* The unit can play back for HDV720/30p format, but you cannot output the video signals from HDV/DV jack.
The unit cannot play back other than HDV1080/60i, HDV1080/50i, such as HDV1080/30F, HDV1080/25F, HDV1080/
24F, HDV720/25p, and HDV720/24p format. The unit cannot input/output, record, or play back extended HDV format
signals with 4-channel audio mode.
Cassette compatibility
A tape with DV or miniDV mark can be used for HDV. The recording bit rate and recording track pitch on a tape
of the HDV1080i system used for the unit are about 25 Mbps and 10 µm, respectively. The specifications are the
same as that of home use DV (SP) tapes. The recording time on an HDV tape is also the same as that of DV (SP).
The track pitch of DVCAM is 15 µm, which is 1.5 times of HDV/DV (SP). Therefore, the recording time using
DVCAM recording on a same tape will be two-thirds of the time available when HDV/DV (SP) recording is used.

recorded in SP mode is
