    Takes the *input_movie* and the 
    *results* dictionary from spyboat.processing.run_parallel

    For the period snapshot also the period range is needed,
    hence the analysis dictionary 'Wkwargs' also gets passed.

    The output files name pattern is:
    [input, phase, period, amplitude]_frame{frame}.png
    and the storage location in *img_path*.

    These get picked up by 'create_html'
