The image sensor is new. The main video processing is new – accomplished by deploying two powerful Digic DV5 processors compared to the single Digic DV3 processor of the C300. And finally, the codec that powers the on-board recording is also new – intheformofthe formidable new XF-AVC [6]that replaces the more modest MPEG-2 codec of the C300.
The broad experiences gained with the first generation C300 emphasized that these camcorders are often subject to severe environmental conditions. The C300 was unusual in its quite low overall power consumption – totaling less than 5 watts during recording – and its cooling system proved adequate. The C300 Mark II consumes more than twice the power of the C300 (because of more powerful video processing and greatly extended on-board recording capabilities), and accordingly, a more sophisticated cooling system has been incorporated.

The original EOS C300 represented Canon’s definitive entry into the digital cinematography marketplace. While largely television-centric and comparatively modest in its recording capabilities it quickly established a worldwide reputation for excellent image quality, ergonomics that favored handheld shooting, unusually high sensitivity, and very low power consumption.
