Mechanism

When It Triggers · How It Works · What It Produces

Breaks down how the skill works and what it produces, so you can quickly judge whether it fits your scenario and value.

Trigger

When a user has a talking-head / interview / podcast video and wants styled, embedded captions (rail subtitles + behind-subject embed peaks), not plain subtitles or graphic overlays.

Mechanism

  • Run npx hyperframes skills update embedded-captions to refresh.
  • Decision gate probes clip via ffprobe/ffmpeg; refuses bad clips.
  • Pick ONE identity from CATALOG.md (36 options).
  • hyperframes init + bash scripts/prepare.sh (matte, transcribe, envelope, safe-zones).
  • Author JSON (plan.json/theme.json) → compile via make-composition.cjs / make-theme.cjs.
  • Visual QA via preview-frames.cjs; render with render-and-composite.sh.

Result

A final.mp4 with untouched footage plus deterministic rail captions and matte-occluded embed peaks, themed per identity.

Use Cases

Two Typical Use Cases

Scenario 01

Explainer video caption styling

A YouTuber has a 10-minute explainer talking-head video and wants professional captions where most words show as a clean lower-third rail and the key punchline appears as a big word behind them. Using this skill, they pick a Standard identity from CATALOG.md, run prepare.sh and the compiler, then get final.mp4 with readable captions and one earned embed peak — boosting retention without reshooting.

Scenario 02

Cinematic VFX caption theme

A studio needs a VFX-grade cinematic caption treatment for a hero interview clip — every caption composited behind the subject with occlusion. They choose a Theme identity (e.g. neonsign), author theme.json, run render-theme.sh to get final_fx.mp4 with plate reaction. The skill delivers an AE-like embedded typography piece without touching the source footage.
