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.

Compatibility of the
DVCAM and 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.
Differences between 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.
Mini DVCAM and mini DV cassettes
The recording format of the picture is defined
according to the recorder’s format as described
below.
•
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.
Compatibility on playback
Compatibility on editing using DV jacks
When this camcorder is connected to other
digital video equipment using an i.LINK cable,
the recording format of edited tapes is defined
according to the source tape and the recorder’s
format as described below. Playback or editing
using the edited tape may be limited depending
on dubbing operation. Start dubbing after
reading “Limitations on editing” (p. 117).
