MPEG-2 compression is both highly reliable and versatile. Developed by the Moving Pictures Expert Group (MPEG), it is one of the most widely used compression schemes in the industry for camera acquisition, over the air broadcast, cable and satellite TV. Canon's adaptation of MPEG-2 for the XF100 Professional Camcorder, named the Canon XF Codec, ensures the widest compatibility with existing industry infrastructure and non-linear editing (NLE) systems. As well, by using an MXF file wrapper, video and audio can be wrapped in a single file along with important metadata.The XF100 supports the highest HD quality with Full HD 1920x1080 resolution, up to a 50Mbps bit rate and 4:2:2 color sampling.4:2:2 color sampling provides twice the color resolution of HDV and other codecs that use 4:2:0 color sampling. 4:2:2 provides ultra-fine transitions in tone and color and maintains the highest quality image for use in post production processes such as chroma keying, color grading, advanced compositing and effects.The codec’s 50Mbps constant bit rate provides the bandwidth needed to capture the XF100's superior resolution and color in spectacular detail.Unlike other camcorders which use proprietary memory systems, the XF100 Professional Camcorder records to cost-effective Compact Flash (CF) cards. The camcorder features two CF card slots and offers versatile recording functions including:Relay recordingWhen one CF card becomes full, the camcorder automatically switches video recording to the other CF card.Hot swappingMedia can be replaced without turning off the camcorder. And while recording, the other card can be removed without interruption.File copy and backupFiles may be copied from one card to the next – ideal for backing up when on location.
