Basically, I have a video and I want to add the ramp (radial) effect to it. What i want is the corners of the screen to be black but the centre of the screen to display the movie. The problem I have is that the ramp blocks off all the video whereas I only want the corners to be covered up (like a circular photo frame). Does anyone know how i could do this?
As you can probably tell i'm a beginner so I would appreciate simple instructions.
You're thinking about it the wrong way.
Make a black solid, then add your video layer on top.
Select the video layer, then use the Ellipse tool to make an elliptical mask.
Feather the mask to taste. Move it around if necessary in the Free Transform mode:
Don't get no easier than that.

You should take advantage of them.
