There is no way to rescale a video without recoding. At least science has  
not found one yet.

Some video formats allow to set an aspect ratio in the header, and you can  
rely on the player software to scale to that aspect ratio when playing  
back.

Another question would be, why would you want to rescale a video without  
recoding? When you're not recoding, the file size stays the same. Scaling  
up is useless in most cases. So you're probably scaling down, loosing  
quality, and keeping the file size. Makes no sense to me at all, sorry.
