I think Google/YouTube is already doing this. For example when you Google search "how to reset a Macbook", the top result is a video that jumps to a particular highlighted section that answers the question.
This isn't the best example of this feature, but it sure has saved me a lot of time in other queries that I can't recall at the moment.
Exactly. Google does this through the video transcripts, and finds the query location in the video for you. The problem is that this isn't part of the video player itself (or YouTube search). It's also very basic, being just a transcript search - I want more data mined insights to be available.
