DVCPRO HD, also known as DVCPRO100 and D-12, is a [[high-definition video]] format that can be thought of as four DV codecs that work in parallel. Video data rate depends on frame rate and can be as low as 40&nbsp;Mbit/s for 24 frame/s mode and as high as 100&nbsp;Mbit/s for 50/60 frame/s modes. Like DVCPRO50, DVCPRO HD employs 4:2:2 color sampling. It was introduced in 2000.<ref>{{cite book |url=https://books.google.com/books?id=sQ1xAwAAQBAJ&dq=d5+hd&pg=PA150 |title=A Broadcast Engineering Tutorial for Non-Engineers |first1=Skip |last1=Pizzi |first2=Graham |last2=Jones |date=24 April 2014 |publisher=CRC Press |isbn=9781317906834 |via=Google Books }}</ref>

DVCPRO HD uses smaller raster size than broadcast high definition television: 960x720 pixels for 720p, 1280x1080 for 1080/59.94i and 1440x1080 for 1080/50i. Similar horizontal downsampling (using [[pixel aspect ratio|rectangular pixels]]) is used in many other magnetic tape-based HD formats such as [[HDCAM]]. To maintain compatibility with [[HD-SDI]], DVCPRO100 equipment upsamples video during playback.

Variable framerates (from 4 to 60 frame/s) are available on [[Varicam]] camcorders. DVCPRO HD equipment offers [[backward compatibility]] with older DV/DVCPRO formats.

When recorded to tape in standard-play mode, DVCPRO&nbsp;HD uses the same 18 μm track pitch as other DVCPRO flavors. A long play variant, DVCPRO&nbsp;HD-LP, doubles the recording density by using 9 μm track pitch.

DVCPRO&nbsp;HD is codified as SMPTE 370M; the DVCPRO&nbsp;HD tape format is SMPTE 371M, and the MXF Op-Atom format used for DVCPRO&nbsp;HD on P2 cards is SMPTE 390M.

While technically DVCPRO HD is a direct descendant of DV, it is used almost exclusively by professionals. Tape-based DVCPRO&nbsp;HD cameras exist only in shoulder mount variant.

A similar format, [[Digital-S]] (D-9 HD), was offered by JVC and used videocassettes with the same form-factor as [[VHS]].

The main competitor to DVCPRO HD was [[HDCAM]], offered by Sony. It uses a similar compression scheme but at higher bitrate.
