You will already know the concept of these images moving so fast that they appear to the viewer as moving images. A camera records a set number of frames per second (FPS) along with masses of metadata.

Since the frame rate is a set number of FPS, when it is increased, the smoothness of the video improves, and any blurriness will likely be removed. The downside is that the file size increases in terms of the storage space on the computer.

Historically, 30 FPS became the norm for analog TV broadcasts in North America, Japan, and South America. Europe and Africa adopted 25 FPS due to the different frequencies in the mains power supply – 60 Hz and 50 Hz, respectively.

There is another important reason that frame rates should...
