Grade School: Pro Colorist AMA about LUTs and Color Charts

This week's live is covering questions around LUTs' strengths and weaknesses and how you use color charts effectively.

00:10 Introduction
2:31 Why is preserving middle grey important? Doesn’t preserve middle gray imply that the clip is already correctly exposed?
9:12 Technical problems
14:13 Why is the spike in the histogram after looking at DWG middle gray not sitting at 33.6 but at 38.4 instead on the 0 to 100 scale?
18:36 What are your opinion about the LUTs that you can find in the camera raw tab?
19:50 How does the highlight roll of or the soft ceiling in your 2383 for DWG interact with a higher need HDR deliverable?
27:13 When delivering for SDR your 2383 for DWG also has a limited maximum brightness. How can we achieve a purer white while using your LUT?
33:20 What should your color management be in the project settings if you’re doing color management in nodes?
37:49 Why do we need the timeline luminance option? Doesn’t that break the sense of a scene referred workflow?
40:03 When is it useful to change the node gamma to linear?
43:00 Have you ever experienced that after using a CST the clip breaks or doesn’t yield the desired results?
47:47 Is there any difference between the color coordinates between photography and video?
49:14 Wouldn’t the choice of Rec709 scene for the timeline color space come from the assumption that your Rec709 footage is encoded in BT1886?
53:07 How do you create LUTs that work in DWG?
58:42 Why there isn’t a version of the Voyager LUT pack for ACES?
1:02:37 Is there any reason to do color management if your clips come in REC709/Gamma 2.4 and you deliver REC709/Gamma 2.4?
1:06:24 Should we grade in HDR or SDR first?
1:10:54 What kind of operations you use to create your LUTs that are not available in Resolve by default?
1:17:00 How can we create a camera LUT for a blackmagic camera?
1:24:20 How can we use a plugin like Filmbox to create camera LUTs? 1:29:02 Conclusion

Jesus Christ, more on look development please! Both inside and outside DaVinci as far as I'm concerned :D

Great episode. Thanks for all the knowledge. Love the DoubleHeader.

Loved this one, a bit sad I didn't get to attend it live but many good bits of information here !

How can I mimic Kodak’s 250D film color science in DWG, yet delivering to Rec709?

about prepping a look based on 18%grey, i don't like how the split tone color affect the skin that match when you set your final exposure on shot level like for exemple low key lighting , so i set the final exposure that i like, then with eye dropper i click on fill side of the face, and make split tone based on that for the whole sequence
it's all about either you like or not :)

If we talk about Camera viewing lut should we include the -1 stop exposure node to compensate and make the image ettr?

Is it necessary to stream video 60p? Could work better in 30p or even 24p mode. Less bandwidth needed and a better end result?
