Again, guys, a beginner's question - but here is something I don't get about masks in general, a difference in the way I would expect opacity to work and how it actually seems to work.
I'm using a still image as a sample:
Now I mask it:
And now I would expect that the upper of the two sliders I marked with arrows ("mask opacity") would allow me to fade the mask itself out so that the image below becomes visible again, while the other slider ("opacity") fades the layer itself out. Instead, both of them fade the remaining (unmasked) part of the image out:
What good is that? And is there a way to accomplish a fading mask without putting a duplicate layer below?

A mask will mask the area out. If you have two masks. You can fade one out separately. You can have as many masks as you like on the layer for each Effect. The picture below shows 2 masks. So you want one mask covering the entire image and one mask covering part of the image then you can fade out the bigger mask to leave the area you want in view. Does this make sense? Hope this helps.
- Mask 1 has the opacity of 98%.
- Mask 2 is set to 79%
- Finally the clip Opacity is set to 89% so both are more trans

I didn't get the idea to just use another mask, I thought that'd interfere with the first one. It seems unnecessarily complicated, too (from a software design standpoint).
Maybe, but when combining multiple masks it is very useful.
