Internet TV pioneer Hulu is reportedly in discussions to transform its business model. Since its 2008 launch, Hulu has been one of the leaders in free online television delivery and web-video ad dollars.

The Wall Street Journal reports that Hulu’s three owners (NBC Universal, News Corp. and Disney) are concerned that free Web versions of their TV shows are cutting into their traditional business, and the three are at odds regarding how much of their content should be offered for free.

News Corp.’s Fox Broadcasting and Disney’s ABC are considering pulling some of their free content from Hulu (and selling more content to Hulu competitors), while Hulu management is discussing the idea of retooling Hulu as an online cable operator that would use the Web to provide live TV channels and video-on-demand content to customers. If they opt to move forward with such a plan, some form of Hulu’s free service would likely remain and it is possible Hulu Plus could be folded into the new service.

Film editor and sound designer Walter Murch wrote a letter to Roger Ebert in which he discusses the pitfalls of editing and viewing 3D movies.

Ebert notes that Murch is uniquely qualified to comment on 3D, considering he has received Academy Award nominations for films edited on four different systems, including: upright Moviola, KEM flatbed, Avid, and Final Cut Pro. He also edited the 3D “Captain Eo” in the 1980s and wrote “In the Blink of an Eye: A Perspective on Film Editing” in 1995.

In his letter, Murch addresses a number of compelling points such as the inherent darkness of the 3D image, the strobe effect of horizontal movement in 3D, and what he sees as problematic issues involving how our eyes and brain interpret convergence, focus, and immersion. Murch sums up his take on 3D as, “dark, small, stroby, headache inducing, alienating. And expensive. The question is: how long will it take people to realize and get fed up?”
