I want to add a black border at the bottom only of each frame in Virtualdub but don't know how to do it. With the resize filter (expand frame) it can be done but you get borders at the Top & Bottom. I want to use this bottom border to place subtitles in.
At present i use a workaround with Avisynth's
AddBorders(0,0,0,BottomBorderSize)
function but this is slow because I need to frameserve twice.
Thx for your help.

Try add a border on both top and bottom and then crop the top border using a null transform filter.
