Asset preprocessing for HyperFrames compositions — multi-provider TTS (HeyGen / ElevenLabs / Kokoro local), multi-provider BGM (Google Lyria / local MusicGen), Whisper transcription, background removal, and caption authoring. Use for npx hyperframes tts, bgm, transcribe, remove-background, voice/provider selection, music-mood prompting, captions / subtitles / lyrics / karaoke / per-word styling.

HyperFrames Media

CLI commands that create assets (tts, bgm, transcribe, remove-background), plus everything needed to consume and animate transcript data in HTML. For placing assets into compositions, see hyperframes-core.

Provider chains (auto-detected from env)

TTS — npx hyperframes tts "..." picks the first available provider:

Order	Provider	Detected when	Word timestamps
1	HeyGen (Starfish)	`$HEYGEN_API_KEY` / `hyperframes auth login`	Yes, native — pass `--words narration.words.json` to capture
2	ElevenLabs	`$ELEVENLABS_API_KEY` set	No — chain `transcribe` after
3	Kokoro-82M (local, 54 voices)	always (no key required)	No — chain `transcribe` after

If the installed hyperframes tts is the local-only build (its --help says "Kokoro-82M" and has no --provider/--words flags), it silently falls back to Kokoro even with $HEYGEN_API_KEY set. To force HeyGen regardless of CLI version, use the self-contained scripts/heygen-tts.mjs (see references/tts.md).

BGM — npx hyperframes bgm --duration N:

Order	Provider	Detected when
1	Google Lyria (RealTime)	`$GEMINI_API_KEY` or `$GOOGLE_API_KEY` set
2	MusicGen (`facebook/musicgen-small`, local)	Python `transformers + torch + soundfile` installed

Override either with --provider <name>.

Non-negotiable rules

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. When you want captions, either pass --words to HeyGen and use that JSON directly, or run transcribe against the audio file. Don't assume word data is always there.
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".
