640x272 adding letterbox using virtual dub

[nexus123]

I'm trying to add the black bands to this file using virtual dub resize filter letterbox and resize. Should I use 640x480 as the total size to make it look right on the tv?

If you are using a Divx/DVD player then there's probably no need to add black bars. If you are making a regular movie DVD (ie, you are going to encode to MPEG2) then there are two choices:

To make a 4:3 DVD resize to 720x272 in the top part of the resize filter, then pad to 720x480 in the lower part.

To make a 16:9 DVD resize to 720x362 and pad to 720x480.

If your Divx/DVD player doesn't play the original file with the right aspect ratio try the following:

Use MPEG4Modifier to explicitly set the aspect ratio flag. If the file still plays with the wrong aspect ratio reencode to 640x480 as you originally planned.

I'm going to encode as an xvcd my first attempt caused vertical stretching. 640x480 seems to have left it with to big of a border

XVCD? Then you want 352x136 (lanczos3) for the picture, 352x240 for the frame.
