Is there any software that can join multiple avi(divx codec) files of different resolutions without re-encoding them ? I actually have some quicktime trailers that I have encoded into avi but the avi files have different resolutions as I have cropped certain portions of that trailer. As a result some avi ouputs have different resolutions. So how can I join the AVIs into a single complete avi trailer without re-encoding them ? Just to let u guys know that the audio codec & the frame rates of the AVIs are same. Its just the resolution thats different.
