Ah, OK, that seems to work. It looks like it's generating one less than 
whatever is specified, any idea what is causing this? I'd like to be 
able to extract non-consecutive frame i.e. 4  frames a second assuming 
the film has more than 4 frames a second. I've tried using -fps but that 
seem to produce apparently random results. Is my only solution to 
extract every frame and then just pick from them afterwards?
