I just found this in the Vision Research press release:
"ACES color space support - convert Flex4K cines into ACES color space by converting them to the open .exr file format – new in this version of PCC."
I hope that is not something you guys know already for a long time, but at least I haven't heard about it before.
So instead of using an IDT, it could be a workaround to convert the media with the PCC tool from vision research and then import it as ACES2065-1 in the desired software. We are doing some tests right now.
Do you have any experience with the ACES export of the vision research tool? Is it somehow reliable?
