I'm encoding a 16:9 film for DVDr. My Aspect Ratio is set-up to 4:3 (No borders, encoded as 4:3) My Resize is set-up to DVD(720 x 480/576) How come the output I'm getting still have borders at the top and bottom of the screen? I have no problems when encoding SVCDs. [edit] I'll answer my own question after reading the FAQ. To change from widescreen to 4:3, add CROP command in Avisynth as follows: CROP(90,60,540,360) The above still shows elongated faces. To fix, crop more as follows: CROP(90,70,540,340) This will improve it but you will lose some film area. Well, there is always a tradeoff.
