EDIT: Or it does.. how exactly would I need to edit the script for that?
 This is the snippet code in my avs script
displayRefreshRate = 60.000
speedup = displayRefreshRate / last.FrameRate
(abs (speedup - 1.00) <= 0.05) ? eval ("""
   num = 1
   den = 1
""") : eval ("""
   num = ContinuedNumerator(speedup)
   den = ContinuedDenominator(speedup)
""")
This is in python script for vapoursynth
...
from fractions import Fraction
...
target_fps = 60.000
speedup = target_fps / container_fps
if (abs (speedup - 1.00) <= 0.05):
    num = 1
    den = 1
else:
    denum = Fraction(speedup).limit_denominator()
    num = denum.numerator
    den = denum.denominator
Change the displayRefreshRate (or target_fps) to your target display.
After that you should edit the global smoothfps_params to be able to be supplied the calculated num and den
In example, I do it like this (in avisynth) :
maskArea = 0
algo = "13"
global smoothfps_params = """
{
    rate: {
        num: """ + string(num) + """,
        den: """ + string(den) + """
    },
    algo: """ + algo + """,
    mask: {
        cover: 100,
        area: """ + string(maskArea) + """,
        area_sharp: 1.0
    },
    cubic: 1,
    linear: true,
    scene: {
        mode: 3,
        limits: {
            m1: 1600,
            m2: 2800,
            scene: 4000,
            zero: 200,
            blocks: 20
        },
        luma: 1.5
    }
}"""
Below in vapoursynth
...
algo = '13'
maskArea = 0
smooth = core.svp2.SmoothFps(clip, superarg['clip'], superarg['data'],
    vectors['clip'], vectors['data'], """
{
    rate: {
        num: """ + str(num) + """,
        den: """ + str(den) + """
    },
    algo: """ + algo + """,
    mask: {
        cover: 100,
        area: """ + str(maskArea) + """,
        area_sharp: 1.0
    },
    cubic: 1,
    linear: false,
    scene: {
        mode: 3,
        limits: {
            m1: 1600,
            m2: 2800,
            scene: 4000,
            zero: 200,
            blocks: 20
        },
        luma: 1.5
    }
}""", fps=container_fps)
...
Of course I use the script not for encode but only for watching.
