Panasonic DVCPROHD Recording Information
Also, there are two different tape recording types within DVCPROHD: the older DVCPROHD 18 micron track recordings, and the newer DVCPROHD 9 micron track recordings. These two recording types are not physically compatible, although the newer 9 micron VTRs can play back the older 18 micron tapes. The large AJ-HP126EX tapes can hold up to 126 minutes of DVCPROHD (these tapes fit only in the AJ-HD1700 and AJ-HD1800 VTRs). The AJ-HD1200A was designed to be limited to a maximum of only 92 minutes using the AJ-HP92EL tapes, but these tapes are no longer manufactured. The largest tape load for the AJ-HD1200A is the AJ-HP64EL tape, which runs about 64 minutes in DVCPROHD.
The total number of frames per second as stored on DVCPROHD on tape are limited to 59.94/60 (720p or 1080i depending). When 23.98 frames per second camera choice is made on a Varicam, the tape fills up using a certain pattern and number of redundant frames. The basic utility of the AJ-HD1200A with IEEE Option/AJ-HD1400/AJ-HD1800 in post editorial is simply the 100Mb/s IEEE option to "avoid" unnecessary or transitory compress/decompress cycles, and to transfer out of the VTR to an appropriate NLE system such as Final Cut Pro 4.5HD (or higher) in a native form, where the settings in the NLE allow the redundant frames to be identified and thrown away upon capture to save storage space. The AJ-HD1200A did not support VANC. The AJ-HD1400 and AJ-HD1800 do support VANC.
The specifications and procedures discussed in this section are subject to generalization, and may include significant errors and omissions. This information is subject to change without notice. Because individual systems and their performance, including valid and required settings, may vary greatly, they are not detailed on this web site. You should consult with both Panasonic and VTP on a case by case basis to qualify any specific equipment performance or to validate your particular configuration or application.
