Only the Black Series of HERO3 cameras features the monstrous 2.7K resolution, which translates to 2704x1524 pixels--considerably higher resolution than 1080p HD, which is 1920x1080. Unfortunately, the highest resolution YouTube can display is 1080p, so even this brilliant video isn't as high-quality as the original.
Nonetheless, the stellar image quality, light handling, and clarity combine to give this video a more immersive feeling than you could get--at least for a mortal's budget--just a few months ago. Sound quality isn't so bad, either.
Anyway, enough about the cameras we use to capture our motorsports obsession. Go obsess for yourself as you watch Joerg Bergmeister pilot the Flying Lizard during practice for the 2012 Petit Le Mans.
