Video assist allows filmmakers to see a take immediately after it’s been shot. Video assist is key simply because it aids the filmmaker in deciding if the take should be shot again, and how. What a lot of people don’t know is that video assist was influenced heavily by Jerry Lewis. The Nutty Professor himself was something special.
When he put together his classic film The Bellboy Jerry Lewis used a video camera to record while filming. This technique did not initially get tagged as video assist; still it was something that created a whole new way to aide directors. The funny thing is that The Bellboy was Jerry’s first directorial effort.
