HD 1080 Recording at Selectable Frame & Bit Rates
XDCAM HD products can record video signals in 1080/59.94i, 50i, 29.97P, 25P and native 23.98P - using a "MPEG HD" codec with industry standard MPEG-2 MP@HL compression. The user can also select the following bit rates; 35, 25 or 18Mb/s depending on picture quality and recording length requirements. When using the new 50GB Dual Layer Professional Disc the highest bit rate of 35Mb/s results in a recording time of more than 145 minutes, while choosing 18Mb/s provides a recording time of more than 248 minutes - the longest recording time offered by any current HD camcorder. MPEG HD images are recorded at 1440x1080 pixels with 4:2:0 sampling.
