Quicktime from Acescg.exr with rvio

RV
1

Hello,
I’m trying to write .mov movies from an .exr sequence in ACEScg colorspace. I would like my .mov to have a Rec.709 color space bakedin.
This work perfectly with RV, but i would like to do it with rvio

I’ ve found here a mthode for doing that (saving an RV session and using the " rvio ocio_session.rv -o ocio_output.mov"

But that does not work.
When i look at my .rv session , the ocio_display par seams empty(but i’m sure to have set it with rv, and the image look great) :
Do you have an idea of what i’m doing wrong ? Thanks

sourceGroup000000_tolinPipeline_0 : OCIOFile (1)
{
ocio
{
string function = “color”
int active = 1
int lut3DSize = 32
string inColorSpace = “ACES - ACEScg”
}

ocio_color
{
    string outColorSpace = "scene_linear"
}

ocio_look
{
    string look = ""
    int direction = 0
    string outColorSpace = ""
}

ocio_display
{
    string display = ""
    string view = ""
}

config
{
    string description = "An ACES config generated from python"
    string workingDir = "/prod/softprod/libs/ocio/aces_1.2"
}

}

We have found the correct way to generate the .rv session file.
By doing File>Save Session As
The .rv session is missing the correct display transform information
We have to do Export > RVIO Ready Session
This was not obvious at all.
In the .rv file we go from this :
ocio_display
{
string display = “”
string view = “”
}

To this :

ocio_display
{
string display = “ACES”
string view = “sRGB”
}

If it can help other …
