H3-World Video Tool

Combine a scene description, an optional first frame and an action script to render a world sequence. Preview movements and camera turns before generating the video with its soundtrack.

The default 28-step workflow needs a long GPU allocation and generally requires PRO quota. Shorter Turbo runs use less quota. Previewing an action script is separate from generating video; actions are rendered in a submitted clip.
