I've know that at least DivX files need to be a multiple of 16 on  
each side (most of the time it just gives you a warning when you try  
to save a file that's the wrong dimensions) but nowhere, in any video  
application, on any OS have I ever even seen anything about 'byte  
alignment' when saving videos.

I'd say it's definitely not worth putting that in the UI, most people  
will be absolutely confounded by it, and even the 0.1% of users who  
might know what byte alignment even means, won't know what relevance  
it has to them saving their videos anyway.
