Depth of Field? (Blurring some area of the frame)

[Outcast]

Is there any method that can be used to create a depth of field effect? Like a certain area of the frame is out of focus. I imagine it could be done with some kind of shader applied to a layer maybe? But it should only be on parts of the screen.. Any ideas for a good way to go about creating this?

The effect I am looking for can be seen in these videos for example:

Have a blur effect on the background layer and foreground objects on another?

I want that effect where the blurring is "on top" as can be seen in the examples i posted. They are covering a bit of the frame area.

Have an rectangular object with a circle cut out in the middle of it. Apply the blur shader to this rectangle and place the rectangle above everything, this might/should work.

I have tried that without any luck :/

How about you try it with a object with an alpha channel so that it's semi-transparent (with the circle still cut out)? Or is that what you tried?

Hm I don't see how having an alpha channel till make anything blury? I found a video with the exact thing I am after, the method is apparently called Tilt Shift and can be used on many cameras.. http://www.youtube.com/watch?v=TwgfsCvxBFg

This does work with the 'Background Blur' shader. I don't remember where I found it but it's here somewhere.

You can even do 'focus shift' type effects by animating the Blend Coeff of your 'lens' active.

Are you sure its called Background Blur? I have searched forums and the mmf stuff page but I find no shader with that name :/

What I meant was that you could use an alpha channel and the blur shader combined. It might not work, but it is worth trying.
