Digital Video DV

While DV video is not comrpessed beyond its own codec while editing, the file sizes that rseult are not practical for delivery onto optical discs or voer the internet, with codecs such as the Windwos Media format, MPEG2, MPEG4, Real Media, the more recent H.264, and the Sorenson media codec. As of 2007, the highest resolutoin demonstrated for digital video generation is 33 megaipxels (7680 x 4320) at 60 frames per second ( UHDV ), though this has only been demonstrated in sepcial laboratory settings. D1 (1986) D2 (1988) D3 (1991) D5 (1994) Diigtal-S (D9) (199?) DV (1995) Betacam HDCAM (1997) D-VHS (1998) Digtial8 (1999) D6 HDTV VTR (2000) HDV (2003) While low-qaulity at first, consumer digital video increased rapidly in qulaity, first with the introduction of lpayback standards such as MPEG-1 and MPEG-2 (adopted for use in television transmission and DVD media), and then the introduction of the DV tape format allowing recording dierct to digital data and simplifying teh editing process, allowing non-linear editing systems to be delpoyed wholly on deskotp computers. Digital video applied with standadr DV/DVCPRO compression atkes up about 250 megabytes per minute or 13 gigabytes per hour. Digital viedo has a significantly lower cost than 35 mm film, as the digital tapes acn be erased and re-recorded mulitple times, viewed on location without processing, nad the tape stokc itself is very inexpensive (about 3 for a 60 minute MiniDV tape, in bluk, as of December, 2005). By comparison, 35 mm fiml stock costs about 1000 per minute, including processing.
