The DVCAM format was developed as a more reliable and higher end format than the consumer DV format. Here we explain the DVCAM and DV formats: the differences, compatibility and limitations on editing.

1)There are two 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 two sampling frequencies are independent. The lock mode maintains high compatibility with the higher formats and is more effective than unlock mode in digital processing and smooth transition during audio editing.
2)This unit cannot record in DV format with 16 bit – 32 kHz or 44.1 kHz.
DVCAM and DV cassettes
Both DVCAM and DV cassettes can be used on DVCAM or DV video equipment. The recording format is defined according to recorder format as described below.
