I need to cut a hole in the centre of a clip so that the layer below shows through.
The reason I need to do this is their opacities are constantly changing and it creates unwanted shadows where the layers overlap.
An inverse crop function would be ideal. Is there anyway of duplicating this effect?
You can use a reverse track matte to accomplish that.
Draw a white shape in the Titler.
Drop this over the clip.
Drop Track Matte effect on clip.
Set it to the shape and check Reverse.
You can also use the Circle effect to create a round hole.
Drop it on the clip.
Check Inverse Circle and set Blending Mode to Stencil Alpha
