New Avid DNxHD codecs
Avid has just made its latest version of the DNxHD codecs available on its Knowledge Base site. Scroll all the way to the bottom to get the codecs.
Import a QuickTime movie that has been compressed with this codec into an Avid editing application as DNxHD. You can “fast import” the movie if you select the 601/709 option in the Import Settings dialog box and import the video as DNxHD into an HD project of corresponding size and frame rate of the QuickTime movie.
Exporting from a non-Avid product: Export a movie at a size of 1920 x 1080 (1080i/p HD), 1280 x 720 (720p HD), or 1440 x 1080 (DNxHD-TR 1080i/p) for optimal quality.
Alpha: This codec supports alpha channels.
You read that correctly. The new DNxHD codecs now support alpha channels – a huge workflow enhancement for those of us using third party applications to create content for our Avid systems.
I haven’t tested them yet, but surely they are worth a try.
