Ok, so this isn't a scientific test but all I can really do is trust my eyes at the end of the day. I keep hearing some people say that you can only get professional color correction and grading in Da Vinci Resolve and there's no discussion to it. And while I won't deny that Resolve has a dazzling array of features and nodes, more isn't always better. I don't deny that Resolve doesn't have a role to play. I'm just saying for most basic, uncomplicated situations, Vegas can do just as good of a job. But for me, even if I were to use Resolve, I would still do my editing in Vegas.
My test for this is to simply to run the same Log footage through Resolve and Vegas, apply some basic adjustments, then render out some test footage and ask people if they see any difference. And at the end of the day, aren't "people" the final judges?
Below are two clips. Original footage was S-Log3 /SGamut3.cine. I did apply the same S-Log to REC 709 LUT to both and kept the adjustments basic. Nothing fancy, just a fairly out-of-the-camera look. One was corrected in Vegas and the other in Resolve. In Vegas, I was in ACEScc. Do you see any startling differences?
