# Weight to place on each component when calculating frame score (the value
# `threshold` is compared against). The components are in the order
# (delta_hue, delta_sat, delta_lum, delta_edges). Description of components:

#  - delta_sat:    Difference between saturation values of adjacent frames
#  - delta_lum:    Difference between luma/brightness values of adjacent frames

# the weighted sum of all components.

# than or equal to 3. If None, automatically set using video resolution.
