I don't know if "ratio" is the right term, but here is my problem. I have 3 videos for my child which have the wrong proportions. They are supposed to be 4:3 but they are 3:4 and look rediculous... I would like to find a way to for the correct ratio so it is written to the files and remembered.

Anyone know an app that will do this?

QTPro if you have it. Otherwise, I think you can do this with the app I wrote, metadata hootenanny (free). Drag the avi into it, click on the tracks icon in the lower right corner, find the video track, scroll right to the dimensions, edit them carefully, and save as a self-contained movie. Let me know if you have problems with it and I may or may not be able to solve them.

These apps will both transfer the video and audio bitstreams into mov files (not avi). I think this is your only bet, because avi doesn't have a mechanism for non-square pixels.

Hi!

For some reason your app won't open the files, and neither does quicktime pro (updated fully). I can open them just fine with VLC. I had a look at the resolution with VLC and it's currently 384*576. When playing back with VLC it's fine (as I can force 4:3 aspect ratio from the menu), but I want to burn them so he can watch them from the tv, and the dvd-player grabs the resolution from the file.

Then they're not avi files. Asf is my guess. See here: Macos Movie FAQ to see what they really are.
