How much VRAM does Dolphin need?

I didn't think I'd record anything until it suddenly became really easy. I've tried FRAPS as well as Shadowplay, and can say Shadowplay has had better results with less effort. However, I've yet to use it in a game, so performance was never going to be a concern. I've just recorded some general computer use which I've needed to show to other people.
