    Hey everyone, I noticed a basic 16:9 effect for 4:3 footage which I'd like to do.
    It basically looks like the edge of the video frame is duplicated to the width of black bar and Gaussian blurred.
    Is this something that can be done with virtualdub?

    "I sore"??? Whatever language you guys speak in Oz, it sure as hell isn't English.

    For non-native speakers, I guess he means "I saw" and he's either an idiot who doesn't know better or it's a really really bad joke.

    I can't help but seriously, writing crap titles like that is no way to get help here either. We have a lot of non-native speakers who participate in the forums.

  3. I don't know of anyway of doing what you want in VirtualDub. You can crop in VirtualDub but it doesn't really have any way of adding to the frame (other than pillarbox bars). It could be done in AviSynth which can crop away and add parts back to the picture.

    AviSource("filename.avi")
    #assuming 720x480 4:3 DAR frame:
    left=Crop(0,0,88,480).Blur(1.0)
    right=Crop(632,0,88,480).Blur(1.0)
    BilinearResize(528,480)
    StackHorizontal(left,last,right)

    I would try a nonlinear stretch instead:

    WarpedResize(320,188, 0.7, 1.0)

    More in line with the effect the OP asked for (duplicating the edge pixels) would be to do this, using a negative offset on the resizer:

    AviSource("filename.avi")
    #assuming 720x480 4:3 DAR frame:
    BilinearResize(528,480) # convert to 16:9 DAR
    BilinearResize(704, 480, -88, 0, 704, 480) # stretch to final size

    The porno itself shouldn't make you sore; it may be the activity you're engaged in while watching it.
