Digital video is an electronic representation of moving visual images in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images in the form of analog signals. Digital video comprises a series of digital images displayed in rapid succession, usually at 24, 25, 30, or 60 frames per second ...
A Flip video camera, formerly manufactured by Cisco. A video camera is an optical instrument that captures videos, as opposed to a movie camera, which records images on film. Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in ...
Firmware in the camera, or a software in a raw converter program such as Adobe Camera Raw, interprets the raw data from the sensor to obtain a full-color image, because the RGB color model requires three intensity values for each pixel: one each for the red, green, and blue (other color models, when used, also require three or more values per ...

As technology improved, out-of-studio video recording was possible with compact video cameras and portable video recorders; a detachable recording unit could be carried to a shooting location. Although the camera itself was compact, the need for a separate recorder made on-location shooting a two-person job. [ 3 ]
The smaller sensors of Four Thirds System cameras have a crop factor of 2.0. While the crop factor of APS-C cameras effectively narrows the angle of view of long-focus (telephoto) lenses, making it easier to take close-up images of distant objects, wide-angle lenses suffer a reduction in their angle of view by the same factor.
Digital cinematography captures motion pictures digitally in a process analogous to digital photography.While there is a clear technical distinction that separates the images captured in digital cinematography from video, the term "digital cinematography" is usually applied only in cases where digital acquisition is substituted for film acquisition, such as when shooting a feature film.
