At NATPE, Greg Smith, GM of VideoHub, a unit of Tremor Video, shared observations on the online video advertising market and how VideoHub is differentiating itself. Some of the highlights of what Greg is seeing:

- Segmentation among ad buyers - some that want a full-service model, like the one Tremor Video offers, and some that want a lower-cost, self-service model like what VideoHub offers

- Strong interest in real-time bidding and ongoing desire by publishers and advertisers to figure out how to value inventory

- An explosion in online original video programming that will be monetized through advertising

And more.
