In these days of HD vs Film debate, 3Perf/pict is the future of film origination : image quality up, cost down. Slight modifications to cameras and rush projectors induce considerable reduction of film origination costs. Any off the shelf 35mm rawstock can be used in a 3Perf/picture camera (after modification of the regular 4Perf pulldown claw movement). By eliminating the interimage waste, 3Perf pulldown reduces negative, rush and interpositive stock consumption as well as their associated processing costs by 25%.
Like Super16, 3Perf negatives must go through either a 'Digital' or 'Straight Optical' transfer to deliver standard 4Perf prints for theater distribution.
Since the 'original neg to release print' path is no longer following the 'contact-print' process, it is no longer necessary to preserve - and waste - the sound track space, on the original image. It becomes wiser to shoot 'Super35' and use the complete 'perf to perf' silver halide real estate.
The Super35 1.85:1 images occupy 324 mm2 instead of the 273 mm2 stored on a 1.85 cropped Academy frame (a 25% bonus). Note that the Super35 1.85:1 images perfectly fit the field coverage of standard zooms (Ø 27.2 mm).
It brings a 33% increase of the apparent length of the magazines: a 400 foot roll lasts for about six minutes instead of four &1/2 in 4perf. Camera noise is noticably reduced (eg an Aaton 35 becomes virtually noiseless) .
Short ends are reduced by an average of 4%. Because of the larger image -for the same apparent graininess-, faster stocks can be used, which means lighter lighting fixtures. A two hour film - considering an average twelve for one ratio - can be made with 220 rolls instead of 330, i.e. 27.000 meters instead of 40.000.
Film Rushes :
Kinoton projectors can be instantly switched to 3Perf for rushes projection and audio-mixing.
FDL-90, Spirit, C-Reality, Millennium telecines scan 3Perf negatives. Aaton-Keylink telecine code readers handle 3Perf Keycode
Avid FilmComposers directly deliver 3Perf negative cut lists Aaton Edilite (software) makes pull and cut lists from the video EDLs delivered by simple editing systems such as FinalCutPro.
