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 Mbit/s for 24 frame/s mode and as high as 100 Mbit/s for 50/60 frame/s modes. Like DVCPRO50, DVCPRO HD employs 4:2:2 color sampling.
A handheld or Steadicam mounted camera following a similar trajectory is called a tracking shot as well. In fact a tracking shot can use any manual or motorized conveyance, and may include careful planning for passing the camera between vehicles or modes.

A cable-suspended camera system is a system of cables above or along an area to be filmed or videoed, over or along which an attached camera head travels to achieve required camera angles.
Digital8 machines run tape at 29 mm per second, faster than baseline DV (19 mm/s) and comparable to professional DV formats like DVCAM (28 mm/s) and DVCPRO (34 mm/s). A 120-minute 8-mm cassette holds 106 m of tape and can store 60 minutes of digital video. A standard DVCPRO cassette holds 137 m of tape, good for 66 minutes of video.
The amazing shot in 'Atonement' covers the history of tracking shots and could be used as a base for further research for the article. —Erik (talk • contrib) - 18:37, 2 January 2008 (UTC) It's precisely that movie (which i saw last night) which brought me here. That 5½mn shot was phenomenal.
The camera uses a 1/2-inch colour Newvicon tube with a consumer-grade lens barrel giving a 6 times zoom with macro, normal focussing down to 4 feet (1.2 metres), and a minimum illumination of 10 lux. The microphone and folding viewfinder are physically built-in with no external cables, though headphones and an external microphone can used.
Developed to address the needs of the growing number of compressed video standards (DV, DVCPRO, BetaSX, MPEG2) it allows lossless transfer of data to other devices which have the same codec, for example DV to DV or SX to SX.
