Great so I can see the highlight of the video and then close out before the ad?

this is peak physiological manipulation

And this is news?

It seems to me that YT has been doing that for quite a while already.

So once I see an ad, I know that the video has peaked and can stop watching? Cool

No I won’t ;)

This sounds like an upgrade from them showing me ads before ‘peak’ moments

When i started seeing these waveforms on the playback controls, i wondered how they could be profitable. Now I know.
