Ask HN: Would you use this service? Video summarization/digesting

I've been thinking about a simple web/mobile app idea, and thought I'd throw it out there to the HN community.

The problem: Almost every day, I come across a video that I'd like to watch, but I don't have time. For example: Tech talks, conference presentations, product or company demos, and so on.

Proposed solution: A simple on-demand video summarization service. I know transcription is available many places, but I don't want a 20-minute video to turn into 20 pages of text. That won't save me time. I want the bullet points, created by someone with solid critical and analytical skills.

I'm not aware of such a service available right now (maybe I just haven't seen it).

Would you pay for it? I think I would. Maybe $5 per video? $1? As a monthly service?
