Video editing process nowadays is so much easier than it used to be (especially considering XX century).

Here’s something interesting:

All editing now is done digitally on computers and just takes some storage on a hard drive (or tape) but physically it takes very little space and hardly any weight – as a comparison, when Francis Ford Coppola was working on Apocalypse Now (that’s 1979) the material for the film (video and audio) weighed almost 7 tonnes!, and it was 1.2 million feet long!

Here’s another interesting fact, about early non-linear editing this time: image quality of early video editing on Avid was very poor compared to film – 3,000 times less resolution!
