2-Perforation movements

ARRI recently released new and improved 2-Perforation movements for the ARRICAM Studio, ARRICAM Lite and ARRIFLEX 235 cameras. These movements can be quickly and repeatedly exchanged with 3 or 4-Perforation movements by qualified technicians, bringing unique production benefits.

The ARRI 2-Perforation movements offer budget-conscious productions an economical route to the image quality of 35 mm. With a native aspect ratio of 2.39:1, 2-Perforation delivers a cinematic, widescreen look that takes advantage of the full width of a 35 mm frame. As film is advanced by two perforations instead of the traditional four, previously unused space between frames is eliminated and so both film stock and film processing costs are approximately halved.

A 2-Perforation pipeline involves no extra work or expense once the decision to go through a DI has been taken; the ARRISCAN film scanner, for example, can scan 2-Perforation material just as easily as 3 or 4-Perforation footage. It is a simple matter to create a normal anamorphic release print from scanned 2-Perforation images.

2-Perforation also allows for longer individual takes than conventional 35 mm, as each roll of film effectively lasts twice as long. One production that has already taken advantage of this is the Caméra d'Or-winning Hunger, on which cinematographer Sean Bobbitt, BSC shot an entire scene in a single, incredibly tense, 20-minute take. "I don't know of any other film format that we could have done that in," says Bobbitt. 

It saves time, it saves money and you don't have to interrupt performances.

Clearly 2-Perforation offers benefits as a widescreen format for feature films, but many television productions are also taking advantage of its cost savings and image quality. "You still have the depth, the tonality, the highlights, the color range and the subtlety of 35 mm, as well as the cameras, accessories and lens ranges," says cinematographer Adam Suschitzky, who shot the BBC mini-series Emma with ARRI 2-Perforation cameras. "It saves time, it saves money and you don't have to interrupt performances."

An ARRICAM Studio fitted with the new 2-Perforation movement can achieve running speeds of 1 – 60 fps forwards and 24 fps in reverse, while the Lite reaches 48 fps forwards and 24 fps in reverse. The ARRIFLEX 235 will run to 75 fps (forwards only) and all three cameras can utilize their full range of shutter opening options.
