ARRI announced today that Avid’s DNxHD recording codec would be supported in all ALEXA cameras. The format is planned to be offered as a paid software license to be released with the free ALEXA Software Update Packet (SUP) 6.0, scheduled for January 2012. Upon initial release, the license will offer DNxHD 145 (1920×1080, 8-bit) and DNxHD 220x (1920×1080, 10-bit), with the free addition of the recently-announced DNxHD 444 (1920×1080, 10-bit) in the spring.
Apple ProRes has been a purchasable option for SxS card onboard recording for more than a year. Soon the ALEXA will offer either or both recording formats to more comfortably fit into a production’s workflow. DNxHD 220x has a similar file size to that of ProRes 422HQ, so it should take up about the same amount of space on an SxS card (21 minutes on a 32G card).
