Really stuck! Need help removing nail polish out of video
I really need some help in working out how to remove nail polish from someone in my scene. It’s bright red and I can select just the red color in fcp but cannot come up with any suitable way of returning it to a normal skin tone color.
What effect can I use in after effects to just select the finger nail color, turn it to a grayscale and then tint it. If I can’t remove it my footage is void 🙁 please any help is most most appreciated!

Could u just do some secondary color correction on it? Try and make it match the skin tone.
Easy in apple color or davinci resolve light

I’ve never used color but happy to learn if this will solve the problem! The only time I looked at color I noticed secondary to make a vignette? Is that how it works, inside a vignette?
-
Yeah. In the secondaries you can use a color picker to isolate a color you want to change, then use a vingette to mask out any extra spots that are also red so you dont change those aswell.
Best of luck, look up a secondaries color tutorial if you have trouble

Re/de-coloring is the easy part. The difficulty will involve selecting the areas for secondary grading. This is where tracking comes into play and where mochaPro or mochaAE will be your best friend.

I know how to use mocha well. So do I track the shots and attach the masked secondaries over the originals?
-
That or use the track data to track masks on the mails for color correction.
My guess is that you could use a Color Range Key to isolate the nails without the need for tracking. You can use the matte you will get this way for all layers of color correction you need. I think in AE Colorista -free version (Red Giant)- should work well for what you need.Tudor “Ted” Jelescu

I suggest that you try Ted’s idea without tracking – simply because it’s faster. The final solution you find, depends on the other colors in the footage as well as the frequency and severity of any occlusion of the nails.
If you are going to use mochaAE/mochaPro for tracking, then export mocha’s shape layers into AE and use that as a Track Matte for your graded nails.

Ok, so I’ve gone through and learnt majority of color. I have a question though i cant seem to find an answer to online, that would help me greatly.
I create a nice HSL key in the secondary room, and keyframe a vignette around the nails as they move (massage scene) (shoots himself). Now i’ve shifted the color from a deep red, to what I think is a satisfactory palish pinkiness. But, the killer here is that the nails still have the shine, as if they are painted, and I was hoping to remove this or at least reduce this, with the use of a blur FX.
So my question is, how do I get the FX room to use only the HSL key I have created in the secondary room?
I notice the HSL key node in the FX room, but this makes me create a new HSL key AND it continues on with the modified image from the secondary room, which means I have no RED nails to select a HSL key from on the FX room.
How do I go about using the HSL key matte input from the secondary room and its vignette, for use in the FX room?
-
The fx room kind of works independatly. You will need to create the hsl and masking there aswell to get the blur to stick. One note is the hsl will always work from the original footage, so when you select the finger nail your still picking red not the new color.
Wish I thought of that first so it wouldnt have to be done twice. -
Ahhh shame.
When I click on the HSL node and use the eye dropper in the fx room, it shows me the primary and secondary corrections on the footage. It doesnt seem to show the orginal file as you say?
Any suggestion on that one?
