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.
In 2000 George Lucas announced that Episode II of the Star Wars Prequel Trilogy would be the first major motion picture to be shot 100% digitally. Sony and Panavision had teamed up to develop the High Definition 24P camera that Lucas would use to accomplish this and thus the first CineAlta camera was born: the Sony HDW-F900 (also called the Panavision HD-900F after being "panavised"). However, the science-fiction film Vidocq was actually the first released feature that was shot entirely with digital cinematography.
For Star Wars Episode III: Revenge of the Sith the more advanced Sony HDC-F950 was used, with higher resolution and better color reproduction than its predecessor. The film was cropped to a 2.35:1 aspect ratio from its native 16:9 frame. As a result only 817 of the 1080 vertical pixels were actually used; but there is an anamorphic adaptor lens from Canon, which allows shooting in 2.35:1 without losing any pixels. Manuel Huerga's Salvador (2006 film) is the first movie shot with this adaptor.
