Commercials on tv have gotten ridiculous

25. I Have Not Detected That

Speeding up would cause obvious changes in speaking parts.
If they used tech to pitch shift back down, it would be less pronounced, but nearly anyone would find something odd, and the speaking cadence would be noticeably choppy.
But, what I have seen is editing out of small pieces. A 2 second aside by one character, a reaction shot from a third person, etc.
Take a dozen 2 to 5 second bits out, and they have time for 3 15 second ads.
Oh, I forgot: I've noticed this on the old Andy Griffith Show that runs on TVLand, or MeTV.
