[Peter Chamberlain] “I doubt they could be changing Alexa settings while decoding red raw”
They could be interpreting the Project Settings… Camera RAW… default being ARRI Alexa as the option that was chosen, but I personally don’t think this is how that dialog works.
I also doubt that there would be any change in behaviour even if the “Red” option is opened in that dialog. Among all the metadata hierarchies in that subgroup, assigning ARRI color science just isn’t available. I thought that that particular configuration really just told the rest of the application how to deal with different RAW formats IF that format were presented to it in the Media Browser, and consequently how to present it to the Edit page for inclusion on a COLOR timeline.
My bet is that the original colorist either adjusted the RAW settings on a per clip basis and those settings haven’t made it into the project export correctly (did not check “Save with Version”, or used a “project settings” default, maybe even a proxy that infers an Alexa profile since that is also the default RAW decode that is displayed on the COLOR page, but isn’t actually applied. When I import R3D clips onto an otherwise default timeline, the Master RAW settings automatically select RED, at least on my system. It would take some very deliberate reassignment to mix the camera deBayer strategies.
