The Genesis is Panavision's high-end digital movie camera, which uses a proprietary, full frame 35 mm-width, 1.78:1 (16:9) aspect ratio, 12.4-megapixel, RGB filtered CCD.[1] It was first used by a feature crew to shoot Bryan Singer's Superman Returns and was shortly followed up thereafter by the World War I film Flyboys. However, the CGI-heavy nature of these two movies meant that ultimately the comedy Scary Movie 4 was the first theatrically released feature sourced primarily from the Genesis camera.

Background

Unlike the 2/3" 3-CCD imaging system used in Sony's HDW-F900 CineAlta camera (used in Attack of the Clones), the Genesis uses a single 12.4 megapixel CCD chip with the same width as a Super 35 mm film frame. The "Panavized" CineAltas did not use Panavision's existing range of 35 mm film lenses and have different depth-of-field characteristics.

Most photographic lenses designed for film cameras cannot be adapted to work on 3-chip video cameras. In many cases, the prism block simply leaves no room for the rear element of the lens. In cases where the lens does fit, the resulting optical aberrations created by the prism (primarily spherical) would destroy image quality. Apart from this, the sensors on a "2/3 inch" video camera are closer in size to a 16 mm film frame and so would produce a similar depth of field.

Panavision originally tried to overcome this problem with optical adaptors that fit between the cine lens and the video camera, but these have all produced an unacceptable drop in image quality. Most productions using the Sony HDCAM cameras therefore used lenses from Zeiss, Angenieux, Canon or Fujinon.

Apart from this, there were a number of operational problems with both the lenses and cameras used for Attack of the Clones, and so for Star Wars: Episode III – Revenge of the Sith, George Lucas severed his long-standing relationship with Panavision in 2003, obtaining newer-model Sony HDC-F950 cameras and lenses from Plus8Digital instead.

In an attempt to address these and other problems, Panavision followed this up in 2004 with the Genesis, a full bandwidth (4:4:4)[2] camera with improved colorimetry and sensitometry-related specs and, probably most importantly, a Super 35 mm film-sized recording area, thus making it focally compatible with regular Cine Primo lenses and giving a true 35 mm depth of field.

Technical specification

The Genesis uses a 12.4 megapixel CCD chip, arranged in a 5760x2160 horizontally RGB filtered array. The vertical resolution is cut in half to 1080 by pixel binning, so the final output pixel resolution is 1920x1080, about 2/3 the resolution of a 2k film scan. The chip has an HDTV-style 16:9 (1.78:1) aspect ratio, similar in size to Super35 3-Perf film. The CCD active area is .930 in. x .523 in. This is a significant breakthrough in that it allows just about any Panavision spherical 35 mm cine lens to be used. The main imaging module of the Genesis is made by Sony, but the exact relationship between the two companies is unclear, since their joint partnership was dissolved in 2004 with Panavision's re-purchase of the 8% shareholding Sony bought in 2000.

The Genesis can record in a custom Panalog color space, which is a log color space that is also 4:4:4, unlike traditional HD. The tone-curve is different from the Cineon log format used for film post-production, but preserves highlight detail that would be lost with typical video gamma correction.

There have also been numerous complaints about the small black and white viewfinders. B&W finders are actually strongly preferred by generations of broadcast camera operators, who understand that a high resolution black & white finder is a very highly refined instrument. It has about 3 times the resolution of a color finder, which makes achieving critical focus easier. An influx of camera operators from the film industry however, has created demand for a color viewfinder. To address this, Panavision uses the Sony HDVF-C30W TFT color LCD viewfinder (960x540 pixels), which is compatible with both the CineAlta and the Genesis cameras. A Digital cinema camera competitor to the Genesis, the D-20, incorporates a reflex optical viewfinder to address this concern. Other similar HD-resolution cameras are the Sony F35, ARRI Alexa, and RedOne.
