Vance IngallsandClaude Opus 5 75057e2807 feat(core): expose the AudioParams behind automatable FX knobs
Marks the knobs an automation lane can drive and has each graph builder hand
back the AudioParam behind them, so a scheduler can write to a running effect
without knowing what the effect is.

A knob is not always one AudioParam. A wet/dry mix is two gains moving in
opposition, and a knob in milliseconds drives a delay time in seconds, so
each target carries the mapping out of the knob's own declared unit.

What stays unautomatable is stated where it is decided: a WaveShaper curve, a
convolution impulse and a one-pole filter's coefficients are all rebuilt
wholesale rather than scheduled, and the four worklet effects take values by
postMessage rather than through AudioParams.

The registry flag is written by hand, so a test builds every effect and
checks the exposure both ways — nothing flagged is missing, nothing exposed
is unflagged. A flag that lied would offer a lane that silently did nothing.

@hyperframes/core

Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.

Install

npm install @hyperframes/core

Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.

What's inside

Module Description
Types TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults
Parsers parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations
Generators generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec
Compiler compileTimingAttrs — resolve data-start / data-duration into absolute times
Linter lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.)
Runtime IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol
Frame Adapters Pluggable animation drivers (GSAP, Lottie, CSS, or custom)

Frame Adapters

A frame adapter tells the engine how to seek your animation to a specific frame:

import { createGSAPFrameAdapter } from "@hyperframes/core";

const adapter = createGSAPFrameAdapter({
  getTimeline: () => gsap.timeline(),
  compositionId: "my-video",
});

Implement FrameAdapter for custom animation runtimes:

import type { FrameAdapter } from "@hyperframes/core";

const myAdapter: FrameAdapter = {
  id: "my-adapter",
  getDurationFrames: () => 300,
  seekFrame: (frame) => {
    /* seek your animation */
  },
};

Parsing and generating HTML

import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";

const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);

Linting

import { lintHyperframeHtml } from "@hyperframes/core/lint";

const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
