The full-reatured, all-in-one portable design of the Silicon Imaging SI-2K combines a digital cinema class 2048x1152 resolution camera head, IRIDAS color-management technology, and the power of CineForm RAW™, to deliver a direct-to-disk raw recording platform with unprecedented image quality and shooting flexibility. It's low-noise, high-dynamic range images, with over 11 f-stops of dynamic range via an on-chip 12-bit A/D converter, are freely manipulatable with user-generated IRIDAS .look files, creating a "blank-slate" for the cinematographer to freely express his or her vision. IT-friendly connectivity through integrated 802.11g wireless access, Touchscreen interface, Anton-Bauer battery-powered operation, and up to 4-hours of continuous shooting on a 160GB notebook hard drive round out an impressive array of digital cinema firsts in the industry.
The Silicon Imaging SI-2K uses a single large 16:9 format 2/3” CMOS sensor, with it's design enabling the use of lower-cost 16mm film-style lenses, eliminating the optical aberrations caused by a 3-chip prism assembly. Shooting flexibility is enhanced with its interchangeable optical assembly, supporting the use of high-quality modern cinema PL-mount lenses as well as affordable and compact C-mount lenses. The integral support for 15mm lightweight rods and direct attachment of 19mm ARRI style bridge-plate adapters make the SI-2K an ideal platform for the latest in follow-focus attachments, matte boxes, and other cinema-style gear and accessories. An industry standard, Anton-Bauer Gold-Mount is used for battery power and portable operation. For situations too extreme or space-limited for the camera operator to maintain direct physical operation, the SI-2K features the ability to remotely tether the camera head via gigabit ethernet over long distances while maintaining full control of the camera. The separable camera head's built-in power regulator allows battery operation from 5-17VDC with a miniscule 6W of power consumption. For very long distances, off-the-shelf fiber optic converters can be added to extend distances past the threshold of copper-based gigabit.
The SI-2K captures full resolution, DCI-compliant 2K and 1920 x 1080 progressive-scan 12-bit raw images for use in both digital cinema projection and HD television or optical disk environments. It uses Silicon Imaging's proprietary 48-bit digital processing algorithms to perform adaptive pixel-by-pixel black calibration and color image enhancement.
Standard 2K and 1080P resolutions can be recorded at up to 30fps. Special Effects and off-speed shooting modes include a variety of overcranking and undercranking options. Slow-Motion shots can be captured at speeds up to 72fps in 720P mode, 3-times the nominal 24P film rate. Long-duration events are captured using the time-lapse recording feature or using the long exposure mode, which accumulates light over several frame times to exaggerate motion for streak-style effects.
The SI-2K was used for Slumdog Millionaire, a feature film from Fox Searchlight, directed by Danny Boyle, DP Anthony Dod Mant
