Subject: Re: single pass .rvf video conversion with DirectShow filter
From: Joseph Jones (
Date: 2004-04-04

One thing I forgot to ask, will the resizing maintain aspect ratio,
adding borders at the top/sides if necessary? Say if I fed it a
widescreen file, without borders at the top and bottom, so it's
widescreen aspect, will it preserve that?
