Is there any difference between IMAX film and IMAX digital?

IMAX film refers to the shooting of films, and only IMAX films are shot with a 70mm camera.

This is too expensive and requires special filming, so there are only a few commercial films** such as Batman, The Dark Knight and Transformers.

2 Some clips are made of 70mm film shot with IMAX, and most of the film IMAX format ** are converted from ordinary film for DMR, so even 70mm film is actually equivalent to the resolution of interpolation 6K (of course, film can't be completely calculated like this), which is not much better than the interpolation of digital IMAX of 4K.

The shooting of IMAX films, originally only with a 70mm camera to shoot film IMAX is considered IMAX film, but because the cost is too high and special filming is required, so in commercial films, except for a few** such as Batman, The Dark Knight and Transformers 2 Some clips are filmed with IMAX 70mm film, most of the film IMAX format ** are converted from ordinary film DMR, so even so 70mm film is actually equivalent to an interpolated resolution of 6K (of course, film can't be fully calculated), which is not much better than the interpolation of 4K for digital IMAX.

1. Different categories. The 3D we usually see is from the dimensionality, and IMAX is from the screen size.

2. The effect is different。The effect of the two is completely different, and 3D can only feel the presence of one space. Add IMAX on the basis of 3D, then there will be a large screen and ultra-luxurious visual enjoyment.

3. Different characteristics:IMAX In order to greatly increase the resolution of the image, Cailing used a special 70 mm negative. The image size of a traditional 65 mm film is mm (mm) and the image size of an IMAX film is mm.

In order to make a standard film 24 frames per second, IMAX negatives are fed three times faster than regular negatives.

There is also the Japax system, which has a format area of about 5 times that of the standard 35 mm format and can be projected on a screen with a width of 23 meters and a height of 17 meters. There is also a showscan system that increases the frequency of shooting and projection to 60 frames per second to eliminate flicker and make dynamic scenes clearer.

1. The number of frames is different.

2. The picture is different.

IMAX60 frames Sun Missing Hall: The three-dimensional characters in the movie are more detailed and clearer.

Original imax3D: The three-dimensional characters in the movie are in clear focus, and the three-dimensional spike has a strong sense of lifting.

<>3. The effect is different.

imax60 Frame Hall: More realistic and detailed than imax3D in action graphics.

Original iMAX3D: Produces a realistic full-field stereoscopic effect.

4. The requirements for the cinema hall are different.

IMAX60 Theater: Only 60 fps versions of the movie will be best seen in the 60 fps theater.

Original imax3d: The 60 fps version of the movie does not look best in imax3d.

5. Fluency varies.

imax60 Frame Hall: The action picture is presented more smoothly than imax3D.

Original imax3D: Smooth action graphics.

IMAX stands for Giant Screen Cinema (IMAX, short for Image Maximum) and is a film projection system capable of projecting larger and higher resolution than traditional film.

The complete system includes film copies, projectors, sound systems, screens, etc., which are shot in IMAX specifications. The standard IMAX screen is 22 meters wide and 16 meters high, but it is perfectly possible to use it on larger screens**, and there are still more and more to date.
