Definição do conceito
[ENG] DVCPRO50 | DVCPRO50 was introduced by Panasonic in 1997 for high-value electronic news gathering and digital cinema, and is often described as two DV codecs working in parallel. | The DVCPRO50 doubles the coded video data rate to 50 Mbit/s. This has the effect of cutting total record time of any given storage medium in half. Chroma resolution is improved by using 4:2:2 chroma subsampling. | DVCPRO Progressive | DVCPRO Progressive was introduced by Panasonic for news gathering, sports journalism and digital cinema. It offered 480 or 576 lines of progressive scan recording with 4:2:0 chroma subsampling and four 16-bit 48 kHz PCM audio channels. Like HDV-SD, it was meant as an intermediate format during the transition time from standard definition to high definition video. | The format offered six modes for recording and playback: 16:9 progressive (50 Mbit/s), 4:3 progressive (50 Mbit/s), 16:9 interlaced (50 Mbit/s), 4:3 interlaced (50 Mbit/s), 16:9 interlaced (25 Mbit/s), 4:3 interlaced (25 Mbit/s). | The format has been superseded by DVCPRO HD. | SOURCE : DVCPRO. in : Wikipedia.

[ENG] DVCPRO50 | DVCPRO50 (1997 – early 2010s) | DVCPRO50 was a higher-bandwidth version of Panasonic’s DVCPRO professional video tape format, and was introduced in 1997. It used two DV codecs in parallel, doubling the data rate over the original DVCPRO to 50 Mbps.| DVCPRO50 equipment could use DVCPRO tapes, but the tape was run at twice the speed so capacity was halved. DVCPRO, DVCPRO50 and DVCPROHD tape uses the same ¼-inch metal particle tape formulation, the only difference being the lid colour with tapes made for DVCPRO50 having a blue lid. | 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.
