Jackson hopes the 48-frames-a-second rate - twice the 24 frames that has been the custom since the 1920s - will help bring about a gradual transition to faster speeds that can bring more life-like images and action to the screen.
Digital cameras allow for shooting at 48 frames or faster, reducing the flickery, blurry effect known as strobing that can come with 24-frame filming.
Jackson talked about his two-part adaptation of J.R.R. Tolkien's "The Hobbit" at the Sundance Film Festival in Utah, where he premiered the documentary "West of Memphis," produced by him and his wife, "Hobbit" co-writer Fran Walsh.
