Re:Ask HN: What are some Chrome extensions that you wish you...

A few months ago, I wrote a proof of concept that does this: https://github.com/deactivated/video-snapshot. It seems to still work in Chrome 24.
It depends on the HTML5 player and has a few other limitations, but it might be useful for anyone doing something similar.
I see this being a hard one. I don't even know if that is possible, but I was asked by a designer a couple months ago and he even offered me some money to build that. Taking screenshots from a video source usually render very blurry images, so he was looking for an extension that would do good still images from a video at specified intervals or specific points in time. May be worth trying.
