Film v's Video; video and film are two very different forms of media one being shot on a big and bulky camera that costs the earth and then makes you wait whilst it develops before you can see your product, whereas with video you can shoot your video on DSLR cameras that you can then play back your content on and see whether the shot needs to be taken again so not only does it save time but money also as the equipment is cheaper and you do not have to buy the film also which is saving a lot of money.
'Photographic motion picture film captures an image via a light sensitive chemical surface that reacts to the varying levels of light entering the camera’s lens. The film rolls by the camera’s gate at a uniform rate, usually 24 frames per second, so named because every second 24 different images, or frames, are exposed on the film. When projected, the individual images appear as fluid motion due to a phenomenon called persistence of vision. Once exposed, a roll of film is shipped to a film lab where it is processed in a chemical bath that reveals the image on the light sensitive surface and makes it permanent.'
'As with film cameras, digital cameras rely on light to create an image. However, digital cameras use charged coupled devices, or CCDs, rather than photographic film, to record images. The CCDs record the light rays entering the lens as data and convert that data to an image, which is stored on some sort of physical media (such as a CF card or hard drive). Similar to the film camera, the digital video camera will capture 24 frames per second (or in some cases 30) that, when played back, appear as fluid motion.'.
this is the link to the post where I found the above information as I feel it explains fully what the differences between film and video are:
