Been trying out this conversion for the past few of days. I've only had the GH5 for a few months but I really am enjoying the color response and the highlight rolloff of this profile. I used the LogC conversion LUT, LogC to Rec709 and some temperature adjustments on this one. I've got the original V-Log to LogC frame below. I have not had the pleasure of using an Alexa but your conversion gives the GH5 a better starting point for grading in my opinion. Great work!
