The full frame video myth
Jan 11, 2013

There are a couple of myths regarding Full Frame video shooting, they need some exploration.

Movies shot on 35mm film have been using the so called Super35 format for the last 30 years or so. Exposed on film is an area of 24.89 mm × 18.66 mm. A film camera takes the film down the width of a 35mm stock while a photo camera takes it sideways, thus the 36mm wide format and the 24mm high which allows for sprockets top and bottom.

Professional video Film look cameras don’t shoot Full Frame. Abel Cine furnishes this charts: http://blog.abelcine.com/wp-content/uploads/2012/05/35mm_Digital_SensorsWEB_2012MAY.pdf that is quite intersting.

First let’s look at what is the accepted standard of top of the line cameras in the movie world, the Arri Alexa. The chip size is even less than the Super35 format, idem for the Sony Cam, the Red.

There is a good reason why the Arri’s are the standard worldwide: LENSES! Cinematographers are more or less camera agnostic (a different story for cameramen and assistants) but they are lens lovers. Now they cannot buy Panavision lenses (only rentals) but they can own their own lens and some do. And most of these lenses are PL mount . Most are Cooke. These lenses are not cheap, making one is time and resources consuming.

All of this is interesting if not for the simple fact that most of what you see as live HD video on broadcast tv around the world is not even shot on the Super35 format but on the much smaller ½” and 2/3” one. Mind you with 3 chips… Why? Rolling Shutters on the Bayer filter, you know the jello effect.

Hope this help some who want to know… The others already know everything!
