It's fascinating comparing the animation in Gundams Zeta and ZZ. I know I've said this before on @GundamPodcast but it bears repeating that while Zeta often looks more impressive in stills, it relies more on limited animation tricks and reused footage. ZZ is looser. https://twitter.com/GundamPodcast/status/1342856476440879112

One consequence of this is that ZZ uses impact frames more sparingly than Zeta did. Impact frames make individual moments land more powerfully but at the same time they interrupt the flow. I think this is part of why Zeta feels 'weightier' than ZZ.

Instead, ZZ makes liberal use of an animation technique that appeared rarely (if ever!) in Zeta: the exaggerated squash and stretch. No doubt some of this comes down to the preferences of individual animators or directors, but it also fits the show's comedic tone.

Ditto these, which I am informed are called smears and which I can't remember ever spotting in Zeta:

ZZ also demonstrates one of animation's greatest strengths in how it uses body movement to convey information about its characters. Bright, uncomfortable in his role as captain, can't sit properly in his chair.

Uncertain about the AEUG and missing his family, he keeps subconsciously fiddling with the uniform collar that is suffocating him.

Where Judau, an awkward teenager despite his posturing, is often gangly and bowlegged when he runs, preening aristocrat Glemy springs like a ballet dancer.

I'm not sure if these are intentional, but when Bright talks to Wong Lee he's drawn looking younger than normal - perhaps as a way to emphasize his junior role. Similarly, Judau is made to look older when he tries to exert his brotherly authority over Leina.
