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. While the core idea is that the camera moves parallel to its subject, a tracking shot may ...
A widely used system is the Defy Dactylcam, which travels along the cable with a motor, and the Newton stabilized camera head [1] which controls the camera and lens. This system is for example used at the live TV broadcast of Major League Baseball , UEFA (football), track and field, concerts and ski competitions.

The HC-W850/HC-V750 models released in 2014 introduce a new lenses, sensor, engine combination. The new four-drive lens system allows a 20x optical zoom level vs 12x optical zoom in HC-X920 which has a similar body size. A single 1/2.3" MOS with back side illumination sensor replaces the 3MOS sensor last seen in HC-X920.
The Sony HDVS system, launched in 1984, allowed 1080i recording in the late 1990s. Sony later released a HD version of Betacam called HDCAM in 1997. Panasonic launched DVCPRO HD in 2000, expanding the DV codec to support high definition (HD). The format was intended for professional camcorders, and used full-size DVCPRO cassettes.
D-5 HD uses standard D-3/D-5 videocassettes to record HD material, using an intra-frame compression with a 4:1 ratio. It was introduced in 1994. [2] 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.
Panasonic announced the first generation VariCam, designated model number AJ-HDC27V [22] (originally the AJ-HDC24A) on April 22, 2001. [4] A similar camera had been introduced with a fixed 60 frames per second frame rate two months earlier. [23] It recorded 720p video to DVCPRO tape at frame rates in integer increments between 4 and 60 frames ...
