Peter Jackson has revealed that the Hobbit preview reel he is bringing to Comic-Con is in 2D.

The producer and director also added that although the movie was shot at a frame rate of 48fps (frames per second), the footage will be shown at a frame rate of 24fps. A 48fps preview attracted a mixed reaction at CinemaCon earlier this year.

"I think it's more about protecting the downside, rather than helping the film in any significant way," Jackson explained to Hero Complex at the Los Angeles Times.

"There is a huge audience waiting to see The Hobbit, and any positive press from Comic-Con will truthfully have little impact on that. However, as we saw at CinemaCon earlier this year, with our 48 frames per second presentation, negative bloggers are the ones the mainstream press runs with and quotes from."
