How can I make an extension of the same video

[simpluuu]

Hello.

I searched all day long to find a way to make a small video with an extension of the same video but blurred as a background.
Can I add that effect in Sony Vegas 13 ?

PS : my first language isn't english and google didn't help me to solve that problem.

Thanks.

I am sure you can with any NLE.

Basically you put the video on two layers, then magnify the video on the bottom layer all the way to the end of the frames and apply some fast blur.

Yeah, here's an AVISynth script to do just that (or something quite like it):

FrgdVid=last
BkgdVid=BilinearResize(FrgdVid, FrgdVid.width, FrgdVid.height, FrgdVid.width/4,FrgdVid.height/4,FrgdVid.width/2,FrgdVid.height/2)
BkgdVid=ConvertToRGB(BkgdVid)
BkgdVid=GeneralConvolution(BkgdVid,0, "16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16 16", 256, False)
BkgdVid=ConvertToYUY2(BkgdVid)
FrgdVid=BicubicResize(FrgdVid, BkgdVid.width/2, BkgdVid.height/2)
CompositeVid=Overlay(BkgdVid,FrgdVid,BkgdVid.width/4, BkgdVid.height/4)
Return (CompositeVid)

Or you can cut it down even further:

FrgdVid=last
BkgdVid=BilinearResize(FrgdVid, FrgdVid.width, FrgdVid.height, FrgdVid.width/4,FrgdVid.height/4,FrgdVid.width/2,FrgdVid.height/2)
BkgdVid=Blur(BkgdVid,1.58)
FrgdVid=BicubicResize(FrgdVid, BkgdVid.width/2, BkgdVid.height/2)
Overlay(BkgdVid,FrgdVid,BkgdVid.width/4, BkgdVid.height/4)

Just load in your video above the 1st line & adjust for colorspace/framerate/resolution as necessary).

Mine does a resize down of the foreground video rather than no resize+crop (or no resize of FG but non-equal crop with the zoomed BG)

Since this is related to ways of 'stretching' videos, does anyone know if there is a non linear 4:3 to 16:9 stretch AVIsynth filter (e.g. where the stretch factor is zero in the middle of the video and gradually increases towards the sides?
