/** A film of F seconds at f FPS will be Ff frames;
    Consider some delta FPS d, so if we run the same
    film at (f + d) FPS it will last F(f + d) seconds.

    Hence the difference in length over the length of the film will
    be F(f + d) - Ff frames
    = Ff + Fd - Ff frames
    = Fd frames
    = Fd/f seconds

    So if we accept a difference of 1 frame, ie 1/f seconds, we can
    say that

    1/f = Fd/f
    ie 1 = Fd
    ie d = 1/F

    So for a 3hr film, ie F = 3 * 60 * 60 = 10800, the acceptable
    FPS error is 1/F ~= 0.0001 ~= 1e-4
