These very same issues also apply to video games.
A lack of source frames also means motion can be blurred and undetailed.
Whilst it does create enough motion to make the human eye perceive the illusion of a moving image, it does not perform well in certain shots such as panning, tilting and tracking. The problem with this, however, is that 24 frames per second is quite a slow frame rate, given that it is just enough to give the illusion of moving image. Many TV manufacturers are now adding native 24Hz refresh rates to ‘correctly’ display 24p, and pulldown methods to display 25 and 29.97 FPS (PAL and NTSC standards) at 24p. Anything filmed and displayed in 24p will have that filmic type of motion that is so sought after. 24p (usually 23.976 frames per second with progressive scanning) is considered the ‘cinema look’ by many in the industry. 24 FPS became the standard for film between 19 due to the introduction of sound, (it is assumed that the previous fluctuating frame rate would cause changes in audio frequency if synchronised), and to this day has remained so.
In the 1880s silent film was introduced, and with it came video frame rates of between 18-24 frames per second (FPS).
