Solar

A Remotion + Three.js animation of a stylized 3D solar system with configurable TTS narration in English, Chinese, Japanese, and Korean.

Scripts

npm install
npm run start
npm run voiceover
npm run voiceover:edge
npm run voiceover:gcp
npm run render

The main compositions are SolarSystemEN, SolarSystemZH, SolarSystemJA, and SolarSystemKO. npm run render renders all four MP4 files into out/. The narration sources are public/voiceover/narration.{lang}.txt; npm run voiceover regenerates the ignored MP3 files used by the compositions. The default TTS source, voices, and GCP key location are configured in voiceover.config.json. Use npm run voiceover:edge for Edge TTS or npm run voiceover:gcp for Google Cloud Text-to-Speech. The GCP provider reads GOOGLE_TTS_API_KEY first, then google-tts.key.

See workflow.md for the full build, narration, validation, and render workflow.
