The DPX files appear slightly less green than the Quicktime. Have you experienced this problem Nick?
Yes I see the same thing. It's part of the joy of QuickTime!
Both Filmlight and The Foundry have had to write their own code to get around some QuickTime limitations. This results in slightly different colour processing.
I'll have to run some tests at some point and try and work out which one is more "correct".
I just did a quick test, using test files that I have as both ARRI RAW and ProRes, and converting the RAW files to DPX in the ARRI RAW Converter gives DPXs which very closely (but not perfectly) match DPXs made in Baselight from the ProRes files. They do not have the green tint present when reading the ProRes directly in Nuke.
