RVIO + OCIO

Hey !

Is Rvio supporting OCIO ? Can't find any related documentations or options.

If not, any plans to add it in the future ?

My use case is really simple, as I just want to do an OCIO colorspace in and out.

Thanks a bunch !

    Hi Marie,

    Yes we do!  RV has had OCIO integration since RV 4.

    You can find the OCIO integration documentation here:
    http://tweaksoftware.com/static/documentation/rv/current/html/opencolorio_integration.html

    Additionally, in the RV packages, there is a sample OCIO color management package that serves as a reference example.  Just go to RV>Preferences>Packages and find the package named "OpenColorIO Basic Color Management"

    The description of that package also has accompanying documentation.

     After checking those out, if you have specific implementation questions, please give us a shout.

     

    Thanks,

    Hi Marie,

    Sorry!  I just noticed RVIO, not RV.

    The above are still valid, but as far as authoring an RVIO session you'll have to build an RV session file to accomplish what you need; so using the RVIO nodes described in the opencolor IO integration guide you can build a session file.

    You can set context variables and the OCIO variable as environment variables before launching RVIO.

    An example RVIO session to work from can be built by using RVIO interactively and then using the "File>Export>RVIO Ready Session" option within RV.

    Unfortunately, there are no OCIO command-line arguments to RVIO so building the session is currently the only way to use OCIO in RVIO.  Building a session, however, can be made programmatically with rvSession.py found in the src directory of RV distributions.

    Sorry about that,

    Hey Michael !

    Thanks for the quick answer.

    Yes, we already use OCIO in RV.

    But my question is about RVIO. Can't find any doc about this.

    I would like to do something like : 

    rvio in.#.exr -in_colorspace <an OCIO colorspace> -out <another OCIO colorspace> -o out.mov

    How about this ?

    Thanks :)

    Yeah, sorry again about the quick response.  If you've already got you OCIO setup interactively, that should be a good bootstrap.

     

    Cheers!
