Hi all,
I've been using VirtualDub to edit some Mpeg-1s. And I save them into AVIs. Everything was fine all until today. All of a sudden, every single AVI I create became "squeezed vertically into a widescreen like res".
The source is 352x240.
here is a screenshot of what the ratio of the output avi is like.

Can someone please tell me how to fix this problem. I've tried reinstalling VirtualDub but it's still like that.

Can you try with the official version of VirtualDub instead?

Release build -- 1.6.19 (stable), 32-bit version
I've tried using this version too. (before install I have removed all the previous settings via the setup)
Same problem
a 352 x 240 NTSC VCD file always get the "squeezed down" effect.
basically a
xxxxxxxxx
xxxxxxxxx
xxxxxxxxx
becomes a
xxxxxxxxxxxx
xxxxxxxxxxxx
xxxxxxxxxxxx
everytime I encode. The video always gets shrink down vertically.
This happen even no plugins are used.
e.g.
I open Vdub, drag a NTSC 352x240 mepg-1 file in it. Choose "save as AVI"
and the output is always a shrinked down version.
So, open file > save as AVI = shrinking! |

Ah, I can explain this. VideoCD is encoded using pixels that are a bit wide. AVI doesn't generally have a notion of an aspect ratio setting, so the pixel aspect ratio is reset to 1:1 and you get an elongated video.

it seems that if I convert that avi file back to VCD again.
the ratio is fixed |
