This is leaking to loads of other media too - movie trailers have started with some quick action shots, then BIG text saying "trailer starts now". Like a trailer to a trailer. Which is released after a teaser for a trailer. They even have recurring sound effects (vine boom sounds, but movie trailer edition where every action event (explosion, punch, scene change) is accentuated with a distinct drum boom sound effect, often in time with the dramatized remix of recognisable music). I hate it lol.
As for tiktok / other short video clip format content, one trend I've seen is to start the video with the conclusion (e.g. someone falling over), then starting with the buildup. Since these videos are played on loop anyway, they trick the viewer into thinking they missed the buildup.
How I hate the trend of videos like YouTube shorts to almost show the punchline of the video at the start before the full video.
It's not limited to Shorts, even normal longform videos have had this crap for years now. I hate it too - fortunately SponsorBlock can take care of this, they have optional categories you can enable beyond just sponsors, including the "hook".
I was looking into making an automatic detector for this kind of thing (basically detect if anything in the first ~30 seconds repeats itself later in the video, and if so mark it) but my DSP skills aren't up to the task (and turns out LLMs are useless for these kinds of novel tasks).
In my experience an LLM could probably handle this. And it's not so novel. They can make an image stitcher which is basically the same problem.
It would probably need to download the whole video first though, so I'm not sure it would work as an extension. And analysing all frames would be expensive upfront. (If you're using it interactively and waiting for a video to start playing.)
You might be able to get away with just looking for repetition in the audio.
