HSL Keys in Resolve compared to Color
Ok, my apologies for the generalized question. I have a feeling its going to solicit a variety of polarized responses, but I thought I’d see if anyone else was experiencing similar results or had a bit of experienced insight into this.
I’m having trouble pulling clean/smooth HSL selections in resolve (I use these alot for skin tone corrections as I’m sure many of you do as well). In the past in Color, I could quickly use the eyedropper to pull a quick HSL “key” (on even pretty crappy footage, AVCHD etc.) and signficantly increase/change gamma, gain, hue, and/or saturation on actor’s skin tones (even the muddiest skin tones would work well when a nice key blur of 5-10 was added on the selection). All my corrections seemed to blend very smoothly in Color when using the HSL selections even if the HSL key itself was “dirty” and bled into other unwanted areas of the frame.
When I try and pull the same key in resolve, I’ve been getting some very dirty results, even after refining my HSL selection further (with blur qualifications and softening on each vector). Essentially I get a lot of flashing areas of the frame that pulse and flicker based on the HSL selection and are significantly noticeable when I make a correction like increasing gain or gamma on the selection (just a note, I’m working in 23.98 Progressive 10bit 422 Uncompressed). At first I blamed this on crappy footage, AVCHD, HDV, etc, but then I pulled the project into color and was able to up gain/gamma on the same qualified HSL selection and the results blended nicely without any flickering/pulsing. what?
Does Resolve differ from Color in how it blends adjustments to HSL Qualifier selections? Anybody that’s used Resolve for a long time have any helpful tips on getting clean HSL selections (especially for skin tones). This used to be so easy for me in Color, and now its becoming a hassle. I have to be doing something wrong….

Funny, my experience is the opposite. I always thought Color was lousy at getting good qualifiers quickly, and then was very happy when learning the Resolves….
I finally just learned what the +S and -S buttons do too, so my qualifiers are getting even beter…

Hi Chris,
If you could send us a frame to analyze at davincihelp (at) blackmagic-design.com, that would be great. Please also send the corrected frame from Color and Resolve (apply a extreme grade) so that we can see.
Thanks,

Feel free to expand on these magic +S and -S buttons? There referred to as ‘tolerance’ settings for the key.
What exactly does that mean?j

Second that. A quick heads up on the +s and -s would be of great help.

I wouldn’t call them magic. Just helpful.
All they do is work like the plain + and – buttons right next to them, but with added softness on the qualifier. I’m finding +S is helping get a qualifier quick, and then if I grab too much then I dial it out on the knobs (or use -S).
I was previously hardcore about using knobs to qualify, but realizing the mouse is better to get it started (and many times better in every way).
