Ken and Dennis did filters 30+ years ago.  Just change from grep and cut to
video/audio filters:

   ... | crop | scale | pad | text_overlay | aknobs | vknobs | ...

text_overlay adds subtitles, closed caption, clock, frame counter, ...
aknobs adjusts volume, bass, treble, ...
vknobs adjusts brightness, contrast, saturation, ...

Smaller programs are easier to understand, write, debug, ...

If aknobs doesn't do what you want, plug in octive_equalizer instead.

If you have a SMP machine, you automatically get parallel processing.

Filters with different licenses can work together in peace.
