OK... not an official test yet, I did get a little bit of time on an HP Z800 workstation. I installed MetaFuze v1.3 and transcoded a single 01:30:00 R3D file to DNxHD. The R3D was shot 2K/16:9. Storage subsystem was a raided 16bay SAS. The file had no audio.
Full debayer: 04:30:00
1/2 debayer: 01:11:00 (faster than real time!)
Benefits also include native MXF wrapped DNxHD so editing can start right away and not have the additional "fast import" step. Consider this a sort of "off the record" test, but things look quite promising. It was great to see all processors slammed at near 100%. Kudos to the Avid DS engineers!
