Spatiotemporal Consistency

What is spatiotemporal consistency, and why are AI-generated hands so mangled? In video generation, this consistency acts as a vital stabilizer, forcing the AI to maintain uniform shapes across consecutive frames and naturally smoothing out errors. Single-image AIs completely lack this temporal alignment, which is exactly why static fingers so often look warped or deformed.

This phenomenon frequently occurs in Midjourney. Just check out the highlighted before-and-after examples above to see the difference after editing in Nano Banana Pro. Paradoxically, while video is much more complex and computationally demanding, that extra data is actually the cure; the sheer necessity of frame-to-frame logic forces the AI to generate more structurally consistent hands than it ever could in a single, isolated imag
