ProRes
ALEXA has been the first camera offering internal, ready-to-edit,
QuickTime/ProRes HD recording to SxS PRO cards. With SUP 7.0, all
cameras received a free upgrade enabling QuickTime/ProRes 2K
recording. Recording in ProRes 2K is a cost-efficient alternative to
shooting ARRIRAW, as it requires less storage space and no
processing, but at the same time delivers an image quality that is
superior to that of up-scaled HD material. With the option to capture
ProRes 2K in the 4:3 aspect ratio, the format offers true anamorphic
capture with regular 2x anamorphic lenses and offers extra room for
repositioning when using standard spherical lenses.
Note: 4:3 ProRes 2K is available on all ALEXA XT models and ALEXA Plus 4:3,
ALEXA Studio and ALEXA M.
