What it does

Hyperframes Media is an agent skill from chmonitor/chmonitor. Audio and media assets for HyperFrames compositions, produced by one shared audio engine (scripts/audio.mjs) — multi-provider TTS (HeyGen / ElevenLabs / Kokoro local), background music + sound effects (HeyGen audio-library retrieval by default, with local Lyria / MusicGen BGM generation and a bundled SFX library as the no-credential fallback), Whisper transcription, background removal, and caption authoring. Use for voiceover / TTS, BGM, SFX / sound effects, transcription, captions / subtitles / lyrics / karaoke…

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 26 other files, including scripts, reference files and assets (for example `assets/sfx/CREDITS.md`, `assets/sfx/manifest.json` and `references/bgm.md`).

It sits in Media & Creative, covering Text to speech and voice, Transcription and Motion graphics. It works with HeyGen and ElevenLabs. The repository describes itself as: Open-source operational advisor for ClickHouse — real-time monitoring plus AI-driven index/partition/materialized-view recommendations. The licence is GPL-3.0.

When your agent uses it

  • Voiceover / TTS
  • SFX / sound effects
  • Captions / subtitles / lyrics / karaoke / per-word styling
  • Voice + provider selection

Example prompts

  • “/hyperframes-media”

Requirements

  • Node.js
  • A credential in HEYGEN_API_KEY
  • A credential in HYPERFRAMES_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit fc39ef0. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (JavaScript, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • npx
    • node

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • HEYGEN_API_KEY
    • HYPERFRAMES_API_KEY
    • ELEVENLABS_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hyperframes Media loads about 2.8k tokens when it runs, and up to ~16k if it reads all its reference files. Until then it costs about 153 tokens; SKILL.md has 1,119 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~153
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~16k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

description
Audio and media assets for HyperFrames compositions, produced by one shared audio engine (`scripts/audio.mjs`) — multi-provider TTS (HeyGen / ElevenLabs / Kokoro local), background music + sound effects (HeyGen audio-library retrieval by default, with local Lyria / MusicGen BGM generation and a bundled SFX library as the no-credential fallback), Whisper transcription, background removal, and caption authoring. Use for voiceover / TTS, BGM, SFX / sound effects, transcription, captions / subtitles / lyrics / karaoke / per-word styling, voice + provider selection, and music-mood prompting.

HyperFrames Media

Create the audio and media assets a composition needs — voiceover (TTS), background music + sound effects, transcription, captions, background removal — then consume and animate that data in HTML. For placing assets into compositions, see hyperframes-core.

The audio engine — one source for TTS · BGM · SFX

Workflows do NOT hand-roll audio or vendor a copy. There is one engine — scripts/audio.mjs — that takes a neutral audio_request.json and writes audio_meta.json (plus assets under assets/voice|bgm|sfx):

bash
# <MEDIA_DIR> = this skill's directory
node <MEDIA_DIR>/scripts/audio.mjs --request ./audio_request.json --hyperframes . --out ./audio_meta.json

All three capabilities degrade on ONE switch — whether a HeyGen credential is present (resolved from $HEYGEN_API_KEY / $HYPERFRAMES_API_KEY / ~/.heygen, not the CLI):

CapabilityHeyGen credential presentabsent
TTSHeyGen Starfish REST (native word timestamps)→ ElevenLabs → Kokoro (chain transcribe for words)
BGMHeyGen music retrievalLyria → MusicGen local generation (detached)
SFXHeyGen sound-effects retrieval (min_score 0.4)bundled 21-file library (assets/sfx/)
  • Request (audio_request.json): { provider?, lang?, speed?, lines: [{ id, text, sfx?: [names] }], bgm: { mode?, query?, prompt? } }. id joins each line back to the caller's model (a frame number, a scene id, …). bgm.mode = retrieve | generate | none; omit for auto (retrieve when credentialed, else generate). An explicit retrieve is strict — it skips rather than starting a detached generate (for callers with no wait-bgm step).
  • Output (audio_meta.json, id-keyed): { tts_provider, voice_id, bgm, bgm_pending, …, voices: [{ id, path, duration_s, words }], sfx: [{ id, name, file, source, offset_s, duration_s, volume }], total_duration_s }.
  • --only tts,bgm,sfx runs a subset and merges into an existing --out (e.g. TTS+BGM early, SFX once cues exist).
  • BGM generate is spawned detached (bgm_pending: true) — run scripts/wait-bgm.mjs before assembling.
  • scripts/heygen-tts.mjs is a single-shot CLI over the same code (one text → wav + words) for when you just need HeyGen TTS without a request file.

Full flag list + the audio_meta.json schema live in the header of scripts/audio.mjs. The references below cover the provider details and edge cases behind each capability.

Preflight — show sign-in status before any audio

Always run this before generating voice or BGM — inside a full workflow or a one-off "generate me a BGM/voiceover" request. No HeyGen credential is not a reason to silently fall back to local engines: first recommend signing in and let the user decide. Run the shared preflight and relay its output verbatim — don't improvise your own "missing key" prompt, and don't offer to write keys into a per-repo .env:

bash
npx hyperframes auth status
  • Signed in → it prints the account; proceed.
  • Not signed in (exit 1 is expected here — "not signed in" is a normal state, not a failure) → it prints registration-first guidance. Recommend signing in: npx hyperframes auth login is browser OAuth — it signs in and creates an account (always available through this repo's CLI). To use an existing HeyGen API key (from app.heygen.com/settings/api), run npx hyperframes auth login --api-key — it saves to the shared ~/.heygen (no per-repo .env). The output also lists the local engines voice/BGM will fall back to and a pip hint when deps are missing. Relay this output as-is — don't paraphrase it into your own wording. Then STOP and wait for the user to choose — sign in, or say "go" / "local" to continue offline — before generating anything. This is a real decision point, not a passing note: don't fold it into another question, and don't proceed past it on your own. (Exception: in autonomous / non-interactive mode, note the status and continue offline.)
  • npx hyperframes auth status --json returns { configured, recommended_action, offline_engines } for deterministic branching.
  • If the CLI can't run (not on PATH and npx can't fetch it) → still recommend signing in (npx hyperframes auth login) and STOP for the user's choice — don't treat "no credential" as a silent green light for local generation.

