More from Building Blocks: Short-form vs Long-form, Video Advertising, Google, Yahoo, and YouTube

Just some more notes from the Digital Hollywood event in San Jose...

- Peter Chane of Google Video says the company's goal is to collect "all the world's video," whether it's user-uploaded content, or premium TV shows like `Charlie Rose.' Google wants to "make sure that as videos explode on the Web, that users can find it and that it's accessible."

- Short clips work better than long-form content. They're easy to digest during a coffee break. Established media companies are thinking about how to "chunkify" their content -- breaking longer shows up into smaller chunks.

- Advertisers are still a bit wary about putting their spots in front of user-generated clips, because the content can be low-quality, offensive, or copyright-infringing. They're worried about "inappropriate adjacencies." Still, Jason Zajac of Yahoo said that "the buzz in this space is that everybody's full now" -- there's very little inventory left at popular video sites.

- Oliver Luckett of Revver said that by his tally, there are now 180 video-sharing sites. His company is planning to "open our system" within the next couple months, so that anyone would be able to build a site that would allow people to upload videos to Revver, watch videos from Revver, and make money in the process... what SiliValley types call an "open API."

- Saw a demo over lunch from Andy Leak of Instant Media. He says his site is one of the few that's currently doing digital downloads of high-def content. Know any others?

- I got a chance to talk with Lewis Henderson from the William Morris Agency after a panel, and he told me that many of his clients are thinking about creating short-form videos for the Net, making it for $10,000 or less. But it's still unclear, he said, what the best distribution avenue is for that...where can you make the most money, without signing away all the rights?
