How Does Film Sound Work?

When you go to a movie theatre, producing perfectly synched sound that completely envelopes the room isn’t as simple as just playing an audio track. There are two forms of analog sound: optical process and magnetic. In the early days of movies, many films used an optical process to create sound synched to the film. In the optical process, a clear line is recorded into one side of a film strip, and the line’s width changes according to the film’s sound frequency. A light shines through this strip, and the light transforms into an electrical current thanks to a photocell. […]

Panavision a History – 8mm projector & equipment

At the end of many movies, one will see “filmed in Panavision” scroll by along with the rest of the credits. When a film production uses Panavision’s anamorphic lenses, they are contractually obligated to use the phrase in their credits. Anamorphic format is both a form of projection that requires an anamorphic lens to keep the aspect ratio of 2:1 as well as the technique of creating a widescreen picture on 35 mm film.

Slow Motion Filming – video production videos

We all know that high speed cameras can create gorgeous slow-motion effects when it comes to filmmaking. But that’s not all that’s involved. The Marmalade, a film company that specializes in slow-motion filming, has released a beautiful and informative new video on their techniques. For example, before the company knows whether or not flat storyboard drawings will work on film, they head to their studio and test out their ideas. They repeatedly test all of their processes – bottles crashing to the floor, for example, to be sure that the idea transfers well over to film. It’s not all about […]

The Hollywood Film Restoration Process

When classic movies are re-released, they’re often advertised as being “restored”. What does this mean, and how do they do this? Universal, for example, is marking its 100th anniversary this year and has been restoring films since the 1990s. Technology is available today that allows film studios to go back to older movies and remove any small imperfections in the original film, not to detract from the original vision of the filmmakers but to make these imperfections less distracting and visible. Using the film’s original camera negative, every single frame of a film is turned into a digital frame that […]
