Digital video is just a sort of video recording system that actually works by making use of a digital, as opposed to analog, representation associated with the video sign. This term that is generic to not be confused with the name DV, which is really a certain kind of digital video. Digital video is usually recorded on tape, then distributed on optical discs, usually DVDs. There are exceptions, such as camcorders that record right to DVDs, Digital8 camcorders which encode digital video on old-fashioned analog tapes, as well as the latest JVC Everio G camcorders which record video that is digital hard disks.

The terms "camera", "video camera", and "camcorder" are used interchangeably in this essay.

Introduction
Video digital cameras may be found in two different image capture platforms: interlaced and scan that is progressive. Interlaced cameras record the image in alternating sets of lines: the lines that are odd-numbered scanned, then the even-numbered lines are scanned, then the odd-numbered lines are scanned once more, and so on. One set of odd and sometimes even lines is referred to as a "field", and a pairing that is consecutive of areas of reverse parity is known as a framework.

A scanning that is progressive video camera records each frame as distinct, with both fields being identical. Therefore, interlaced video captures twice as numerous fields per 2nd as progressive video does when both operate at the same number of frames per second. This will be one of the reasons video includes a "hyper-real" look, since it attracts a different image 60 times per 2nd, instead of film, which records 24 or 25 progressive frames per second.
