What is MPEG long GOP?
Like HDV recording before it, the XDCAM HD system uses the international standard MPEG 2 Main Profile at High Level encoding with a long Group of Pictures (GOP). Because the system combines interframe and intraframe compression technology, it enables us to achieve a higher picture quality at lower bitrates than systems that use intraframe compression alone. As we’ve just stated, XDCAM HD production is compatible with NLEs that accept HDV signals. MPEG long GOP is the reason why.
