Hello there Consuelo!
I was just wondering if you ever got around to successfully achieving the transcoding to proress 422 hq? I am currently working on a G5 on FCP 6 and was wondering how to successfully edit. Should I get the .r3d files import them into fcp6 and in log and transfer transcode them to apple prores 422 HQ, or should I get redcine x pro and transcode them to prores 422 hq there THEN import the files to fcp6? And how do i export back to the original 4k resolution once i finish editing? Do I do that from fcp6 or do I export prores 422 hq in fcp6 and then convert them back to r3d in redline x pro?
