    Alexa LUT using Avid Color Correction

    Arri Alexa LUT Color Correction Effects


    Click the link to download.
    Extract the zip file and open the bin in your Avid project.

    Apply the Color Correction Effect on an Alexa logC clip or put it on an empty track above to view the footage in linear space with gamma and highlight roll off.

    Legal maps the footage to 16-235. 
    Extended maps the footage to 0-255.

    Note: The effects are basically 1D LUTs (8bit with 16 samples) and they don't convert properly to Rec709 colors.
    In an attempt to fix that I added a little saturation to the effects with the suffix "SatBoost".

     

    Cool feature:
    Since the s-curve is downstream in the color corrector you can set the exposure by adjusting Brightness in the HSL tab. 

    A brightness value of 18 should be similar to one stop in exposure.
    (36 = 2 stops and so on.)

    Add some punch with Contrast if the Brightness adjustment washes out the image.
