Avatar: Fire and Ash brings back James Cameron’s clever trick with frame rates, just like he did in The Way of Water. Some scenes run at a super smooth 48 frames per second, while others stick to the classic 24 frames per second. This mix creates a unique look that matches the action on screen.
In Fire and Ash, the high frame rate scenes shine during fast-moving moments like flying or underwater parts. These hit 48 FPS to make motion feel incredibly real and fluid, especially in 3D. For example, check out this video explanation on why Cameron mixes 24 vs 48 FPS in his Avatar movies: https://www.youtube.com/watch?v=k9fra3bVkW8. It shows how 48 FPS helps in action sequences for a stronger sense of being there, cutting down on that weird “brain strain” from 3D effects.
Dialogue scenes and calmer parts stay at 24 FPS, the standard for movies. This keeps the traditional film feel, with a bit of that dreamy motion blur people love in cinema. Viewers might notice the switch because our eyes pick up between 30 and 60 FPS, as noted in discussions around the film. One report explains how some Fire and Ash scenes look extra smooth on purpose: https://entertainment.slashdot.org/story/25/12/22/1927237/why-some-avatar-fire-and-ash-scenes-look-so-smooth-and-others-dont.
Cameron’s goal is to boost the 3D experience without losing the movie magic. Higher rates smooth out jumping edges that tire your brain in 3D. He shot many parts in 3D at 48 FPS from the start, similar to Way of Water. Critics had mixed views, but Cameron pointed to the $2.3 billion box office win for Way of Water as proof it works.

This approach lets fiery action pop with clarity, while water-like flows or talks feel more natural at lower rates. Fans who saw it in high frame rate 3D formats spotted the shifts right away.
