THEORY OF OPERATION

The RED ONE™ Digital Cinema camera provides high performance digital imaging over a wide range of
frame rates and optical formats including Super 35mm, 35mm and Super16mm. The camera is supplied
as standard with a PL mount, and may be configured with 19 mm rods to accommodate most cinemato-
graphy lenses, matte boxes and follow focus systems. Adaptors for 15mm offset studio and 15mm
lightweight rods are also available.
In addition to compatibility with existing PL mount cinematography lenses; a select range of S35/35mm
format PL mount prime and zoom lenses are available from RED DIGITAL CINEMA™.
Other lens mounts, including Canon FD, and Nikon F are available from RED™ and 3 parties, permitting
rd
the use of Nikkor and Canon photographic lenses. To use these mounts the PL mount must be removed.
It is recommended that this should be done only in a dust-free environment, as the sensor and optical
path will be exposed to the elements during this process.
A B4 mount to PL mount adaptor is also available to permit use of 2/3" HD lenses on the RED ONE™
camera. The optical coverage it provides is equivalent to S16 mm. Hence, the maximum recording resolu-
tion with these lenses will be 2K RAW. (2048 x 1152 pixel progressive scan)
MYSTERIUM® SENSOR
The MYSTERIUM® sensor has been specifically designed for use with the RED ONE™ camera, and pro-
vides variable frame rate imaging over 1- 30fps in 4K, 1-60fps in 3K resolution, and 1-120fps in 2K resolu-
tion record modes.
Native color balance for the MYSTERIUM® sensor is 5,000 degrees Kelvin, but may be electronically
compensated for any color temperature in the range 1,700 to 10,000 Kelvin. White Balance presets are
available for Tungsten (3200K) and Daylight (5600K) lighting; the camera may also calculate a color neu-
tralizing White Balance value using a standard white card technique.
MYSTERIUM® includes integrated 12-bit resolution analog to digital conversion, capable of delivering up
to 11 stops of dynamic range when operating in daylight at a sensitivity of 320 ISO.

IMAGE PROCESSING

Images received from the MYSTERIUM® sensor are formatted as pixel defect corrected (but not color
processed) 12-bit RAW data - similar in image quality to a high end digital stills camera.
The sequence of 12-bit RAW images received from the sensor is compressed using proprietary wavelet
based REDCODE™ RAW compression. The RAW data recorded is independent of the RGB signal moni-
tored from the monitoring path. ISO, white balance or other RGB color space adjustments made to the
monitoring path are not burned into the recorded 12-bit RAW data.
Images can be stored on a high-speed Compact Flash, RED-DRIVE® or RED-RAM® media.
The camera's monitoring path converts 12-bit RAW sensor data white balanced 10-bit 1280 x 720 pixel
RGB 4:4:4 video. This signal may be modified using ISO, white balance or other RGB color space adjust-
ments and provides monitor feeds for the RED™ EVF, RED™ LCD, Preview HD-SDI and HDMI outputs.
