Further comparisons:
I used just the first part of EP5, because the rest should still be put in sync; color wise, difference of the regraded and the original varies usually from null to small; this is due to the fact RaiTre AR is around 2.0:1, so the automatic color matching script can’t be always 100% accurate; but it does a pretty good job, IMHO.
If there is some interest, I could manage to make a test clip - who knows, maybe also a new project with just color regrading… 😉
