RED’s been working on a plugin for After Effects and Premiere that will allow uses to natively open R3D files, and it should be available “within a week” (according to RED founder and chairman Jim Jannard on the Reduser forum).
At the moment, Final Cut and AVID don’t have native R3D support, so this is a pretty big boon for Adobe, at least in terms of RED workflow.
