# Historical Story Video (30s) ## When to use - The user wants a ~30-second vertical (9:16) documentary-style video telling a historical story, with spoken narration (voiceover) in a language they choose. - The user wants the story either from their own input OR from factual information gathered via web search (so the info is valid). - The user wants to revise one stage of an existing video from this skill (change the story/script, regenerate a scene image or clip, change the narration language, change the music, generate a thumbnail, or re-mix the final video). ## Steps ### 1. Gather input (ask only what's missing) Ask the user for (if not already given): - **Topic / era / person** of the historical story. - **Narration language** (e.g. Indonesian, English, Malay, etc.). - **Source**: (a) they provide their own story text, or (b) use web search to gather valid facts. - Optional: preferred visual mood (e.g. ancient, war, royal, industrial). ### 2. Gather the story content - If the user chose **web search** (or gave no story): call `search_web` with the topic to collect accurate, factual historical details (dates, places, key figures, events). Use the returned facts as the basis. - If the user provided **their own story**: use their text directly. - Keep the content focused enough to fit a ~30-second narration. ### 3. Write the narration script Write a short documentary-style narration script (~70–80 words, roughly 30 seconds at a calm narrator pace) **in the chosen language**. Tone: factual, cinematic, engaging. Structure: hook → key facts → closing line. Save it with `create_document` (name="Narration Script", entity_type="scripts") so the user can review/edit it. If the user edits it, use `update_document` on the same asset. ### 4. Generate the narration (voiceover) Call `generate_tts` with `model='tts.design'`, `text` = the narration script, and a `voice_instruction` describing a calm, clear documentary narrator voice (e.g. "deep, calm, clear documentary narrator, neutral accent"). The speech will be produced in the language of the script. Name="Narration Audio", entity_type="voiceover". ### 5. Generate scene images (documentary style) Generate **3 vertical (9:16) documentary-style images** that illustrate the story (e.g. period-appropriate scenes, key moments, figures). Use `generate_image` with `model='t2i'`, `orientation='portrait'`, `resolution='720P'`, and a detailed prompt describing each scene in a realistic, cinematic documentary style. Name them "Scene 1", "Scene 2", "Scene 3" (entity_type="storyboard_images"). ### 6. Generate video clips from the images For each scene image, call `generate_video` with `model='i2v'`, `input_urls=[scene_image]`, `orientation='portrait'`, `duration=10` (3 clips × 10s ≈ 30s). Prompt each clip with a subtle cinematic motion (slow pan, zoom, drifting smoke, waving flag, etc.) matching the scene. Name them "Clip 1", "Clip 2", "Clip 3" (entity_type="storyboard_videos"). ### 7. Generate background music Call `generate_music` with a prompt for a subtle, atmospheric documentary score (e.g. "soft, cinematic, historical documentary background music, low strings and piano, calm and evocative"). Name="Background Music", entity_type="music". ### 8. Mix the final video Call `mix_clips` to assemble the final ~30s vertical video: - `clips`: one clip config that concatenates Clip 1 → Clip 2 → Clip 3 (use `videos` list in order). - Add the narration audio track (`audio` = Narration Audio) and the music track (`audios` = Background Music, low volume ~0.3). - `orientation='portrait'` (9:16). Name="Final Video", entity_type="final_videos". ### 9. Generate a thumbnail (cover image) Generate a striking vertical (9:16) documentary-style thumbnail/cover image that represents the story (e.g. the most iconic scene or figure, cinematic lighting, title-worthy composition). Use `generate_image` with `model='t2i'`, `orientation='portrait'`, `resolution='720P'`. Name="Thumbnail", entity_type="storyboard_
