Motion illusion is an optical illusion in which a static image appears to be moving due to cognitive effects of interacting color contrasts and shape positioning
Persistence of Vision
Persistence of vision refers to the optical illusion whereby multiple discrete images blend into a single image in the human mind and believed to be the explanation for motion perception in cinema and animated films.
Beta Movement
The beta movement is an optical illusion, first described by Max Wertheimer in 1912, whereby a series of static images on a screen creates the illusion of a smoothly flowing scene. This occurs when the frame rate is greater than 10 to 12 separate images per second.
Frame Rate (FPS)
Frame rate, also known as frame frequency, is the frequency (rate) at which an imaging device displays consecutive images called frames. The term applies equally to film and video cameras, computer graphics, and motion capture systems. Frame rate is expressed in frames per second (FPS).
This shows the difference between 12, 30, 60 and 120 FPS
Difference between 30 and 60 FPS, this examples shows a sword attack.
Suspension of Disbelief
The term suspension of disbelief or willing suspension of disbelief has been defined as a willingness to suspend one's critical faculties and believe the unbelievable; sacrifice of realism and logic for the sake of enjoyment.
The phrase suspension of disbelief came to be used more loosely in the 20th century, often used to imply that the burden was on the reader rather
than the writer to achieve it.
