# Vídeo a Música

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

Genera música de fondo a partir de uno o varios archivos de vídeo. Los vídeos se combinan en orden. Las etiquetas opcionales de descripción y estilo influyen en la música generada.

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) — Cuando enable_logging se establece en false, se usará el modo de retención cero para la solicitud. El modo de retención cero solo puede utilizarse por clientes Enterprise.

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `videos` (files, required) — Uno o más archivos de vídeo enviados mediante una matriz FormData (multipart/form-data). Se combinarán en un único códec por orden. Se permite un máximo de 10 vídeos y el tamaño total del vídeo combinado está limitado a 200 MB. En total, el vídeo puede durar hasta 600 segundos. Ten en cuenta que combinar varios vídeos puede aumentar considerablemente la duración de la solicitud. Si es posible, combina los vídeos previamente.
- `description` (string, optional) — Descripción de texto opcional de la música que quieres. Se permite un máximo de 4100 caracteres.
- `tags` (list of string, optional) — Lista opcional de etiquetas de estilo (por ejemplo, ['upbeat', 'cinematic']). Se permite un máximo de 10 etiquetas.
- `model_id` (enum, optional) — El modelo que se debe usar para la generación.
- `add_sfx` (boolean, optional) — When true, incorporate SFX cues from the video.
- `separate_tracks` (boolean, optional) — When true, return a ZIP with separate music and SFX audio tracks instead of a single mixed file. Use this for more flexibility to layer the tracks.
- `use_audio_as_reference` (boolean, optional) — When true, analyze the video's audio track and use its genres, BPM, instrumentation, mood, and arc as reference characteristics for music generation.
- `sign_with_c2pa` (boolean, optional) — Si se firma la canción generada con C2PA. Solo aplicable a archivos mp3.

## Response

## Errors

### 403 Forbidden Error

- `any`

### 422 Unprocessable Entity Error
