Avatar: Fire and Ash was released in the 4DX format with motion-enabled seats and environmental effects. The presentation extends the film beyond the screen by moving seats in sync with on-screen action and adding physical sensations such as wind, water, vibration, lighting, and other theatrical effects.
4DX is designed to make viewers feel physically involved in a scene. Flight sequences can trigger seat movement and air effects, while storms, explosions, water, and impacts may be represented through motion, sprays, flashes, or atmospheric effects. The exact effects can vary by cinema and local installation.
4DX is not the same as IMAX, which primarily emphasizes a large screen, high image quality, and powerful sound. It is also distinct from ScreenX, which expands selected images onto side walls, and D-Box, whose seats provide programmed motion but generally do not represent the broader environmental-effects package associated with 4DX. Avatar: Fire and Ash was also shown in other premium formats, but the motion-seat-and-effects description specifically identifies 4DX.
