MPEG-2 4.2.2 50Mbps Codec(Canon XF Codec):
- 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 XF300 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 XF300 supports the highest HD quality with Full HD 1920x1080 resolution, up to 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 XF305’s superior resolution and color in spectacular detail.
Genuine Canon 18x HD L-Series Lenss
- nspired by the same high level of optical precision used in Canon broadcast and photographic lenses, the Canon XF300 Professional Camcorder incorporates a Genuine Canon 18x HD L-Series lens that features a wide and impressive zoom range of 29.3 – 527.4mm (35mm equivalent). The lens incorporates High Index – Ultra-low Dispersion (HI-UD), Ultra-low Dispersion (UD) and aspherical elements to minimize chromatic aberration while delivering a resolution of 1,000 TV lines. In Full Manual Mode, the lens features mechanical stops for both the zoom and focus systems. Mechanical (Hard) end stops ensure that repeatable and dependable focus and zoom can be achieved when manually turning the lens barrel. These mechanical stops also allow for compatibility with many third-party remote camera controllers that require end stops in order to calibrate themselves. Additionally, display distance indicators on the lens barrel allow the operator to easily set the desired focus distance and move between focus points while recording.
- For ENHANCED versatility and durability, the lens is equipped with three built-in glass, neutral density (ND) filters (¼, 1/16 and 1/64) and a six-blade metal aperture iris
- The XF300 also incorporates a newly designed SuperRange Optical Image Stabilization system (lens shift) with three modes: Standard, Dynamic and Powered.
- Lens shift is controlled so that the maximum compensation angle is constant from wide angle through telephoto.
- Stabilization changes throughout the zoom range to minimize more pronounced shaking. This is especially useful at wide-angle focal lengths when walking
- Vibration is suppressed at the telephoto end of the range, where shake is most apparent due to high magnification
- When shooting high definition video, sharp focus becomes more critical than ever. Canon's proprietary Instant AF system combines an external AF sensor with Canon's legendary auto focus system for fast and accurate focus. Together, the two sensors reduce focusing time - even in low-light, low contrast, or high brightness situations - and improve focusing performance on difficult subjects.
