used frame rate in films is 24 frames per second, while 30fps is standard for web-based videos. A higher frame rate, such as 60fps, is used to record films and applied for slow motion.
