linear workflow (= gamma 1.0) is the prefered way to work in fusion (and it should be in all comp apps)
you have to enable a viewer LUT to see the linear files in sRGB correct way. for this click on the little LUT icon in the viewer, choose a LUT (you can go with the gamut one), enable it, choose edit and set it to output sRGB.
now your viewer will correct you linear files to sRGB for viewing, its only a display correction all you files stay untouched.
now you can do your comp magic to it and if you want to render them out and want to render in sRGB space you can set all on the saver node or just add a gamut node before the saver.
the premult with color needs a little node setup, like this:
- Code: Select all
