Vizu, the San Francisco-based advertising analytics company, has created a system to track the "brand lift" of online video ads.

It also provides information on how to optimize targets for advertisers and ad networks.

All of these services are provided in real time.  According to CEO Dan Beltrano, these tools make online video more effective and provides much higher rates for publishers.

Here is our interview with Beltrano.  Dan explains brand lift, which means the impact of ad on awareness and on intent to buy.

Late last year, the company raised a $6.75 million venture round from a group of top VC's and individuals.
