I’d also like to add, though I’m sure it’s too late now, that when using Red footage you should not be using any LUTs pertaining to LogC colorspace. the LogC standard is an ARRI exclusive gamma curve with very specialized math that allows for the best encoding of light onto the ARRI sensors. In essence, LogC is a standard written by Arri, for ARRI footage, from which you can decode to common gamma curves: Rec709, linear or common log. Because LogC gamma curves (there is one curve for each ISO setting on the camera and each curve yields the best results for footage shot at the matching ISO), are specific to ARRI Alexa clips, using them on Red footage will create possibly undesired results and may make it next to impossible to create a true Rec709 result.

Nuke and Flame both have sophisticated pathways for importing Red footage and giving you control over precise image and color settings.

I hope this helps more than confuses.
