Allocation of 'depth budget' РІР‚вЂњ defining the range of permitted disparity or depth, what depth value corresponds to the screen position (so-called 'convergence point' position), the permitted distance ranges for out-of-the-screen effects and behind-the-screen background objects.Without respect to particular algorithms, all conversion workflows should solve the following tasks:

Besides the mentioned hard-to-shoot scenes, there are situations when mismatches in stereo views are too big to adjust, and it is simpler to perform 2D to stereo conversion, treating one of the views as the original 2D source. However, while the zoom lens would provide acceptable image quality, the stereo separation would be virtually nil over such a distance.Р”В®ven in the case of stereo shooting, conversion can frequently be necessary. For example, the simplest way to film a scene set on the side of a building might be to use a camera rig from across the street on a neighboring building, using a zoom lens. By their very nature, stereo cameras have restrictions on how far the camera can be from the filmed subject and still provide acceptable stereo separation.The same scene filmed in stereo would reveal that the actors were not the same distance from the camera. For example, some scenes in the Lord of the Rings film trilogy were filmed using forced perspective to allow two actors to appear to be different physical sizes. Stereo cameras can betray practical effects used during filming.This correction sometimes may have complexity comparable to stereo conversion. Stereo cameras can introduce various mismatches in stereo image (such as vertical parallax, tilt, color shift, reflections and glares in different positions) that should be fixed in post-production anyway because they ruin the 3D effect.Some shots, particularly action scenes, can be only shot with relatively small 2D cameras.

Professional stereoscopic rigs are much more expensive and bulky than customary monocular cameras.

Stereo post-production workflow is much more complex and not as well-established as 2D workflow, requiring more work and rendering.

The reasons for shooting in 2D instead of stereo are financial, technical and sometimes artistic: Even Avatar contains several scenes shot in 2D and converted to stereo in post-production. The majority of non- CGI stereo 3D blockbusters are converted fully or at least partially from 2D footage. With the increase of films released in 3D, 2D to 3D conversion has become more common. However, not all CGI films are re-rendered for the 3D re-release because of the costs, time required, lack of skilled resources or missing computer data. Revisiting the original computer data for the two films took four months, as well as an additional six months to add the 3D. Examples of this technique include the re-release of Toy Story and Toy Story 2. This is technically not a conversion therefore, such re-rendered films have the same quality as films originally produced in stereoscopic 3D. Re-rendering of computer animated films Р”В¬omputer animated 2D films made with 3D models can be re-rendered in stereoscopic 3D by adding a second virtual camera if the original data is still available. Two approaches to stereo conversion can be loosely defined: quality semiautomatic conversion for cinema and high quality 3DTV, and low-quality automatic conversion for cheap 3DTV, VOD and similar applications. If done properly and thoroughly, the conversion produces stereo video of similar quality to 'native' stereo video which is shot in stereo and accurately adjusted and aligned in post-production. However, in order to be successful, the conversion should be done with sufficient accuracy and correctness: the quality of the original 2D images should not deteriorate, and the introduced disparity cue should not contradict other cues used by the brain for depth perception.
