The basic principle behind this idea isn't that bad, actually. Speeding up image and audio automatically makes it funny. Call it a parody and CBS can't do shit about it. At home, viewers can then use speed down at their leisure.
I kind of knew the discussion would go in this direction.
If tricks like this are employed in order to satisfy the letter of the rule and not the spirit of the rule, you're gonna get smacked. It's in the same realm as people pitch-shifting copyrighted music or putting a weird effect on video footage to defeat Youtube copyright police. They'll view this as simply a compression mechanism for a long-form video.
Before, fan-films had their own talking points for why they felt what they were doing was not damaging CBS/P enough to illicit a C&D, since there was nothing in writing, only hearsay to go by. But if you go down this road then you drop the artifice about following the rules and it's all about gaming them. This will only reinforce any negative attitudes CBS/P may have about fan-films and make a bad situation worse.
