Videotape
DVCPRO
Panasonic specifically created the DVCPRO family for ENG use with better linear editing capabilities and robustness. It has an even greater track width of 18 micrometres and uses another tape type (Metal Particle instead of Metal Evaporated). Additionally, the tape has a longitudinal analog audio cue track. Audio is only available in the 16 bit/48 kHz variant, there is no EP mode, and DVCPRO always uses 4:1:1 color sub sampling (even in PAL mode). Apart from that, standard DVCPRO is otherwise identical to DV at a bit stream level. However, unlike Sony, Panasonic chose to promote its DV variant for professional high-end applications. Also known as DVCPRO 25
DVCPRO50 is often described as two DV-codecs in parallel. The DVCPRO50 standard doubles the coded video bit rate from 25 Mbit/s to 50 Mbit/s, and improves color-sampling resolution by using a 4:2:2 structure. DVCPRO50 was created for high-value ENG compatibility. The higher data rate cuts recording-time in half (compared to DVCPRO25), but the resulting picture-quality is reputed to rival Digital Betacam, a more expensive studio format.
DVCPRO HD, also known as DVCPRO100, uses four parallel codecs and a coded video bit rate of 100 Mbit/s. Despite HD in its name, DVCPROHD downsamples native 720p/1080i signals to a lower resolution. 720p is downsampled from 1280x720 to 960x720, and 1080i is downsampled from 1920x1080 to 1280x1080 for 59.94i and 1440x1080 for 50i. Compression ratio is approximately 7:1. To maintain compatibility with HDSDI, DVCPRO100 equipment internally downsamples video during recording, and subsequently upsamples video during playback. A camcorder using as special variable-frame rate (from 4 to 60 frame/s) variant of DVCPRO HD called VariCam is also available. All these variants are backward compatible but not forward compatible.
