The use of 3D for any production needs to be based on informed and intelligent decisions about whether the production really needs that extra dimension and not just because it is available, said the experts at the Monte-Carlo TV Festival.

Speaking at the 'TVXchanges' conference, Franck Savorgnan, Line Producer S-3D said: “Every producer considering taking on the added expense and technical complications of 3D first must ask themselves why there are thinking about using it."

Savorgnan added that everyone, both professionals and the audiences, needed to be aware that there is so much potential for conflict in terms of the scale of the images and the size of the screen. To explain this he put the following example: “[DVDs] of fish in an aquarium have been successful for the same basic reason, that a fish tank and a TV are very similar in size so there is no conflict of space and depth".

On the other hand Pascale Charpentier, Motion Designer S-3D, took a deeper look at this subject by stating that there are limitations on the rapid edits and also on camera movements, which here are critical because " there really is a limit to how quickly viewers are able to perceive the 3D illusion" he underlined. “Basically it sets up a conflict in the brain about whether to take into account the object or the space around the object," he explained.

Finally Stewart Dickinson of Sony DADC assured that what it has been working “very well" is music content. Definitely it is a growing market, as the horror films, and experimental projects like the 3D fish tank are also doing very well".

Here the same company that did the fish tank video is also currently working on a project using stereoscopic still images of several big cities in the 19th century that are being animated on a Rotoscope to create live 3D images.
