How to make object darker in Mask?

[Nirr1994]

Hey everyone

i use some effects and masking for soccer players edits 

when i put my effect on clip and do tracking motion is all fine the only problem i have after i do the mask and use ultra key is that the effect is still visable around the player like i see that going thourght the legs in the effect i use 

i would like to know how can i do that the area of the mask will be darke and i will se only the object i want and not the effect in that places

look on the lef area, the effect still visiable

Sorry, might just need some more info. I can't really tell what you're trying to point out.

If you are layering several different effects, it could be helpful to add a nest, like after your Ultra Key, and then do some masking and color grading on the other side of the nest. But I can't fully picture what you have going on.

Hey if you look in the player leg you can see is a bit bright and you can see a bit  lines of the effect going in the back of the legs and on that area i was the mask

i want to do that the area of the legs will be more darker then the effect will not show inside the legs

you can see wher i put the grey circle now

If you're trying to cut out the circles behind the player you would either want to 1) make the player not transparent. or 2) put a mask on the circles behind the legs and invert it (subtraction) so that the lines disappear.

can you have some guide how is best way do the mask on the circle and then invert that?
