The PDW-1500 Compact Deck is a half-rack sized recorder optimized for use with non-linear editing systems. Despite its compact size, this deck offers high-speed data transfers between compatible non-linear devices to create a powerful editing tool for news production.
New "Non-linear" Recording Medium
Professional discs have a natural advantage since they suffer no mechanical contact during recording or playback, making the format ideal for continuous use and re-use (up to 10 000 times!). The Professional Disc is also highly resistant to dust, shock and scratches, packaged in an extremely durable and dust-resistant cartridge. It is resistant to heat, humidity and X-rays– factors that make the Professional Disc ideal for use in harsh field environments, and also allows for long media life and long-term storage (50 Years). Finally, despite all its inherent benefits - Instant access, high speed transfer and exceptional reliability - professional discs still cost the same price as a tape and consequently can be perceived as a media.
With all Sony XDCAM products, a thumbnail is automatically generated to represent each recording made. As is common in non-linear editing systems, these thumbnails allow for instant access and playback of clips. The Essence Marks used in Sony XDCAM products are also a very useful form of metadata, and provide a most effective way of searching for recordings via thumbnail pictures. Essence Marks can be set during the shoot either manually or automatically.
Benefits of Proxy AV Data
Proxy AV Data is a low-resolution, MPEG-4 based version of the full-resolution MPEG IMX/DVCAM stream. When a recording is made, a Proxy AV stream that is time code synchronized with the full-resolution stream, is also recorded automatically on the disc. This Proxy AV Data, which is smaller in size, is easier to work with and can be transferred over common networks at much greaterspeeds. Proxy AV Data is highly effective for tasks where video and sound quality are of less concern, but content delivery speed is essential. The typical benefits of its use include 'Remote Content Browsing' and 'Proxy Editing'.
In the Sony XDCAM Series of products, recordings are made as data files – one for each video or audio clip. This allows material to be handled with great flexibility in an IT-based networked environment – and easily available for copying, transferring, sharing and archiving to other IT-based devices. This file-based recording system also allows material to be viewed directly on a PC linked to the XDCAM decks or camcorders via an i.LINK (file access mode) connection – just as a PC reads files on an external drive.
Seamless Integration into Current VTR-Based Systems
In order to achieve seamless integration into current tape based systems, a great deal of thought has been put into the development of Sony XDCAM products. A range of conventional AV interfaces including SDI, analogue video and analogue/digital audio I/Os allows easy connectivity to current equipment, including a wide variety of VTRs, linear and non-linear editors, and audio mixers.
