Pika H3 test: fast and decent, until zoom-out turns goblins into ice skaters

AxonkaiLab · reddit · 2026-11-06

A Reddit user tested Pika H3 video generation in ComfyUI: a MOSS-generated image as the first frame at 1MP (768x1376), then upscaled with SeedVR2.

Verdict is two-sided: Pika is fast and actually not bad, but physics fall apart when the camera zooms out—the floor gets spammed with dead goblins while the rest start ice skating on the tiles. A good speed-first workflow with hilarious physics. The post links to ComfyUI's official Pika H3 Flex workflow for reproduction.
