Hi there! I just played around with the OCIO nodes/modes in Nuke 6.3v8. I also had a look at the ACES workflow/config from the opencolorIO.org website. I've added this 'aces' config to Nuke by adding the config.ocio as the custom config.
Seems to work fine so far. But there is one thing in this whole setup/config that I doesn't really get: how do I use sRGB/rec709/video footage (stills and/or movies) in a ACES environment? Normally I'd assume to switch the Read node to raw and/or linear (because the Read doesn't support OCIO yet), add a OCIOColorSpace, set IN to something like sRGB/rec709/etc. and the OUT to aces, to convert the image to the ACES colorspace. But there is no IN setting for sRGB/rech709/etc.! I can convert ARRI logC, analog film scans (cineon coded), sLog, etc., but not 'video' or other display referred encoded material (neither in the iff config coming by default with Nuke nor in the aces config from opencolorio.org). So how am I supposed to use still images, video stock footage, etc. in an ACES workflow in Nuke? Only way I tried it at the moment was to switch the Read to "sRGB" (or rec709 or gamma 2.2 etc.), add a normal Colorspace after the read that converts from linear to AlexaV3LogC and add a OCIOColorSpace with IN = 'logc' and OUT = 'aces'. Seems to work, but doesn't seem to be a clever way. Do I miss something or is this just not supported at the moment in this ACES config/workflow? Using the 'spi-vfx' config in comparison, there is the option to set the IN to 'vd8' or 'vd10' or something like that. But 'spi-vfx' is not using the ACES colorspace, right?
