Blur or soften only part of a video. Is it possible?

[nutty88]

I've used the AVIsynth plugin Logotools to remove a logo. Although it hasn't totally removed the logo it isn't as noticable as before. The only problem is that it looks a little sharp. I've tried blurring the whole video which does make the logo alot better but as you would guess the video looks worse. Is there any AVIsynth or virtualdub filters that can blur or soften only a selected part of a frame and not the whole image?

Hi-

One way is to crop down to just the logo, blur it, and then overlay it on top of the original logo in the video. Here's a sample script I was playing with:

A=AVISource("C:\Path\To\Video.avi")
B=A.Crop(38,422,-596,-26)
B=B.Blur(1.58)
Overlay(A,B,X=32,Y=420)

Or, as BJ_M suggested, use a better logo remover to begin with.
