With all the more colour grading demands coming along from shooting with different gammas and gamuts,
What's the chance to get colour grading support for https://www.xrite.com/categories/calibration-profiling/colorchecker-passport-video ?
I believe this is already integrated in Davinci Resolve, Premiere, and FinalCut Pro?
Or does anybody know of a workaround through a 3rd party plugin?
You could use Graide Color Match.
The third party plug for Vegas that i would highly recommend is 3D Lut Creator.
Vegas works with Passport Video. Isolate the RGBCMY chips and after fixing white balance, use the vectorscope to get them into the right positions using color corrector secondary or a better tool like Graide Color Curves.
I've tried automated solutions like in Resolve and it was worse than doing it by hand.
