Hi everyone,

Studio Daily's got a great video of Ari and David Newman explaining the workings of the camera and the Cineform RAW workflow.

Silicon Imaging SI-1920HDVR

The Camera That Defines Its Own Workflow

By Bryant Frazer

May 8, 2006 Source: Film & Video

As image-quality requirements bump up against bandwidth-based reality, itís more clear now than ever that when you select a camera youíre already starting to determine your optimal post-production process. Working in cooperation with the codec experts at CineForm (theyíre the guys who first brought you HDV editing in Adobe Premiere Pro), Silicon Imaging has a new camera that defines your entire workflow from the moment you hit record. The camera itself uses a single 2/3-inch CMOS chip with a 12-bit A/D converter and has four hours of recording (to a hot-swappable 160 GB USB 2.0 notebook HDD) on board. Whatís radically different here is that it records files using a 10-bit wavelet-based codec (running at 96 Mbps) from CineForm that maintains RAW Bayer data all the way through the render process ó the color matrix is handled as metadata in the stream, so the codec wonít allow you to make any truly destructive color-space changes as you work. The camera records 1080p at 24, 25 and 30 fps, and 720p up to 72 fps. Lens options include PL-mounts as well as F- and C-mounts, and the camera head can even be detached and linked up to the rest of the system vie Gigabit Ethernet. Maybe the best part? Itíll be less than $20,000. Look for it as early as the third quarter.

(Thanks in Advanced)

The camera records RAW (digital negatives). The final output after demosaic can be 4:4:4 or 4:2:2 or Windows Media Video HD or any other output format you can select in Adobe Premier (and QT application in the near future).

Impressive!, seen a clip of the girl in the graveyard, Wow, dynamic range is amazing, the shallow DOF, and the general sharpness of the lens, when I watched it, it looked like film, The only time any Digital video looked like film is when it was attached to a 35mm adaptor and had considerable CC done.

You should also consider downloading the sample RAW (.DNG) file, to see the amount of latitude you have in post with our footage:
