The Sony PMW-EX3 is a flash-memory based high definition camcorder capable of a variety of frame rates and resolutions using Sony's new XDCAM-EX intraframe codec. A "big-brother" to the PMW-EX1, the PMW-EX3 ups the ante by providing an interchangeable lens mount. The mount allows users to put a variety of professional lenses on the camera, including 1/2" and 2/3" bayonet mounts (with optional adapter).
Enhancing both usability and workflow efficiency, the PMW-EX3 has an extensive set of features that push the boundaries of traditional handheld cameras, including a continuous record time of up to 140 minutes! Whether shooting in 720p, 1080i, or 1080p modes, the PMW-EX3 has it all covered. Its bevy of output settings lets users take advantage of fast and slow motion, as well as popular frame rates such as the "film-like" 24p mode.
XDCAM EX is a variant of Sony's popular XDCAM HD codec, which has become a benchmark for affordable non-linear professional acquisition. Through the use of flash-based memory, the PMW-EX3 can take advantage of variable bit rate (VBR) recording. VBR technology intelligently employs less or more image compression to different portions of the footage dependent on which areas need additional bandwidth. The end result is higher quality video with a reduced amount of compression artifacts when compared to more antiquated constant bit rate (CBR) methods.
