# Vidéo à musique

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

Génère une musique de fond à partir d'un ou plusieurs fichiers vidéo. Les vidéos sont combinées dans l'ordre. La description facultative et les tags de style influencent la musique générée.

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) — Lorsque enable_logging est défini sur false, le mode zéro rétention est utilisé pour la requête. Le mode zéro rétention est réservé aux clients Enterprise.

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `videos` (files, required) — Un ou plusieurs fichiers vidéo envoyés via un tableau FormData (multipart/form-data). Ils seront combinés dans un codec unique, dans l’ordre. Un maximum de 10 vidéos est autorisé, la taille totale de la vidéo combinée étant limitée à 200 Mo. Au total, la vidéo peut durer jusqu’à 600 secondes. Notez que la combinaison de plusieurs vidéos peut augmenter considérablement la durée de la requête. Si possible, combinez les vidéos au préalable.
- `description` (string, optional) — Description textuelle facultative de la musique souhaitée. 4 100 caractères au maximum sont autorisés.
- `tags` (list of string, optional) — Liste facultative de balises de style, par exemple ['upbeat', 'cinematic']. Un maximum de 10 balises est autorisé.
- `model_id` (enum, optional) — Le modèle à utiliser pour la génération.
- `add_sfx` (boolean, optional) — Lorsque la valeur est true, intégrez les indications d’effets sonores de la vidéo.
- `separate_tracks` (boolean, optional) — Lorsque la valeur est true, renvoyez un fichier ZIP contenant des pistes audio distinctes pour la musique et les effets sonores, au lieu d’un seul fichier mixé. Cela offre davantage de flexibilité pour superposer les pistes.
- `use_audio_as_reference` (boolean, optional) — Lorsque la valeur est true, analysez la piste audio de la vidéo et utilisez ses genres, son BPM, son instrumentation, son ambiance et son évolution comme caractéristiques de référence pour la génération musicale.
- `sign_with_c2pa` (boolean, optional) — Indique s'il faut signer le morceau généré avec C2PA. S'applique uniquement aux fichiers MP3.

## Response

### 200

Fichier audio généré correspondant à la vidéo. Le type de contenu et l'extension du fichier dépendent du paramètre output_format (mp3 par défaut).

## Errors

### 403 Forbidden Error

Abonnement requis.

- `any`

### 422 Unprocessable Entity Error

Erreur de validation, par exemple vidéos non valides ou manquantes.
