Camcorder with XDCAM, XDCAM is an optical disk-based professional video system introduced by Sony. This camcorder features include tapeless optical disk recording of DVCAM, MPEG IMX and, in the XDCAM HD variant, HDV video data, as well as MXF metadata and a low resolution AV proxy stream, on a disc similar to a Blu-ray disc called the Professional Disc, which holds 23.3 GB of data in the PFD23 version and 50 GB in the PFD50 version. A XDCAM range includes cameras and decks which act as drop-in replacements for traditional VTRs allowing XDCAM discs to be used within a traditional tape-based workflow. These decks can also serve as random access computer drives for easy import of the video data files into non-linear editing (NLE) systems via IEEE 1394 and Ethernet. The XDCAM format uses multiple compression methods: MPEG-2 when recording in MPEG IMX, DV25 when recording in DVCAM and MPEG-4 when recording in a low resolution proxy stream.

The XDCAM HD variant of XDCAM records MPEG-2 long GOP at up to 35 Mbit/s (HQ mode). The DVCAM mode allows the user to record twice as much footage and maintains a large compatibility with a large amount of low end NLE's. MPEG IMX can record at a bitrate of 30, 40 or 50 Megabits per second, while DVCAM records at 25 Mbit/s. The low resolution proxy is recorded at 1.5 Mbit/s with 64 kbit/s for each audio channel. The CIF resolution is used for the proxy recordings. the next generation of XDCAM HD will utilize dual layer Professional Disk with capacity of 50 GB and an MPEG 4:2:2 HD codec with bitrate up to 50 Mbit/s. In addition, XDCAM, within Sony, means tapeless. In other word, XDCAM is not limited by optical disc. the Flash memory based camcorder, the PMW-EX1, employing three 1/2-inch "Exmor" CMOS sensors with over 2 million pixels was exhibited during the NAB (National Association of Broadcasters) 2007 show. It uses the MPEG-2 long GOP codec when recording to Express cards and a 4:2:2 color ratio can be achieved by using a HD-SDI out connection. finds XDCAM HD camcorders or camcorder professional from sony jvc canon and panasonic.
