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 5.1 | $0.00131 | $0.02622 |
| Opus 5.5 | $0.00052 | $0.01049 |
| Sonnet 5.5 | $0.00026 | $0.00524 |
| Haiku 4.5 | $0.00013 | $0.00262 |
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 2mo ago.
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.
This is a copy
100% identical to hyperframes-media — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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? } }.idjoins 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 explicitretrieveis strict — it skips rather than starting a detached generate (for callers with nowait-bgmstep). - 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,sfxruns 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) — runscripts/wait-bgm.mjsbefore assembling. scripts/heygen-tts.mjsis a single-shot CLI over the same code (one text → wav + words) for when you just need HeyGen TTS without a request file.

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.
