Compatibility of the
DVCAM/DV formats
The DVCAM format was developed as a
more reliable and higher-end format than
the consumer DV format. Explained here
are the differences, compatibility, and
limitations on editing for the DVCAM and
DV formats.

* There are 2 modes for audio recording, lock
mode and unlock mode. In lock mode, the
sampling frequencies of audio and video are
synchronized. In unlock mode, which the
consumer DV format adopts, the 2 sampling
frequencies are independent. Therefore,
lock mode is more effective than unlock
mode in digital processing and smooth
transition during audio editing.

• This camcorder complies with the DVCAM
format.
Though mini DV cassettes can be used for
recording, we recommend you use mini
DVCAM cassettes to get the most out of the
high reliability of the DVCAM format.
• The recording time of mini DV cassettes is 1/3
shorter than that indicated on mini DV cassettes
when recorded in the DVCAM format.
