mencoder allows you to rotate images by certain degrees.  See man 
mencoder for its short documentation, but you're better off just trial 
and error I would guess.

And if for some reason it takes a long time to reencode it, just use 
-endpos to test it to make sure its doing it right.

Here's my guess at what your command might look like:

mencoder old.avi -rotate +90 (?) -endpos 10 (encode 10 seconds) -of new.avi
