Why colorists prefer THIS saturation trick?

Let's discuss a process of achieving a film-like saturation on your digitally shot footage that is more subtle, dense, and pleasing to the human eyes.

I appreciate the effort of spreading knowledge but you rip some of these tricks from the Cullen Kelly's youtube channel. Some credit could be sweet just saying.

Thanks for going down to the point, man I hated so much when people, try to be comedians and waste so much time, explaining their point. Good video.

I like the fact that CF still pinned this comment even though it may not have been a thoroughly researched accusation. I’m just thankful for the content be modernized for YouTube consumption. I don’t think either are the originators of the concept, but each created and put work into the way it’s represented in this format

Indeed an awesome trick! Little note, the timeline color space in the project settings needs to be correct for this to work properly! For example if your working with LogC footage you need to tell Resolve so that it uses the correct math when doing in-nodes-transformations like this one. To make sure you don’t get unwanted result 👍🏾

In this case the node is doing :
Timeline Color Space -> HSV -> Timeline Color Space

wow that made a great change in the color thanks

[winngh]

where have you been all my life in my journey to colour grading! ❤️

[SWFTProductions]

This was really helpful and simple, thank you 🙏

Great trick! Thanks so much for sharing!

Cullen Kelly has done a much more detailed video regarding the same, I would recommend everyone to try watching that as well.

HSV node can and will produce visual ARTIFACTS if there is some degree of negative values in the signal!

They look like strange blue pixels that appear in the dark areas of the image. No adjustment is necessary to observe this effect - just place HSV node in a sequence. An image after HSV node is NOT recoverable. HSL node produces artifacts as well.

How negative values are produced:
1. Signal itself can have some values below zero, because manufacturers "clip" some noise floor values below black point.
2. By basic operations like Lift and Offset. Do not use them for big exposure or contrast adjustments.

Contrast with curve, HDR Wheels or Contrast slider with box "use S-Curve for contrast" ticked won't produce them.

If you want to use both Offset and Lift wheels without risk of artifacts:
1. Use HSV in parallel node at the beginning of the signal chain (like Cullen does). Won't help if the signal has a lot of negative values from the beginning.
2. Use HSV in Color Warper node. You will see that the signal is looking weird, but saturation adjustments inside the grid will look fine.

There are more potential issues with HSV. For example, noise in the neutral areas of the image when using Gamma wheel or sometimes even Gain wheel.

I'll try to make separate video to showcase these problems and ways of resolution. Meanwhile, I'll post this comment to the videos that promote HSV adjustments.

Please keep up the good work. I also watched Cullens work. Both of you guys presented info uniquely and have helped me a bunch. Much appreciation.

Super neat trick, thanks for sharing!

You should leave the Spanish subtitles option active, there are people in Latin America who follow them, greetings from Peru! very good content!

[andresasindop]

Thank you again for such valuable information! Greetings from Spain

This is solid - adding this to my work flow

[movie-trailer]

excellent technique of applying cinematic saturation to frames 👏

[DaveSaintL]

I didn't listen to the whole thing but you should note that this adds chroma noise more more then the typical saturation would. Your actually tearing apart and separating the numbers when it comes down to the math. There are some "expensive albeit" DCTL's that can do this without adding chroma. Still a great trick. love it. but just thought I'd let everyone know... Of course, the better the caemra codec the less this is an issue.

I think the dissemination of Internet video itself is for discussion and learning. I also watch the video of cullen Kelly. I respect him very much, but I think many people are too mythical about him. First of all, the hsv mode itself is to isolate information interference and skim brightness and hue Interference, this is not the only solution, I think this solution is very good, but I have my own solution, that is, I use the layer mode on the dedicated saturation node, I change the mode to saturation, then the same Whether it is the curve or the color wheel, the influence on the picture is limited to the saturation. Of course, I have also studied the usage of other layer modes. I just want to say that we are all just standing on the shoulders of the predecessors to provide new ideas and ideas. method, there is no need to overly myth some people, or be harsh on some people

Isn't this identical to just using the Lum vs Sat curve?
