Film and Video, Analogue and Digital

Film and Video: -
Film and video whats the difference? It’s become an ongoing debate among producers as to whether or not one medium is really better than the other. But while there are several differences between video and film, many times the deciding factor between who uses video and who uses film is cost.

Film is a chemical medium primarily made from celluloid, Video is a electronic medium, video is a analogue recording system but digital video is a digital recording system.

Digital cinematography is the process of capturing motion pictures as digital video images. digital capture is  changing ​data, photos, and ​videos into a ​form that can be ​processed by a ​computer.


Film needs to be developed and have light shone through it in order to be projected, video is captured on magnetic tape and scanned back over a play head. A tape can only reach a certain resolution before it starts to degrade in quality. Film, on the other hand, can become as large as the distance from projector to screen allows.

While cost plays a major role in the use of video or film, the one of the major arguments comes from the quality that each medium can display. Because film simply captures light waves, its creating lines of depth and color so it looks smooth and soft when projected, even at large sizes compared to the quality that video can display.

Analogue and Digital: -
The simplest way to describe analogue and digital is to say 'signals' Analogue and digital signals are used to transmit information, usually through electric signals. In both these technologies, the information, such as any audio or video, is transformed into electric signals. 

The difference between analogue and digital technology is that in analogue technology, information is translated into electric pulses of varying amplitude, while in digital technology, translation of information is into binary format, zeros and ones, where each bit is representative of two distinct amplitudes.
