Editing XDCAM (section)

==Compression methods==
The XDCAM format uses multiple [[video compression]] methods and [[media container]] formats.

Video is recorded with [[DV (video format)|DV]], [[MPEG-2 Part 2]] or [[MPEG-4]] compression schemes. DV is used for [[standard-definition video]], MPEG-2 is used both for standard and high definition video, while MPEG-4 is used for proxy video.

Audio is recorded in uncompressed [[Pulse-code modulation|PCM]] form for all formats except proxy video, which uses [[A-law algorithm|A-law]] compression.

Equipment that uses [[Professional Disc]] as well as XDCAM 4:2:2 on SxS cards as recording media employs [[Material Exchange Format|MXF]] container to store [[digital audio]]/[[digital video]] streams. [[Tapeless camcorder]]s that record onto [[Solid-state drive|solid-state memory]] cards, use MP4 container for high definition audio/video, and DV-AVI container for DV video. JVC camcorders that use XDCAM EX recording format, are also capable of recording into QuickTime container besides using MP4 container.
