I have a question about LogC as well. Do we need a different LUT to work with Amira LogC footage? I’m pretty sure the camera tags the clips, and for instance Premiere reads that and displays the footage with that lut so the editor (and client) see something reasonable i.e. not flat LogC like it is looking at the raw clips. But Nuke displays the footage quite blown out. I know the data is there, but is the AlexaV3LogC not the right transform?
