I have a video clip in which two men are talking to each other ..I want to blur only one man ,who is not talking .
I Used Pen tool and draw sketch around the person ,i wanted to blur ,and then goto effects and apply Lens Blur , but it produced Blur on the whole clip .
Kindly guide Me :)
Try making a solid of any color, using the elipse tool, placing the solid over the guy you want to blur and use the mode Add. Press M two times like MM and feather the solid, so you can see the guy's body/head. Press on the solid layer and go to effects and apply to blur. Should work, not sure tho.
Charlie's idea is actually a better solution so long as you make sure the solid layer is an adjustment layer (look for a check box for the solid layer in a column denoted by a black and white disk).
Make sure the adjustment layer is above the video layer you want to affect.
