I'm trying to set up a postrender process in nuke to convert the written dpx-files in log-c to prores-quicktimes using rvio.
It is working well apart from the fact that I wasn't able to match the colors to the mov-files Nuke writes on its own using prores 422hq (apcn), sRGB and no gamma correction. I used the -inlogc flag to set the input dpxfiles to AlexaLogC and tried -outsrgb -outgamma 1 and -outgamma 1.8 to set the output colorspace, but there is always a color shift compared to the quicktimes created by nuke.
Has anyone experienced that kind of problem or is there any further documentation concerning additional parameters in rvio when encoding prores?
Thanks a lot,
