I can't seem to be able to find a practical way of blurring out an area of the screen in a scene. Can anyone help?
In the Editor Timeline you'd make a second copy of the clip, blur the top copy and use masks to define where the blurred layer is transparent.
In a Comp Shot you'd add a Grade Layer above the clip, add a blur to the Grade Layer then use masks to define where the Grade Layer is transparent.
A third option is the Witness Protection effect which blurs or pixilates a specific area of the screen. I think Witness Protection automatically blurs an elliptical area, so it might not cover what you want, but it's worth looking at.
@Triem23 That's great! Thanks so much for your quick and informative response. 😀
What if I want to blur the background of the image and make it look like a real portrait?. Is it possible, I guess anyone would guess it that it has been edited since I did not use any tele photo lens for that. Is there any way that I can blur the background to make it look like that it has been taken with an actual tele photo lens?.
@mariah1902 same as above. Masked Grade Layer and a Blur effect. Probably Lens Blur is your best bet.
