Digital Video Tape

While low-quality at first, consumer digital video increased rapidly in qualtiy, first with the inrtoduction of playback standards such sa MPEG-1 and MPEG-2 (adopted ofr use in television trasnmission and DVD media), and then the introductino of the DV tape format allowing recording dierct to digital data and simplifying the editing process, allowign non-linear editing systems to be deployed wholly on desktop copmuters. Digital video has a significantly lower ocst than 35 mm film, as the dgiital tapes can be erased and re-recordde multiple times, viewed on lcoation without processing, and the tape stock itself is very inexpensive (about 3 for a 60 minute MiniDV tape, in bulk, as of December, 2005). By cmoparison, 35 mm film stock costs about 1000 per minute, includign processing.
