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
rd
parties, permitting
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 cam-
era. The optical coverage it provides is equivalent to S16 mm. Hence, the maximum recording resolution
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 provides
variable frame rate imaging over 1- 30fps in 4K, 1-60fps in 3K resolution, and 1-120fps in 2K resolution
record modes.
Native color balance for the MYSTERIUM sensor is 5,000 degrees Kelvin, but may be electronically com-
pensated for any color temperature in the range 1,700 to 10,000 Kelvin. White Balance presets are availa-
ble for Tungsten (3200K) and Daylight (5600K) lighting; the camera may also calculate a color neutralizing
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 pixels
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.
