[ENG] DVCPRO | DVCPRO, also known as DVCPRO25, is a variation of DV developed by Panasonic and introduced in 1995 for use in electronic news gathering (ENG) equipment. | Unlike baseline DV, DVCPRO uses locked audio, meaning the audio sample clock runs in sync with the video sample clock, and 4:1:1 chroma subsampling for both 50 Hz and 60 Hz variants to decrease generation losses. Audio is available in 16-bit/48 kHz precision. | When recorded to tape, DVCPRO uses wider track pitch - 18 ?m vs. 10 ?m of baseline DV, which reduces the chance of dropout errors during recording. Two extra longitudinal tracks provide support for audio cue and for timecode control. Tape is transported 80% faster compared to baseline DV, resulting in shorter recording time. Long Play mode is not available. | SOURCE : DVCPRO. in : Wikipedia. Available at : https://en.wikipedia.org/wiki/DV#DVCPRO Accessed : 20 nov. 2022

[ENG] DVCPRO | DVCPRO (1995 – early 2010s) | DVCPRO (also known as DVCPRO25 or D-7) is a variation of the DV format, and was introduced by Panasonic in 1995 for professional and broadcast use. | In common with all DV formats, DVCPRO uses tape that is ¼-inch (6.35 mm) wide, but DVCPRO uses metal particle (MP) tape rather than metal evaporate. DVCPRO also adds an analogue audio cue track and a control track to make editing easier. | DVCPRO50 was introduced in 1997 and used two DV codecs in parallel, doubling the data rate over the original DVCPRO to 50 Mbps. DVCPRO50 decks can use DVCPRO tapes, but the tape is run at twice the speed so capacity is halved. | In 2000, Panasonic launched DVCPRO HD for high-definition recording. This had a data rate of 100 Mbps and competed with Sony’s HDCAM. | Panasonic stopped selling equipment using video tape around 2013. | SOURCE : MUSEUM OF OBSOLETE MEDIA. Data Base.

[ENG] DVCPRO | DVCPRO | Synonyms ; D7 ; DVCPRO25 ; Digital Video (ambiguation) | Dates : 1995 – present | Common Size(s): Tape width: ¼" ; Cassette, medium: 3?" × 2 ½" × ½" / cassette, large: 4?" × 3" × ½" | Description : DVCPro is a magnetic tape-based digital video (DV) cassette format. The tape is composed of magnetic particles, a binder, and a polyester base. Large cassettes measure 4?" × 3" × ½", are for use in recording and editing decks, and have an available recording length of about 126 minutes. Medium cassettes measure 3?" × 2½" × ½", are for use in cameras, and have an available recording length of up to 66 minutes. Cassettes are generally dark gray in color with a yellow anti-static cover (Panasonic), black with a yellow anti-static cover (Maxell), or black with a red anti-static cover (Fuji). The DVCPro logo is usually in the upper right-hand corner, and the tape length is generally listed on the left-hand corner. Panasonic cassettes also designate large cassettes with the letter "L" after the tape length (i.e. 126L). | Composition : Polyester magnetic tape enclosed in a plastic cassette | SOURCE : PSAP - Preservation Self-Assessment Program.
