hyperframes

HTML video production with synchronized captions and TTS narration is automated by translating user prompts into deterministic HyperFrames video compositions. These compositions feature data-driven timelines, audio-reactive visuals, and per-scene choreography to deliver repeatable multi-scene renders.

Generating multi-scene video explainers from a single text prompt is fully supported. The system translates the prompt into a complete production-ready composition, applying beat-driven motion, marker highlights, and shader or CSS transitions across all scenes for repeatable outputs.

Deterministic rendering for HTML-based video compositions works by using data-driven timelines and per-scene choreography to guarantee repeatable outputs across environments. This ensures that complex animation, text-to-speech timing, and audio-reactive visuals render consistently every time.

The @hyperframes/producer package is required as a dependency to render cinematic videos. It provides the underlying environment needed to process the generated HTML compositions, ensuring deterministic rendering and proper synchronization of audio-reactive visuals.

The best way to add audio-reactive visuals and scene transitions is by defining per-scene prompts within a HyperFrames composition. The system handles the choreography, applying shader and CSS transitions alongside beat-driven motion synchronized to audio timing.

Multi-scene video rendering relying on GSAP timelines requires strict synchronization with TTS narration and audio-reactive visuals to maintain deterministic outputs. Complex shader or CSS transitions may increase render overhead, so scene choreography must be carefully structured to avoid timing desynchronization.
