FVL, or Fourier Video Loop, is a command-line utility to seamlessly loop frame sequence (enumerated .png images) by cutting spectrum of per-pixel transformation over time. More precisely, the time series of each pixel channel, considered as a signal, is approximated by the partial sum of its Fourier series. Using Fast Fourier Transform to switch between the signal and its spectrum, we nullify or reduce some frequencies to decrease the leap of the signal at the ends of the time interval.
