What is hyperframes-media?

A shared workflow for creating audio and media assets for HyperFrames videos. It covers text-to-speech voiceovers, background music, sound effects, transcripts, captions, and removing backgrounds from images or video.

Use it to produce or retrieve narration, music, and sound effects, create transcripts and captions, remove backgrounds, and pass those assets into HTML-based video compositions.

It keeps audio creation and its timing data in one process, so the composition can use the resulting files and word-level information consistently.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5	$0.00131	$0.02622
Opus 5	$0.00066	$0.01311
Sonnet 5	$0.00026	$0.00524
Haiku 4.5	$0.00013	$0.00262

Security

Grade A, and why

hyperframes-media scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

The scan reads SKILL.md. This mod also ships 12 executable files (scripts/audio.mjs, scripts/heygen-tts.mjs, scripts/lib/bgm.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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):

# <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):

Capability	HeyGen credential present	absent
TTS	HeyGen Starfish REST (native word timestamps)	→ ElevenLabs → Kokoro (chain `transcribe` for words)
BGM	HeyGen music retrieval	Lyria → MusicGen local generation (detached)
SFX	HeyGen 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.

What ships with it

24 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

hyperframes-media is a skill published in the GitHub repository maiscafe/video_motion (2 stars, last pushed 1mo ago), licensed MIT. It adds 131 tokens to every session and 2,622 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
