What do the movies MX and IMAX refer to respectively? Does it mean the same thing?

The IMAX screen is indeed large, but not only the screen is large, but also the sound effect and resolution are high, which is 4K resolution.

Let's talk about the difference between IMAX and 3D movies.

If the film advertises itself as an IMAX film, it means that it was shot with an IMAX camera, which is a way of shooting 3D movies.

But not all 3D movies are IMAX, and many are converted to 3D later. Clash of the titans is a typical example, and the converted 3D effect is very poor.

If the cinema says that the film is IMAX3D, it will be shown in IMAX Hall, indicating the difference of projection equipment.

There are shutter 3D, dual-camera 3D, Reald3D and so on.

The best effect is definitely the IMAX hall.

But IMAX also has 2D, and the upcoming "Mission Impossible 4" is IMAX2D, but the effect is definitely better than ordinary movies. The difference is equivalent to looking at the difference between ordinary 480P REVB and the whole picture of1080 p p.
