It is something that Alexa users have been asking for, and Arri has been talking to Avid about, for a long time, and will mean that Alexa will be the first digital cinema camera to have built-in DNxHD support, although it is possible using external recorders.
Media Composer version 6 now offers the Avid DNxHD444 codec, which will permit customers to preserve the high colour information in Alexa footage while still having a low bit rate codec suitable for editorial. This is great news for Arri and Avid customers, who will benefit from the advantages in quality, speed and streamlined workflows.”
DNxHD recording for Alexa will be available as a paid-for software download in January and is now entering Beta testing with several broadcast productions. The first roll out will support up to 220Mbps 10-bit recording (plus up to 145Mbps at 8-bit), with support for DNxHD 444, at 440Mbps (10-bit) to be provided as a further upgrade for all adopting customers during the first quarter of 2012.
It will mean that Alexa users will be able to record Arriraw uncompressed 3K images as a digital negative for mastering and feature archival use, and/or DNxHD or ProRes for offline, dailies and general broadcast post production.
