    Source Colour space for 10 bit stills

    Hi

    I am getting a colour shift when importing 16bit uncompressed .tiff files saved with either ProPhoto or Adobe RGB (1998) colour profiles and can't find a source colourspace in "Source Settings"

    The images are being exported from Capture One Pro.

    What is the best way to deal with it whithout going 8bit sRGB?

     

    Thanks

    Re: Source Colour space for 10 bit stills

    Try the source color space setting: "Rec. 709 [video levels]". This will import colors without modification to video levels.

    Hi Joachim

    This is the exact issue; Avid MC is not reading the colour space of the file as there is no source colour profile for the standard images except sRGB which is ideal for 8bit images but not 10bit.

    Is there a way of installing a Adobe RGB (1998) as a “Source colour space”  in Source Settings?

    Rather than use Rec. 709, you might want to consider using Rec. 2020. It encompasses then entire range of Adobe rgb (1998) and almost all of ProPhoto. This assumes you're in a Progressive project (Rec. 2020 is not supported for interlaced).

    Re: Source Colour space for 10 bit stills

    Hi DStone

    I don’t think rec 2020 will work for now as yet there is still no way I can convert stills to rec 2020 or rec 709.  I will just convert stills to sRGB.  Its not too serious as the output is still 8bit 422.  My projects and all the footage I receive from our camera’s is 10bit rec 709 though.

    I thought I was just missing something.
