Except it's not.
It's not "shaky cam." There's an operator holding a camera on his shoulder just outside the frame. The camera isn't "Shaking" It's moving slightly, yes, because human beings are not tripods (some dudes, maybe) but it's not juddering, bouncing, or twitching. There's no shaking going on.
Someone is standing there and holding a camera.
The VFX shots had zoom and some jostling added during the action sequences as a means to make it cohesive with the hand-held nature of the cinematography in the non-action scenes. The whole thing has a cohesive visual tone, for the most part.
Shaky camera,[1] shaky cam,[2] hand-held camera or free camera[3] is a cinematographic technique where stable-image techniques are purposely dispensed with. The camera is held in the hand, or given the appearance of being hand-held, and in many cases shots are limited to what one photographer could have accomplished with one camera. Shaky cam is often employed to give a film sequence an ad-hoc, electronic news-gathering, or documentary film feel. It suggests unprepared, unrehearsed filming of reality, and can provide a sense of dynamics, immersion, instability or nervousness.
It's still shakycam and those scenes should have been shot with a stabilizer or something because it was really distracting to me. Maybe the fact that I watched the film on an Imax screen magnified the effect, but it was absolutely jittery and bouncy.
