Loved how simply you were able to explain the root cause of gamut clipping and provide a solution for it! Quick question - what do you think about the Gamut Mapping OFX or the mapping options in Color Space Transform OFX? And, yes, please to a video on transfer curves! Thank you, Sven!
Thanks Marieta! The Gamut Mapping OFX to me feels quite useless since all of its functionality is built into the CST OFX as well + I couldn't get the OOTF buttons to do something. It can be used for HDR trims / limiting the peak nit level, but since the CST can do the same thing, I don't see any use in it. Regarding the mapping options per se, I really only use the DaVinci tonemapping. Saturation Preserving as well as Luminance Mapping I don't really like aesthetically.
Excellent presentation with lots of dense Information and nice graphics and animations. Well done, as always. Makes you wonder why some IDTs produce negative values in the first place. I suspect simple maxtrix profiles which retain gradients/color mixtures better than profiles which do complex transforms derived from spectral sensitivity functions of the sensors. Every video of yours has been a banger! Sehr gut, weiter so!
NOIR GRADE! Keep making these videos. They are amazing and true to education, by that I mean your videos help with understanding why this does this or that, or doesn't do this or that. I literally went to film school and majored in colour grading and data management and not once throughout my years did my course touch on or go into as much detail as you. Channels like yours bridge the gap between color scientist and colorist.
I think you should redo this video using concert footage and title it accordingly. There's a TON of concert videographers that would KILL for this info. Thanks for posting. First video of yours I've seen and I just subscribed.
Hmmm. It seems the inverted sat controls I discovered in Resolve 19 in a recent project was likely due to out of gamut colours. -maybe. I will have to revisit with the Aces transform tool in hand. I had already attempted to use Gmut compression but I was fishing in the dark.
TRANSFER CURVE: what is it, exactly? ... i have heard it referenced from time to time but nothing specific. ...(which makes us engineering types not only very curious but anxious to solve nagging problems, some of which we didn't know we had.) Your example image of out of gamut was VERY helpful because I have mistaken that artifact as low-bit depth blocking issues. THANKS!
A display transfer curve is rendering images on a screen, compensating for human perception and the physical characteristics of the display. So basically - taking linear light and converting to log that our eyes see as normal on a screen.
"transfer curve" is just a broader term for log-curve, but it describes the lin to log as well as the log to lin curve. Both come as a pair anyway. lin to log is the OETF, log to lin is the EOTF. The easiest way to learn about this stuff (at least imo) is to just read through one or two white papers. Thanks for the support
Have you used DCTLs for gamut compression? (Had not thought about using Aces for gamut compression capabilities.) Some DCTLs (there are a few) provide controls similar to Aces and also include a graph of the applied compression curve (curves which I don't fully understand). And, FWIW, have you used the DCTL called ClipSafe (free)? This highlights low and high end excursions for easy identification. Use it on all my sequences.
Most DCTLs I tried for that were based on the same math. I believe the original code is by Nick Shaw and has then been implemented into the ACES Transform OFX with 1.3 I did not try ClipSafe yet. Will check it out later

3:08, subscribed for this type of content, and I'd appreciate a deeper dive video!
@@HuysuzVirginia Thanks for the kind words!
Thanks! I have encountered this problem multiple times in resolve and wasn’t aware or this
Exactly the problem encountered yesterday, unexpectedly. Great to see this. Thanks.

That's just by the nature of logarithmic curves and matrices. You will always run into these issues with this math.
Thanks for the support :)

Thanks a lot for the nice words. Really means a lot!

Good point. I'm thinking about it. Thanks for the suppport!

I will have to revisit with the Aces transform tool in hand. I had already attempted to use Gmut compression but I was fishing in the dark.
Many problems are caused by those. Hope it helps and you can find the cause!
More videos about palette and texture please
on my list!
Congrats on starting the YT channel! Looks really good :)
@@thedouglasdutton Merci :)
this is fantastic! - new to this channel - huge fan and learning a ton!
@@CreativeVideoTips thanks a lot!
I'm a fan of your channel.
Excellent vidéo, really getting to the root of the matter in and easy to understand way. Subscribed 🔥🙏
Thank you!

I missed how to deal with the out of gamut colors without using aces…eg DWG

really depends on the LUT. there is no right or wrong per se.
The film noise was very distracting. Maybe use it less please?
Or interpret the framerate so it doesn't jitter and bring down its opacity. Otherwise, great informative video, thank you!
Thanks for the feedback!
