Yet another significant company is Cinesite in London who not only delivered stunning visuals for John Carter but also had to deal with converting the film from anamorphic 35mm to digital stereo. Stereo D, another leading company, converted Titanic, while Legend3D worked on Transformers: Dark of the Moon. There are several leading companies in this area today such as Prime Focus, who after a battering of critical opinion on the conversion of Clash of the Titans, recently converted Star Wars Episode 1 and the new Wrath of the Titans. For example, the opening macro eyeball shot was far too close for a stereo camera rig to film, and this first shot of the film was converted stereo from 2D. Even Avatar required tiny amounts of stereo conversion. For everything else live-action, normal stereo production is hard. Image from Tangled.ģD animated films, such as Toy Story 3, Up, Brave, Tangled and others find it easy to correctly generate stereo imagery from either stereo renders such as RenderMan or just rendering the entire scene from two similar but offset virtual cameras. Below his comments are included as part of our special case studies on major feature films.
John Knoll (ILM) oversaw the stereo conversion of the Star Wars films for director George Lucas starting with Star Wars – Episode One: The Phantom Menace and you can watch our detailed chat with John on that process here. Stereo conversion is also needed for converting older films – such as Top Gun or the Star Wars franchise.
Thus, even on films shot in stereo, there may well be a need to convert some footage and that high-quality conversion is an important tool in the box of any effects house. Even on a stereo film, lenses and situations oftentimes render a single camera the only viable solution. Yet many filmmakers do not want the physical size of an onset stereo rig, or they prefer to shoot film (ruling out stereo in-camera, effectively) or want to use anamorphic lenses which are extremely difficult for stereo native capture. Many people argue that if you want a film in stereo you should shoot it in stereo.
#2D TO 3D CONVERSION PLUS#
We originally published an Art of Stereo conversion two years ago, and this is a new updated version of that story covering The Avengers, Titanic, John Carter, Star Wars: Episode I, plus the newest techniques and approaches. Stereo conversion, or dimensionalization as it is sometimes called, is the process of making stereo images from non-stereo traditional 2D images.