Credential resolution, full key priority, and the local-dependency list are in references/requirements.md.

Provider chains (the detail behind the engine)

TTS — first available provider wins (the engine, or npx hyperframes tts "..."):

OrderProviderDetected whenWord timestamps
1HeyGen (Starfish)$HEYGEN_API_KEY / hyperframes auth loginYes, native — pass --words narration.words.json to capture
2ElevenLabs$ELEVENLABS_API_KEY setNo — chain transcribe after
3Kokoro-82M (local, 54 voices)always (no key required)No — chain transcribe after

The published hyperframes tts CLI is often the local-only build (its --help says "Kokoro-82M", no --provider/--words) and silently falls back to Kokoro even with $HEYGEN_API_KEY set. That is why the engine's HeyGen path is the self-contained scripts/heygen-tts.mjs (REST), NOT the CLI; the CLI is used only for the Kokoro path. See references/tts.md.

BGM & SFX — by default retrieved from the HeyGen audio library (/v3/audio/sounds), same credential as HeyGen TTS, with the no-credential fallback from the switch above:

AssetHeyGen typeLands inFallback (no credential)
BGMmusicassets/bgm/track.mp3 (retrieve) · track.wav (generate)Lyria / MusicGen generation
SFXsound_effects (min_score 0.4)assets/sfx/<slug>.mp3bundled 21-file library (assets/sfx/* + manifest.json)

Non-negotiable rules

  • One engine, no vendored copies. Produce audio via scripts/audio.mjs (or heygen-tts.mjs for one-shot HeyGen TTS). Don't re-implement TTS/BGM/SFX inside a workflow — write an audio_request.json adapter and call the engine.
  • "HeyGen available" = a resolvable credential, not the CLI. The whole switch keys off heygenCredential(); the published hyperframes tts may be Kokoro-only, and there is no hyperframes bgm / hyperframes sfx command at all.
  • Voice IDs are provider-specific. am_michael is Kokoro-only; HeyGen UUIDs don't work on Kokoro. If you pass --voice, also pin --provider to avoid silent provider drift when the user's env changes.
  • Always pass --model to transcribe. The CLI default small.en silently translates non-English audio. See references/transcribe.md → "Language Rule".
  • HeyGen returns word timestamps; ElevenLabs / Kokoro do not. The engine chains transcribe automatically for the latter two; standalone, pass --words to HeyGen or run transcribe against the audio file.
  • Captions consume the flat word-array format with { id, text, start, end }. See references/transcribe.md → "Output Shape".
  • remove-background --background-output is hole-cut, not inpainted. For "scene without the person", a different tool is needed. See references/remove-background.md → "When NOT the right tool".
  • BGM/SFX default to HeyGen retrieval; the no-credential fallback is generation (BGM) or the bundled library (SFX). /audio/sounds ranks by a text query — name effects concretely (glass shatter, not dramatic sound); a no-match skips, never blocks the render. SFX sit at volume ~0.35 under voice + BGM. See references/sfx.md / references/bgm.md.
  • Treat workflow caption HTML as generated output. For preset-backed videos, the reusable skin source lives at .hyperframes/caption-skin.html and the workflow script writes compositions/captions.html; do not edit generated compositions/captions.html to fix the skin. Rebuild via the workflow's captions.mjs, or use that workflow's explicit overrides mechanism when present.

Can I use Hyperframes Media in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add chmonitor/chmonitor --skill hyperframes-media -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/hyperframes-media, .gemini/skills/hyperframes-media, .github/skills/hyperframes-media and .opencode/skills/hyperframes-media in your project.

What does Hyperframes Media need to run?

Going by SKILL.md and its folder, Hyperframes Media needs JavaScript for the scripts in its folder, the command-line tools its instructions call (npx and node) and credentials named HEYGEN_API_KEY, HYPERFRAMES_API_KEY and ELEVENLABS_API_KEY. Our summary lists: Node.js; A credential in HEYGEN_API_KEY; A credential in HYPERFRAMES_API_KEY.

Does Hyperframes Media access the network?

SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Hyperframes Media safe to install?

Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Hyperframes Media use?

Hyperframes Media is published under the GPL-3.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Hyperframes Media use?

About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 14k tokens, read only when the agent opens those files.

What are the alternatives to Hyperframes Media?

Skills that share tags, products or a category with Hyperframes Media: Hyperframes CLI (nateherkai/hyperframes-student-kit, 1.2k stars), Qiaomu Cut (joeseesun/qiaomu-cut-skill, 369 stars), Super Video Maker (Bomx/super-video-maker-skill, 305 stars) and Showtime (FavioVazquez/showtime, 158 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Hyperframes Media?

chmonitor (a GitHub organization) maintains it in chmonitor/chmonitor, which has 298 GitHub stars. The repository holds 53 skills in this directory. The repository was last updated on October 5, 2026.
