How are 3D movie pictures made?

To put it simply, there are two ways to make 3D movie pictures, one is to shoot directly with a dual-lens camera, and the other is to shoot 2D in the early stage and transform it later. Or through the cooperation of two production methods.

Dual-lens shooting is to use dual cameras and dual-lens 3D shooting equipment to record synchronously in the early stage of shooting, and then process the two materials respectively. Finally, in the 3D cinema, two videos are transmitted to people's left and right eyes by using 3D display technology, that is, red and blue display, polarization display and active shutter display, so as to obtain stereoscopic images. The 3D version of Reconnection 4 is based on this technology.

The other is to shoot a 2D movie and turn it into a 3D movie. 20 12 On April 4th, the 3D version of Titanic was re-released, with a global box office of 344 million US dollars, and the total box office became 265,438+87 million US dollars. It is reported that the transition from a 2D film to a 3D version of Titanic is costly, and it took more than 300 technicians 60 weeks to complete the production, with a cost as high as 654.38+08 million US dollars, while the total investment of the expensive 2D version is only 200 million US dollars. Judging from the current movie market, a 2D blockbuster needs a professional team and professional software to become 3D, requires strong professional skills, and the production cost should start at least 2 million US dollars. For ordinary producers, the cost of making a successful 3D movie is very high, and the investment risk will increase. Many producers are afraid to get involved.
