Summary

HTML-based video composition with animations, captions, audio-reactive visuals, and scene transitions.

  • Build video content as HTML with GSAP timelines and data-* attributes for timing; the framework handles clip visibility, media sync, and playback
  • Create captions synced to audio, text-to-speech narration, audio-reactive animations (beat sync, glow, pulse), and animated text effects (marker sweeps, hand-drawn circles, scribbles)
  • Add scene transitions (crossfades, wipes, reveals, shader transitions) between multi-scene compositions; every scene requires entrance animations and transitions between scenes
  • Use variables to parametrize compositions — render the same source with different titles, colors, or content without editing HTML
  • Supports sub-compositions loaded via external HTML files, design systems via design.md, and deterministic, fully seekable animations with no random or time-based logic

HyperFrames

HTML is the source of truth for video. A composition is an HTML file with data-* attributes for timing, a GSAP timeline for animation, and CSS for appearance. The framework handles clip visibility, media playback, and timeline sync.

Approach

Discovery (exploratory requests only)

For open-ended requests ("make me a product launch video", "create something for our brand") where the user hasn't committed to a direction, understand intent before picking colors:

  • Audience — who watches this? Developers? Executives? General consumers?
  • Platform — where does it play? Social (15s), website hero, product demo, internal?
  • Priority — what matters most? Motion quality? Content accuracy? Brand fidelity? Speed?
  • Variations — does the user want options, or a single best shot?

For specific requests ("add a title card", "fix the timing on scene 3"), skip discovery.

For exploratory requests, consider offering 2-3 variations that differ meaningfully — not just color swaps, but different pacing, energy levels, or structural approaches. One safe/expected, one ambitious. Don't mandate this — it's a tool available when appropriate.
