1. A system configured for interpolating frames of a video, the system comprising: one or more physical processors configured by machine-readable instructions to: obtain decompositions of a first frequency domain representation of a first frame of a video and a second frequency domain representation of a second frame of the video, the decomposition of the first frequency domain representation comprising a first set of sinusoidal functions, the decomposition of the second frequency domain representation comprising a second set of sinusoidal functions, the first set including a first sinusoidal function, and the second set including a second sinusoidal function; determine phase differences between corresponding sinusoidal functions of the first set of sinusoidal functions and second set of sinusoidal functions, such that based on the first sinusoidal function corresponding to the second sinusoidal function, a first phase difference is determined between the first sinusoidal function and the second sinusoidal function; interpolate sinusoidal functions for the corresponding sinusoidal functions based on the determined phase differences, the interpolation of sinusoidal functions comprising determining phases for individual interpolated sinusoidal functions, such that a third sinusoidal function is interpolated based on the first phase difference, the interpolation of the third sinusoidal function comprising determining a first phase of the third sinusoidal function by: adjusting the first phase difference based on one or more of a 2π ambiguity, a confidence factor, or a limiting threshold; and determining the first phase based on the adjusted first phase difference and one or both of a second phase of the first sinusoidal function or a third phase of the second sinusoidal function; and determine information describing spatial domain representations of interpolated frames based on the interpolated sinusoidal functions, such that information describing a spatial domain representation of a third frame is determined based on the third sinusoidal function, the third frame corresponding to an interpolated frame between the first frame and second frame.
