I find the sound is a dead giveaway for most AI videos — the voices all sound like a low bitrate MP3.

Which will eventually get worked around and can easily be masked by just having a backing track.

that sounds like one of the worst heuristics I've ever heard, worse than "em-dash=ai" (em-dash equals ai to the illiterate class, who don't know what they are talking about on any subject and who also don't use em-dashes, but literate people do use em-dashes and also know what they are talking about. this is called the Dunning-Em-Dash Effect, where "dunning" refers to the payback of intellectual deficit whereas the illiterate think it's a name)

The em-dash=LLM thing is so crazy. For many years Microsoft Word has AUTOCORRECTED the typing of a single hyphen to the proper syntax for the context -- whether a hyphen, en-dash, or em-dash.

I would wager good money that the proliferation of em-dashes we see in LLM-generated text is due to the fact that there are so many correctly used em-dashes in publicly-available text, as auto-corrected by Word...

The audio artifacts of an AI generated video are a far more reliable heuristic than the presence of a single character in a body of text.

Thank you for saving me the time writing this. Nothing screams midwit like "Em-dash = AI". If AI detection was this easy, we wouldn't have the issues we have today.

Of note is theother terrible heuristic I've seen thrown around, where "emojis = AI", and now the "if you use not X, but Y = AI".

No one uses em dashes
