I wrote an earlier post about what (little) I know about HDR workflows in Media Composer....http://community.avid.com/forums/t/138226.aspx
After viewing a presentation from Michael Kammes, http://5thingsseries.com/hdr/ , he states that Media Composer can handle HDR workflows; and it does it all automatically, once the HDR input is defined.
In light of his comments, and some of my own questions from my previous post, I'm looking for a white paper from Avid that describes their HDR workflows. Does such a thing exist?
