What's the difference in cost between 2D movies and 3D movies?

From the perspective of pure cost, the cost of 3D movies is definitely higher than that of 2D versions. There are two ways to obtain 3D images, one is to shoot directly with a dual-lens camera (I heard that there is a single-lens scheme recently, but I don't know much about it), and the other is to shoot 2D in the early stage and transform it later.

I don't know much about penhold. In fact, at present, there are not many photographers who can skillfully use dual-lens shooting in China. 3D shooting still depends on an empirical parameter to a great extent, so there is a certain possibility of virtual focus compared with 2D shooting. This situation usually occurs in fast moving, explosion, flying cars and so on. As far as the current technology is concerned, there is no better solution to this focusing problem. Then, compared with 2D real shooting, the main cost increases are equipment (dual lens vs single lens), personnel (3d shooting is more expensive) and the number of shots (more waste lenses).

As a film industry that always stands at the forefront of technology, how can it easily compromise and silently endure such a direct cost increase? Therefore, many doctors of computer graphics in the company later developed a series of software, and made 3d production through software. I answered another question about the post-production process. The main cost lies in the increase of software, hardware and manpower.

If you shoot directly with a 3D camera: First of all, a dual-lens camera is more expensive, with more equipment such as supporting lenses, higher use cost, heavier camera, inconvenient movement and higher requirements for studio operation. Of course, the current digital technology avoids the increase in the cost of double films, but doubling the storage capacity is also the cost of post-production, such as double data for special effects processing, which increases the cost.

Switching to 3D means paying a professional company to switch after filming. A two-hour movie costs about $20 million.
