Greyscale takes no arguments, so it can't be animated.

You can work around this by creating your own user-defined function to act as a wrapper.

function GreyscaleWrapper(clip c, string unused)
{
    return c.Greyscale()
}

ApplyRange(1416, 1801, "GreyscaleWrapper", "")

Or, a more general version:

function NoArgFunctionWrapper(clip c, string f)
{
    c
    return Eval(filter + "()")
}

ApplyRange(1416, 1801, "NoArgFunctionWrapper", "Greyscale")
