linear resizing filter for virtualDUB

[benderman]

Is there a linear resizing filter for VD? When I shrink a video only in horizontal direction (i.e. from 720x576 to 512x576) the video seems to be smoothed in both directions if I use bilinear or bicubic resizing. Is there any way/filter to keep the sharp picture when resizing?

Try adding on the "unsharp" filter, following the resize...

Yes, I know that filter, but I don't want to reduce the sharpness (resize) and repair it afterwards (unsharp). I hope there is an other way to resize without that much smoothing.
