D-5 HD

A high-density extension of the D-5 format; uses an intra-frame compression with a 4:1 ratio but the same tape.

D-5 HD uses standard D-5 videotape videotapes to record HD material, using an intra-frame compression with a 4:1 ratio. D-5 HD supports the 1080 and the 1035 interlaced line standards at both 60 Hz and 59.94 Hz field rates, all 720 progressive line standards, and the 1080 progressive line standard at 24, 25 and 30 frame rates. Four 48 kHz 24-bit PCM audio channels, or eight 48 kHz 20-bit channels, are also supported. D-5 runs at different data rates for different formats (taken from the hardware manual for the AJ-HD3700B:

  • 323 Mbit/s (1080/59.94i/8CH, 720/59.94p/8CH, 480/59.94i/8CH)
  • 319 Mbit/s (576/50i/8CH)
  • 300 Mbit/s (1080/59.94i/4CH, 720/59.94p/4CH, 480/59.94i/4CH)
  • 258 Mbit/s (1080/23.98p/8CH, 1080/24p/8CH)
  • 269 Mbit/s (1080/50i/8CH, 1080/25p/8CH, 576/50i/4CH)

HD material is often captured for the post-production of film projects, whereby the D-5 HD scanning equipment is cheaper by the hour than a full-resolution 2K film scan. Digital HD tape photographed movies such as Star Wars Episode II, Superman Returns, and Miami Vice often record to a 1080p format, however, these were mostly produced using the competing HDCAM and HDCAM SR formats from Sony. As of 2010, no D-5 HD camcorders have been offered for sale. Panasonic instead markets DVCPRO HD and P2 camcorders for field production of 720P or 1080i and 1080p images.

In 2007, Panasonic introduced an add-on box (AJ-HDP2000) that allows a standard D-5 VTR to encode 2K (2048 x 1080) resolution material with 4:4:4 color space onto D-5 tape using the industry-standard JPEG2000 wavelet-based compression.
