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.
