D5 is an professional digital video format introduced by Panasonic in 1994. Like Sony's D1, it is an uncompressed digital component system, but uses the same half-inch tapes as Panasonic's digital composite D3 format.

HD D5 uses standard D5 video tape cassettes to record HD material, using a intra-frame compression with a 4:1 ratio. HD D5 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 uncompressed audio channels sampled at 40 kHz, 20 bits per sample, are also supported.

HD material also is often captured for post production of film projects, especially on lower budget films, from the Super 16mm film format (15:9 aspect ratio crops well to 16:9 HDTV widescreen ratio) whereby the HD D5 scanning equipment is cheaper by the hour than a full resolution 2K film scan. Most importantly the 1920x1080 resolution at 24 progressive frames per second, with MPEG-2 or MPEG-4 compression, can be edited on high-end desktop computers in 2004.
