why is 50.0/60.0

[likemby]

import eulerian_magnification as em

vid, fps = load_video_float(source_path)
em.eulerian_magnification(vid, fps,
freq_min=50.0 / 60.0,
freq_max=1.0,
amplification=50,
pyramid_levels=3
)

Have you solved this problem? freq_min, how freq_max parameters should be determined
