Sony this week unveiled its new Sony XDCAM HD system including two new camcorders and two decks. The same Professional Disc media used in the standard definition version of the XDCAM system is also compatible with the new HD version. Now, professional users can record up to two hours of high definition content on the versatile optical media, maintaining their workflow continuity by combining HD resolution with the same IT-based benefits.
The two XDCAM HD camcorders - models PDW-F330 and PDW-F350 - both offer the production features that professional users need, such as true 24P recording in SD or HD, interval recording, and slow shutter.
The PDW-F350 additionally offers true variable frame rate recording capabilities; also commonly known as "over-cranking" and "under-cranking" or "slow-motion/fast motion" functionality.
The PDW-F350 enables variable frame rate recording at a range of frame rates from four frames per second (fps) to 60 fps in one frame increments. For example, when viewed at 24 fps, four fps yields motion six times faster than normal. In comparison, 60 fps yields motion at 40 percent normal speed. These effects can be played back in the camera or on a Sony optical deck, without the need for any additional special processing through a non-linear editing system or converter.
The PDW-F350 also enables true 24P, 25P and 30P image capture, without any additional conversion required.
The XDCAM HD products offer the flexibility of recording 1080i video in three data recording rates: 25 Mbps, plus 35 Mbps and 18 Mbps. The system records high-definition content to Sony's existing Professional Disc single-layer media using an HD MPEG-2 Long GOP video compression codec.
The camcorders use three half-inch CCD 1.5 megapixel imagers with a variety of lenses from major manufacturers available.
The PDW-F70 and PDW-F30 decks enable high-speed data transfer between compatible nonlinear devices. Both decks up-convert XDCAM standard definition content recorded in the DVCAM™ format to 1080i high definition at output, and all XDCAM HD camcorders and decks can down-convert HD material to standard definition in anamorphic, letterboxed or 4:3 format.
Based on blue-laser technology, the XDCAM system's Professional Disc media offers unique benefits in terms of split-second random access to footage in the field or during the post process, and multi-format flexibility and flexible record times (approximately 120 minutes or more of HD content at 18 Mbps or 85 minutes of SD DVCAM at 25 Mps).
The Sony Professional Disc media is re-usable up to 1,000 read/write cycles and up to 10,000 read/write cycles in ideal conditions, based on Sony's own testing. The greater number of repeat recordings possible with the XDCAM Professional Disc allows a production crew to re-use it more often than a videotape and without experiencing degradation after multiple uses of the media.
The following XDCAM HD products are planned to be available in March 2006, with suggested list pricing of:
*
PDW-F350 camcorder: $25,800
*
PDW-F330 camcorder: $16,800
*
PDW-F70 deck: $15,990
