1 Even though the official name of this codec (pronounced “ProRes four by four”) contains four fours, ALEXA records three (444). The fourth digit stands for an
alpha channel that can be used in post but has no relevancy for image capture in the camera. ProRes 4444 is not available in High Speed mode.
