Sony's CineAlta 24P HD Cameras are a series of professional digital video cameras that offer many of the same features of a 35mm motion picture film camera. CineAlta is a brand name used by Sony to describe various products involved in content creation, production and exhibition process within digital cinema workflow. Now Sony's products branded by CineAlta include camera, camcorder, recorder, cinema server and projector. CineAlta cameras record onto HDCAM tapes, XDCAM Professional Discs or SxS flash memory cards. They have the ability to shoot at various frame rates including 24fps and have a resolution of up to 1920 by 1080 pixels. The camera can be used with a Miranda DVC 802 converter. This allows the camera to output SDI, DV and multiple HD outputs. The highly respected HDW-F900 camcorder has now been refined into the next-generation HDW-F900R, offering a variety of further enhanced functionalities. The HDW-F900R camcorder records images in accordance with the CIF (Common Image Format) standard, which specifies a sampling structure of 1920 x 1080 active pixels (horizontal x vertical). Plus, as well as recording at 24P, the HDW-F900R camcorder is switchable to record at 25P, 29.97P progressive scan, and also at 50 or 59.94 Hz interlaced scan. The HDWF900R also provides a comprehensive range of features for creative shooting such as enhanced gamma features and colorimetry controls. Plus, the design of the HDW-F900R is highly compact and lightweight, giving users higher levels of mobility and comfort when shooting. To further enhance the creative and operational versatility of the camcorder, a wide range of optional accessories are available. These include a picture cache board, a 2-3 Pull-down and down converter board, and a slow-shutter board. In combination with its renowned 24P capability and attractive cost efficiency, all of these great functionalities make the HDW-F900R the perfect solution for shooting television series , documentaries, commercials, as well as motion pictures. Unlike video formats, which are usually specified in terms of vertical resolution (e.g. 1080p, which is 1920x1080 pixels), digital cinema formats are usually specified in terms of horizontal resolution. As a shorthand, these resolutions are often given as multiples of a base size of 1024 pixels using a "K" suffix derived from the SI "kilo". So, for instance, a 2K image is 2048 pixels wide, and a 4K image is 4096 pixels wide. Vertical resolution varies with aspect ratio, so a 2K image with a 16:9 aspect ratio is 2048x1152 pixels, while a 2K image with a 2.35:1 aspect ratio would be 2048x872 pixels. All formats designed for digital cinematography are progressive scan, and capture usually occurs at the same 24 frame per second rate established as the standard for 35mm film.Despite the video format style notation, 24 frame per second 1080p can also be validly considered a digital cinema format, rather than a video format, as no broadcast standard exists for natively transmitting the format, it is regularly used for acquisition and playback of feature films, and it has only negligibly less resolution than the 2K digital cinema format.
