3. Re: Method for adding blur to part of the frame
shooternz May 25, 2010 7:17 PM (in response to R-Cole)I saw the screen grab.
Basically a two shot with one person more in foreground than the other (ie.shot on an angle instead of directly from the front). Foreground person is slightly soft focus and the other person is sharp and slightly on the edge of frame. Not sure exactly which one you wish to "blur" or the extent of the blur. I suspect you wish to defocus one or the other more than blur them as in a "Crime Scene" type look.
Maybe of no help but Magic Bullets Looks has a great tool that would work perfectly for this. "Shift Tilt Lens."
I am also not sure how much movement camera or the people have in the frame.
Start here
A simple (crudish) way would be to duplicate the video clip and place one exactly match framed above the other. Draw a Garbage Matte on the top layer loosely around one of the people. Apply Fast Blur or Camera Blur and maybe a subtle darkening to one or the other clips.
Be careful where you draw the Matte. You can not soften the edge of the matte(or invert it) as you would be able to in AEFX. You can animate the matte to follow movement.
Let us know how you get on.

R-Cole May 25, 2010 7:39 PM (in response to shooternz)Thanks again for the suggestion and Email.
I was going to use a simple garbage matte but wanted the soft edge I would be able to achieve in AE. That is why I was hoping to create a matte and have it feathered. I thought I had read about a method to take a screen grab and turn the part I want to keep (soft focus girl in foreground) into an alpha matte and key out the rest. Similar to if I used the alpha mattes included in the Digital Juice toolkits. I just can't seem to track down the method or get it right on my own.
I am not sure what will happen if I try to do this after cutting this into hundreds of clips in my PP timeline. It won't kill me to leave it as is but I know I will need this method down the road and I am sure it can be done. Next time I will need to think about this in advance and mask it in AE before I cut it.
Thanks again for all the help.
