# Video zu Musik

POST https://api.elevenlabs.io/v1/music/video-to-music
Content-Type: multipart/form-data

Hintergrundmusik aus einer oder mehreren Videodateien erstellen. Videos werden der Reihe nach kombiniert. Optionale Beschreibungs- und Stil-Tags beeinflussen die generierte Musik.

Reference: https://elevenlabs.io/docs/api-reference/music/video-to-music

## Servers

- `https://api.elevenlabs.io` (Production, default)
- `https://api.us.elevenlabs.io` (Production US)
- `https://api.eu.residency.elevenlabs.io` (Production EU)
- `https://api.in.residency.elevenlabs.io` (Production India)
- `https://api.sg.residency.elevenlabs.io` (Production Singapore)

## Request

### Query parameters

- `output_format` (enum, optional) — Output format of the generated audio. Formatted as codec_sample_rate_bitrate. So an mp3 with 22.05kHz sample rate at 32kbs is represented as mp3_22050_32. MP3 with 192kbps bitrate requires you to be subscribed to Creator tier or above. PCM with 44.1kHz sample rate requires you to be subscribed to Pro tier or above. Note that the μ-law format (sometimes written mu-law, often approximated as u-law) is commonly used for Twilio audio inputs.
  - Allowed values: `mp3_22050_32`, `mp3_24000_48`, `mp3_44100_32`, `mp3_44100_64`, `mp3_44100_96`, `mp3_44100_128`, `mp3_44100_192`, `pcm_8000`, `pcm_16000`, `pcm_22050`, `pcm_24000`, `pcm_32000`, `pcm_44100`, `pcm_48000`, `ulaw_8000`, `alaw_8000`, `opus_48000_32`, `opus_48000_64`, `opus_48000_96`, `opus_48000_128`, `opus_48000_192`
- `enable_logging` (boolean, optional, default: true) — Wenn enable_logging auf false gesetzt ist, wird für die Anfrage der Modus ohne Datenspeicherung verwendet. Dieser Modus steht nur Enterprise-Kunden zur Verfügung.

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `videos` (files, required) — Eine oder mehrere Videodateien, die über ein FormData-Array (multipart/form-data) gesendet werden. Sie werden der Reihe nach zu einem Codec kombiniert. Es sind maximal 10 Videos zulässig, wobei die Gesamtgröße des kombinierten Videos auf 200 MB begrenzt ist. Insgesamt darf das Video bis zu 600 Sekunden lang sein. Beachten Sie, dass das Kombinieren mehrerer Videos die Anfragedauer erheblich verlängern kann. Kombinieren Sie die Videos nach Möglichkeit vorher.
- `description` (string, optional) — Optionale Textbeschreibung der gewünschten Musik. Maximal 4.100 Zeichen sind zulässig.
- `tags` (list of string, optional) — Optionale Liste von Stil-Tags, z. B. ['upbeat', 'cinematic']. Maximal 10 Tags sind zulässig.
- `model_id` (enum, optional) — Das für die Generierung zu verwendende Modell.
- `add_sfx` (boolean, optional) — Wenn true, Soundeffekt-Hinweise aus dem Video einbeziehen.
- `separate_tracks` (boolean, optional) — Wenn true, geben Sie statt einer einzelnen gemischten Datei eine ZIP-Datei mit separaten Musik- und Soundeffekt-Audiospuren zurück. Verwenden Sie dies für mehr Flexibilität beim Übereinanderlegen der Spuren.
- `use_audio_as_reference` (boolean, optional) — Wenn true, analysieren Sie die Audiospur des Videos und verwenden Sie Genre, BPM, Instrumentierung, Stimmung und Verlauf als Referenzmerkmale für die Musikgenerierung.
- `sign_with_c2pa` (boolean, optional) — Ob der generierte Song mit C2PA signiert werden soll. Gilt nur für MP3-Dateien.
