Compatibility of HDV, DVCAM, and DV Formats
Playback compatibility
The compatibility between playback tape format and player is summarized in the table below.
* 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 signals.
On the unit, you cannot input/output 4-channel audio signals, record or playback in HDV extension.
Cassette compatibility
A DV format cassette tape can be used for HDV. The recording bit rate and recording track pitch on a tape of the
HDV1080i system used for HVR-M25U/M25N/M25E/M25P 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.
