Yes this is possible.
But if the application have the same color on the same spot it’s transparency too.
Other way is to crop the edges or have a black&white mask to do the trick.
Best, benni

Yes,

You'll have to to a little bit of work, but it's possible.

Take your background, cut out the parts you either want to see or not see (you can invert it in Pandoras Box)
Save that as a PNG.

Import it into PB.
Add the effect "Alpha Media as Mask"
or "Alpha Media as Mask Invert"

Apply the PNG file to that effect, apply your input as the source media, you're good to go.
