@balazer Thank for your suggestions about S-Gamut colors, they are very very useful!

@flablo you have to make sure the exposure is perfect to get the correct lut output.

I did this grade in 30 minutes using the ACES workflow in Sony Vegas Pro 13:

The source video is vimeo.com/99411494

That's an average of about 90 seconds per shot. It was just a little exercise to see if I could get decent results quickly, and to demonstrate how a video recorded with S-Log2 gamma and S-Gamut color can look when processed properly. Actually I can't say that the video wasn't mangled somehow between the camera and the original Vimeo upload that I used, but it seems pretty good to me. The DNxHD upload is not correct: it has levels mapped improperly and looks like it may have used a bt.601 Y'CbCr color difference encoding matrix instead of bt.709. I used Vimeo's compressed MP4 instead.

I'm by no means an experienced color grader, but still, I spent just 30 minutes start to finish on my first attempt, including the time to split between shots. (but not including rendering time, which was another 20 minutes or so) I just did basic color correction: exposure compensation and color balance on every shot, and contrast tweaks on a few. It's just a matter of dragging a few sliders until the image looks good and matches the other shots well. I certainly could have spent more time tweaking and matching, but I didn't want to spend too much time.

Some of the original shots were badly underexposed - especially the talking head shots. Exposure compensation does what it's supposed to, but still those shots look worse, with some noticeable color precision errors and noise. Though after Vimeo's and YouTube's compression, you can hardly see those problems anymore.

Nothing to exciting here. It does boot up a bit faster but nothing else has been addressed that I can see
