History Explainer — a historical event or figure → a cinematic documentary short
A finished reel = vertical 9:16 + voiceover + music + ~45–90s. Pass `aspect_ratio: "9:16"` to `generate_project` (it now threads to every scene), set the i2v `duration` to 8–15s on EVERY scene and animate all of them (default ~5s + skipped scenes = the "38s instead of 90s" bug), add `inworld-tts` narration (not the chatterbox default voice) + `music`, and mux the bed with `audio_fill:"loop"` so the score covers the whole reel (not just the first part). A silent landscape montage — or one whose music cuts out two-thirds in — is a draft, not a deliverable. See the `short-form-video` skill's *definition of done*.
