How to apply Lumetri Color "Vibrance" only to the highlights in the video clip

You guys are great. I enjoyed reading posts to respond to this question. Figured the solution would be a mask of some sort ( HSL stand for Hue, Saturation, Luminance ? ) and I've done masks with alpha in CS6. It works.

Resolve is easier cause there's power window and more direct methods, still using YRGB. But that's irrelevant. I would guess that the poster would focus on the 'saturation' area of the adjustment ?? while checking if it effects the other scopes ( rbg parade, etc. ) ??

You can do an HSL key applied in a 3-clip layer stack using Track Matte that will do this. And it's easier than it sounds.

• Hold down the Alt key and drag the clip up to Track 2, so you've got the original and a copy on both tracks.
• Hold down Alt key again, drag/drop to track 3.
• On track 3, go to Lumetri panel, set an HSL key using only the lightness slider to your highlights area with some decent amount of fall-off.
• Leave that layer with the HSL key mask on, set to black/color.
• On Track 2, apply the Track Matte Key effect.
• Set the "Matte:" option to Video 3.
• Set the "Composite using:" option to Matte Luma.
• NOW go to the Lumetri panel on Track 2, and you can apply any control you want, and it will only affect the highlights of the clip on Track 1.

Takes a few seconds to setup is all. And gives you a very clean key from the original image data, so it's useful not only for this, but really for any time you want to pull a clean HSL key in Premiere from original data.

What this does is take the HSL key from the original clip data on Track 3, pass that through the Track Matte Key effect on Track 2, limiting anything done on Track 2 to the pixels passed by the HSL key in Track 3. The resultant work you do is applied to the clip on Track 1.

You could also futz with the HSL Curves some, and achieve something similar.

• Set the Saturation up in the Basic or Creative Tab.
• Use the Luma V. Sat curve, put a point to protect the highlights saturation on the second major graticule line in from the right, then set another point at the middle left-right or slightly to the shadows. Drag this second, left point down a couple lines worth. (This reduces saturation in the lower values.)
• Use the Sat v. Sat curve to set a point in the middle left/right or slightly to the left side, which is the setting for lower saturation values.
• Grab the right end of the Sat v Sat curve and pull down near to the bottom. This pulls back higher saturation values without affecting lower saturation.

Now you can play with overall saturation and the two curves to shape the saturation you want. In fact, you could even use the Hue v. Sat curve to adjust overall saturation instead of the Basic or Creative tab Saturation tool. Just click on the starting line in the Hue v. Sat curve and drag up to increase overall saturation.

One caveat: with the Luma v. Sat and Sat v. Sat curves, don't EVER pull anything above the starting mid-line top to bottom, that can and will induce super-black artifacts. Avoid that mistake, those HSL curves are an awesome tool.

you want to do what's called a "secondary" color correction...which allows you to limit the area that you are adjusting by luminance, saturation and hue.     doesn't look like you can adjust vibrance within a secondary within Lumetri as far as I can tell (doesn't mean you can't do it, just means I don't know how).    You might want to explore blackmagic davinci resolve (there's a free version) that has a more sophisticated interface but there can be a steep learning curve.    and it's possible there are more capabilities in after effects (but also with a steep learning curve).
