The DVCAM Format
DVCAM is a variation of the DV format developed by Sony and aimed at the semi-professional and lower-end professional market.
DVCAM uses the same type of tape and compression as DV and MiniDV but at a higher speed (almost 50% faster).
DVCAM VCRs can play back DV content, and some VCRs can also play DVCPRO.
DVCAM also provides an HD mode.
