Panasonic Expands DVCPRO HD Recording Time
Panasonic has launched the AJ-HD1700 DVCPRO HD VTR offering extended recording times, improved slow motion and lower tape costs for HD program production, distribution and archiving.
Targeting mobile units, production studios or editing suites, the AJ-HD1700 VTR can record for up to 126 minutes in 1080/60i, 1080/50i or 720/60p high-definition formats on a single AJ-HP126EX cassette. The low tape cost of operation is achieved by using 9-micron track-width recording, which delivers twice the recording density of existing DVCPRO HD recorders plus editing reliability thanks to editing-point guard tracks, a double-head playback system, new metal-in-gap (MIG) heads and powerful error-correction circuitry.
The AJ-HD1700 can also convert 24fps footage acquired by Panasonic's AJ-HDC27 VariCam HD Cinema camera to 1080/24p, allowing the VTR to act as a source deck in a 1080/24p-based linear or nonlinear editing bay. Source VTR operation in 1080/25p is also supported for PAL television applications.
The AJ-HD1700 offers full playback compatibility with all existing quarter-inch DV-based compression formats including DV, DVCAM, DVCPRO, DVCPRO50, DVCPROP as well as DVCPRO HD. The VTR is also equipped with a built-in format up/downconverter for downconverting 1080i or 720p HD video to 480i or 480p, and upconverting pre-recorded DV, DVCAM, DVCPRO, DVCPRO50, DVCPROP tapes to 1080i or 720p HD.
An optional AJ-UC1700G board allows users to upconvert SD material to HD and to record to HD instantaneously, providing broadcasters with a drop-in replacement for an existing SD VTR as well as a practical multiformat HDTV recorder.
