Know About Digital Video Tapes.
Digital video is a format which was inducted in the year 1994. It is backed by manufacturers such as Sony, Philips, Thomson, Hitachi, Panasonic and other such companies. Ever since, it has become a standard for home and semi-professional video production, especially in its smaller tape form factor called MiniDV. It is also used for professional purposes sometimes, for example, film making and electronic news gathering also called ENG. The digital video specification covers both the codec form and the digital video tapes format as well. Features of the digital video tapes include intraframe compression and uncomplicated editing, a standard interface for transference to non-linear editing systems, and good quality video viewing, especially when compared to earlier consumer analog formats. Thanks to digital video tapes, filmmakers can now produce movies inexpensively, thus it is strongly associated with independent filmmaking and citizen journalism.
Digital video tapes can also be used to record a high definition format or a HDV in cameras designed in this codec. MiniDV tapes are the smallest of the video recording formats. They store and maintain crystal clear images because of the nature of a digital format. Editing enthusiasts benefit extensively through the MiniDV as well, since copying between two units is appropriately completed without any loss in the quality of the video. Thus, the edited or copied form of the video looks and sounds every bit as good as the original footage. Mini DV tapes are available in 30, 60, 63 and 80 minutes in lengths. Mini DV tapes can also be transferred to VHS so as to be able to watch the footage on a normal VHS VCR. As the first digital video recording system for consumers, Mini DV represents a marked advance in the quality of the video produced, when compared to the conventional analog recording systems.
Digital video formats offer more precise image details and color accuracy than was previously possible with analog camcorders. The advanced quality of the digital video results from:
* Higher resolution; up to 500 lines of horizontal resolution provide sharper picture detail, by recording more color information. * Time base correction, which stabilizes the picture, practically eradicating video jitters. * Component color sampling, which preserves three times more color information, when compared to the analog video for brighter and more exact colors. * Error correction, which fills in missing video data, making available seamless and professional looking videos. Digital video tapes, which have in-built IC memory chips, offer the consumer the opportunity to build a Table of Contents of the tape, which can be accessed automatically to locate a particular desired recording date, index point or even add titles to the memory that can be switched on and off during playback. The IC memory chips in the Mini DV tapes does not effect the way in which the picture is recorded and is not needed to get any extra results.
