Masking wont remove background?
So, I am using After Effects CC 2017, and whenever I mask, It will show the lines around what I masked, but it won’t delete the background/turn the background black. What can I do to fix this issue? Thanks.

Is the mask mode possibly set to “None?”

Well, I tried doing a smaller mask and it removed the background, but when I try to mask a human it won’t work. Also, how do I check the mask mode? Thank you for your help.

Click to highlight the layer in the timeline. Type “m”. This will show you the mask (or masks) on the layer. To the right of the name of the mask is a drop-down menu that let’s you choose the effect the mask has on the layer: None, Add, Subtract, etc.
The simplest explanation is that the mask is set to None. If not, then obviously something else is going on.

I just masked a human in another clip successfully, however the original clip that I had the problem with wot mask right at all, just the outline at the mask, even when it wan’t set a none. Any explanation?

Not enough information. What kind of layer? Is there only one mask on the layer? How did you create the mask? Have you tried deleting it and creating another one?
Are you sure the mask path is closed?

It is a video layer, I have tried recreating the mask, and yes, it is closed.

Any effects on the layer? If so, try turning them off…?

That did the trick! Thanks!

Great.
If you need the effects, pre-compose the layer with the effects, and then apply the mask to the pre-comp.
