Easy Migration from SD to HD – DVCAM Recording and Up/Down Conversion
The XDCAM HD camcorder provides the powerful capability to record in DVCAM format with NTSC/PAL and 16:9/4:3 switchable modes, as well as the MPEG HD format. What’s more, both camcorder and decks incorporate a down-conversion capability that allows material recorded in the MPEG HD format to be converted to DV signals and output via the i.LINKTM* port, enabling users to edit the material using compatible DV-based nonlinear editors. The PDW-F70 recording deck also has the up-conversion capability to allow material recorded in the DVCAM format to be converted to HD signals and output via its HD-SDI or HD analog component connector. These capabilities allow users to easily and flexibly migrate to HD-based operations at their own pace.
File-based Disc Recording
As a recording medium, the XDCAM HD products use a nonlinear optical disc, the PFD23 Professional Disc, which Sony has developed specifically for professional recording applications. Recordings are made on a file basis, allowing easy integration into other IT-based equipment such as PCs and nonlinear editors. The recorded files on the disc can be directly accessed by a compatible PC connected via the i.LINK (File Access Mode) interface, and furthermore can even be sent through a standard Ethernet network. This file-based operation enables new networkbased workflows that have never been available for HD-based production. The XDCAM HD system also features the Scene Selection function that allows simple cuts-only editing to be instantly performed within the camcorder or decks.
Outstanding Operational Convenience by Disc Recording
Because the XDCAM system records video and audio as files on a disc, the XDCAM HD products offer a range of tremendous benefits, especially instant random access to footage. Another significant advantage of disc recording is that new footage is always recorded onto an empty area of the disc, eliminating the worry of accidentally overwriting valuable existing footage.
Powerful Proxy Recording – Enhancing Your Workflows
The XDCAM HD products record low-resolution AV data concurrently with its high-resolution data on the same disc. This low-resolution data version – called “Proxy Data” – is much smaller in size than high-resolution data (1.5 Mb/s for video and 0.5 Mb/s for audio), and its format is identical to that of the current XDCAM products. The data can be conveniently used for a variety of applications, such as immediate logging on location, off-line editing, daily rushes of shooting on location, client approvals and more. Proxy Data can be browsed and edited on a standard PC using the PDZ-1 Proxy Browsing software supplied with all XDCAM HD products or other compatible editing software offered by other industry-leading manufacturers.
High Level of Reliability
The XDCAM HD products adopt the same platform as the XDCAM SD products that are widely in use around the world today. Having the advantage of no mechanical contact between recording media and recording heads of tape based camcorders and decks, a high level of durability and long media life have been achieved. XDCAM HD products also offer the same high resistance to shock and vibrations provided by current XDCAM products.
