Film and Video (Digital and Analogue)

Film
Film is usually filmed in Digital. On old fashioned film called, 'Film Stock'; you have to load it up in complete darkness. Otherwise the light in the frames will not be shown properly. Making film is very expensive, film needs to be developed and it has to have light shone through it so it can be projected. Whereas on video, it is captured on magnetic tape and also scanned completely back over a 'Play-head'. Film shoots at 24 frames per second, but Video shoots frames per second that are interlaced. This is actually two sets of half images 30 times a second.

Video
For video, it is a normal electronic medium that is only used for analogue recording, analogue broadcasting and analogue copying. As a student with hardly any good budget, you can get a ordinary camera and start shooting you're shots. After that you can go to your computer or laptop, put all the shots you have on there and if you have a editing window; you can edit the shots. Not even that, but you can edit sound, light, motion speed and more. This sort of video is not Analogue, it is Digital.

Analogue and Digital
The Analogue signal is a continuous signal which only represents physical measurements. However on Digital, the signals are discrete time signals generated by digital modulation. Analogue can be used in analogue devices only, but they are best suited for audio and video transmission. On Digital are best suited for digital electronics and computing.
