Nvidia Control Panel > 3D Preferences > Choose the .exe you use to boot the game up> set the Anti Aliasing to "Override any application setting", plug Gamma to "on", the one below it to 8x supersampling, and the AA value underneath to 32x (I believe 16Q provides a slightly different effect, but I don't give a ****, since there's 0 aliasing at 32x).
This will eliminate all jaggying completely (perceived anyway - I'm sure if you zoomed in on the images above to 200-400%, you could make them out easily, I can even almost make them out without zooming in, but it's nearly imperceptible)
The video could probably use another pass, on increased brightness. For some reason, when FRAPS captures video, the lighting seems to take a negative notch (in all games).
I wish youtube could process it better (or I could know how/where to filter it so that the processing doesn't affect it as much as it does), but this'll be just about as good as I can get it to be.
edit: excluding recording it over and over and over again until everything in the shots plays out "perfectly".
