    I wonder what would happen if I ran my rendered footage through this again?

    you can keyframe issue areas as well. it’s only as good as the algorithm as it averages every thing it sees. highly saturated objects will skew results, so you can mask them or use arithmetic effect to clip certain values out.(I haven’t added arithmetic effect feature yet)

    Where would I place the arithmetic effect? What settings would I put in the arithmetic effect?

    i fixed the pixel aspect ratio, fields, layers, comps. etc.

    I split apart the code for the hue precomp and added an arithmetic effect in it
    so you can lower, for example, the blue channel and it won’t use that to calculate white balance. you can keyframe it for difficult shots. Worked really well for the cell phone shot.

    I moved the hue, color, gamma, layers into the final output comp so you can color grade separately from the algorithm.

    That’s awesome! But for some reason, my CS6 can’t open this one.

    Thanks!

    As an aside, I’m going to be adding this process to the footage. I’ve used it before, and find it superior to many plugins, and even Neat Video in some cases. I know this is probably amateur stuff for you, but I thought I’d pass it along:

    you may find this interesting. this is an autograder prototype proof of concept

    It sets black point, white point, 3 points of white balance, 18% gamma, RGB 204 saturation per frame. I tested it on a few clips. It will even work on log footage. Some things aren’t perfect with log/linear, but it demonstrates that it is possible to grade everything automatically. I haven’t coded perceptual gamma so if a very large dark object takes up the whole frame, it will try to get 18% grey still.

    I also tested it on some Arri log footage and it came out good. Might be useful for quick ‘n dirty output for web based articles. You will still need color graders for perceptual grading as pure math will never give you exactly what you want all the time.

    The only two sliders left are in final output comp, master sliders black point and white point that you can offset.

    I’ll definitely take a look at it. I was able to calm the fluctuation between cool and warm white by putting it in Premiere, and using color correction to essential desaturate it a bit. But any time I try to add a bit more contrast the fluctuation comes right back. I’m rendering out what might be my last try on this. But maybe I’ll push the final product through this auto grader.

    And thanks again!
