Features Compact size and light weight This is a 4U digital VTR. Using the rack-mounting adapters (AJ-MA75P: optional accessory), it can also be easily housed in a 19-inch rack. Up to 126 minutes of recording Using the DVCPRO HD-LP recording system, up to 126 minutes of material can be recorded on the 1/4-inch XLsize cassette tape. High picture quality The VTR's high picture quality is achieved by 4:2:2 HD component signal recording using a recording rate (100 Mbps) which is 4 times higher than that of the existing DVCPRO format. 1080i/720p, 59.94 Hz/60 Hz/50 Hz signal switching By making menu selections, the signals of the respective formats can be recorded and played back. No guarantees are made for the recording in 1080-60 Hz. Frame rate conversion function By making menu selections, the VTR can output signals after converting them to the 1080/24PsF format when it plays back a tape recorded by a variable frame rate camera at a frame rate of 24fps. When playing back a tape recorded at a frame rate of 25 fps, the tape's signals can be converted to the 1080/25 PsF or 576i format and output. When playing back a tape recorded at a frame rate of 50 fps, the tape signals can be converted to the 1080/50i or 576i format and output. z Use tapes that are shot with a variable frame rate camera. z Do not use dubbed or edited tapes. The tape control information may be lost, making it impossible to convert the signals for playback. Gamma correction of cinema for film This feature corrects the image from a variable frame rate camera in cinema gamma mode for film to an image with film quality. Digital slow motion/dial jog Panasonic's unique digital slow motion technology enables clear playback (of tapes recorded using the DVCPRO HD-LP system) at speeds ranging from j1k to i2k. Some noise may occur during slow playback (using an external controller) at speeds of almost exactly j1k or i2k. Search speed Search speed enables tapes (recorded using the DVCPRO HD-LP system) to be played back with color images at speeds of up to 100 times in the forward or reverse direction. Time codes This VTR comes with a built-in time code generator (TCG)/time code reader (TCR). In addition to the internal time code, an external time code can also be input and recorded as the LTC on the VTR. UMID information recording and playback This unit supports the recording/playback of UMID (Unique Material Identifier) information in the SMPTE 330M standard. UMID information can be confirmed with the diagnostic menu. VTRs that do not support the recording/playback of UMID information will not playback UMID information correctly. In addition, when VTRs that do not support recording/playback of UMID information are connected to this unit, UMID information will not be recorded correctly. VANC data recording/playback VANC data packets that added to the Y stream of HD SDI can be recorded with the video signal. In addition, VANC data packets can be played back with the Y stream of HD SDI. SDI interface The VTR comes with an HD/SD serial digital interface as a standard accessory. Playback compatibility with DVCPRO systems Besides DVCPRO HD-LP recording and playback, the VTR can also play back tapes which have been recorded using the existing DVCPRO HD, DVCPRO50 and DVCPRO systems. Consumer-use DV tapes (SP) and DVCAM tapes can also be played back on this VTR. 8
