I suppose you could create an INI file which contains all your output 
options, and then dynamically change this file using povray file I/O.

But then the details of getting it to automatically render two in a row or 
however many are slightly beyond me, since when rendering an animation, it 
doesn't re-read output options between frames. 

Though if you're using a command line version of povray, this task could be 
made much simpler by just making a shell script that invokes povray with 
different output options however many times or different ways you want.
