I have been using the mplayer output to determine what framerate to use,
but your comments have me a bit confused.

If the output is 23.98 fps, wouldn't I use -vfr 1 (24 fps), and if it is
29.97 wouldn't I use option 4 (30 fps)?

I'm not really well versed on the standards, is there some sort of
formula to determine which option is best suited to the indicated
framerate?

Thanks again!
