Accom demonstrates uncompressed portable video storage
May 5, 2003
Accom is now offering a portable digital cinematography storage solution based on an uncompressed RGB data handling chain that’s optimized for high image quality and post-production applications.
Capturing data in real-time from the new generation of RGB HD cameras from Thomson and Sony, the WSD/HDi records in 10-bit log 4:4:4 and provides true color log-corrected HD monitoring of the camera output.
Based on the company's WSD/HDi multi-format disk recorder, the new device offers a portable solution for storing footage and delivering digital data to post facilities, a remote production review capability for digital dailies, and an encoding platform for the creation of high-resolution previews, trailers, and DVD content.
Capturing data in real-time from the new generation of RGB HD cameras from Thomson and Sony, the WSD/HDi records in 10-bit log 4:4:4 and provides true color log-corrected HD monitoring of the camera output. During the recording of camera output to the WSD/HDi’s internal storage, footage is simultaneously converted and exported as DPX format files to portable external drives via a high-speed USB link. With current technology up to 25 minutes of HD 24P uncompressed RGB can be stored on each portable disk.
For facilities, delivery of the footage in uncompressed DPX format solves the problems usually associated with HD footage recorded to tape, where compression complicates post-production operations such as matting and color correction. During post, a WSD/HDi attached to the post facility’s network can be set up to automatically pull completed frames off the network via a Gigabit Ethernet link as they become available, and optionally convert them to YUV and lay off to tape for broadcast.
With WSD/HDi’s built-in Microsoft Windows Media Encoder 9 Series capability, footage recorded on the WSD/HDi can be encoded for remote delivery as digital dailies, either direct from the location or from a post facility to allow directors to review post-produced shots while still on set. Customizable encoding profiles allow shots to be delivered in a range of file sizes, from compact VHS-quality dailies, up to 7Mbps (megabit per second) HD clips for critical production review, web-trailers or DVD content.
