Thanks very much. This was exactly the problem I was having and the 
solution I was after.

I knew that input options precede the -i, but I'd misunderstood the 
logic and mistakenly thought that an image sequence would have a 
framerate applied when it was output, rather than when it was input. Now 
that I've added the extra -r it works exactly as I'd hoped- and 
incredibly fast too.

Thanks again
