There were videos* before computers.

*Not really, but you could film stuff and display it.

Film is a chemical medium for storage of images.

Video is an electronic process for capturing images and displaying them.

Before digital video there was analogue video, and analogue video was perfectly possible without digital sampling, or computers. Heck, video pre-dates silicon chips and used to be done with CRTs and valves.
