A Professional video camera (often called a Television camera even though the use has spread) is a high-end device for recording electronic moving images (as opposed to a movie camera, that records the images on film). Originally developed for use in television studios, they are now commonly used for corporate and educational videos, music videos, direct-to-video movies, etc. ImageMetadata File history File links Download high resolution version (1160x662, 301 KB) Sony camera head w/Betacam SP dock recorder. ...

There are two types of professional video cameras: High end portable, recording cameras (essentially, high-end camcorders) used for ENG and EFP image acquisition, and studio cameras which lack the recording capability of a camcorder, and are often fixed on studio pedestals. Portable professional cameras are generally much larger than consumer cameras and are designed to be carried on the shoulder. Before the camcorder. ...

Technology

It is common for professional cameras to split the incoming light into the three primary colors that humans are able to see, feeding each color into a separate pickup tube (in older cameras) or charge-coupled device (CCD). Some high-end consumer cameras also do this, producing a higher-quality image than is normally possible with just a single video pickup. A primary color or colour is a color that cannot be created by mixing other colors in the gamut of a given color space. ... Trinomial name Homo sapiens sapiens Linnaeus, 1758 Humans, or human beings, are bipedal apes belonging to the mammalian species Homo sapiens (Latin for wise man or knowing man) under the family Hominidae (known as the great apes). ... In older video cameras, prior to the 1990s, a video camera tube or pickup tube was used instead of a charge-coupled device (CCD). ... A specially developed CCD used for ultraviolet imaging in a wire bonded package. ...


Studio cameras

Most studio cameras stand on the floor, usually with pneumatic or hydraulic mechanisms to adjust the height, and are usually on wheels. Any video camera when used along with other video cameras in a studio setup is controlled by a device known as CCU (camera control unit), to which they are connected via a Triax or Multicore cable. The camera control unit along with other equipments is installed in the production control room often known as Gallery of the television studio. When used outside a studio, they are often on tracks. Initial models used analog technology, but digital models are becoming more common. Some studio cameras are light and small enough to be taken off the pedestal and used on a cameraman's shoulder, but they still have no recorder of their own and are cable-bound.

Triaxial Cable is a type of electrical cable similar to coaxial cable, but with the addition of an extra layer of insulation and a second conducting sheath. ... A multicore cable or snake (in the audio recording and entertainment fields) is a compact cable, typically about the diameter of a coin, which contains typically 16-24 individual microphone cables all housed by one common outer rubber jacket. ... A television studio is an installation in which television or video productions take place, either for live television, for recording live on tape, or for the acquisition raw footage for postproduction. ... An analog or analogue signal is any continuously variable signal. ... A digital system is one that uses discrete values (often electrical voltages), especially those representable as binary numbers, or non-numeric symbols such as letters or icons, for input, processing, transmission, storage, or display, rather than a continuous spectrum of values (ie, as in an analog system). ...


ENG cameras

Often used in independent films, ENG video cameras are similar to consumer camcorders, and indeed the dividing line between them is somewhat blurry, but a few differences are generally notable: An independent film, or indie film, is a film initially produced without financing or distribution from a major movie studio. ...

  • They are bigger, and usually have a shoulder stock for stabilizing on the cameraman's shoulder
  • They use 3 CCDs instead of one (as is common in digital still cameras and consumer equipment), one for each primary color
  • They have removable/swappable lenses
  • All settings like white balance, focus, and iris can be manually adjusted, and automatics can be completely disabled
  • If possible, these functions will be even adjustable mechanically (especially focus and iris), not by passing signals to an actuator or digitally dampening the video signal.
  • They will have professional connectors - BNC for video and XLR for audio
  • A complete timecode section will be available, and multiple cameras can be timecode-synchronized with a cable
  • "Bars and tone" will be available in-camera (the bars are SMPTE (Society of Motion Picture and Television Engineers) Bars similar to those seen on television when a station goes off the air, the tone is a test audio tone)
  • Finally, they will use a professional medium like some variant of Betacam or DVCPRO, though some professional DV cameras are available, Canon's XL1/XL2 and Sony's VX2100 cameras being examples. The XL1/2 and Sony VX2100 and cameras similar to them are not considered professional cameras, but fall into the "pro-sumer" line.

Dock cameras

Some manufacturers build camera heads, which only contain the optical array, the CCD sensors and the video coder, and can be used with a studio adaptor for connection to a CCU or various dock recorders for direct recording in the preferred format, making them very versatile. However, this versatility leads to greater size and weight, and dock cameras have become rare in recent years. They are, however, still favored for electronic field production and low-budget studio use, because they tend to be smaller, lighter, and less expensive than most studio cameras. Electronic field production (EFP) is a television industry term referring to television production which takes place outside of a formal studio, in a practical location or special venue. ...

At the top is the 3CCD, which is indispensable for the professional video cameras because of its outstanding reproductivity in color, detail and gradation.
The MPEG2 is the same codec system that DVD video camera encodes the data, assuring 50 fps at the same rate as TV broadcasts in all XP/SP/LP recording modes to make the motion smooth and natural-looking.
The pictures taken by the video camera have a lot of movement with panning, tilting or zooming and noises are often generated because the movements are too fast for the MPEG2 codec system to catch up with.
