# Video to Music

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

Genereer achtergrondmuziek op basis van een of meer videobestanden. Video's worden op volgorde gecombineerd. Optionele beschrijvingen en styletags beïnvloeden de gegenereerde muziek.

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`

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `videos` (files, required) — Een of meer videobestanden die via een FormData-array (multipart/form-data) worden verzonden. Ze worden op volgorde gecombineerd tot één codec. Er zijn maximaal 10 video's toegestaan, waarbij de totale grootte van de gecombineerde video beperkt is tot 200 MB. In totaal mag de video maximaal 600 seconden lang zijn. Let op: het combineren van meerdere video's kan de requestduur aanzienlijk verlengen. Combineer de video's indien mogelijk vooraf.
- `description` (string, optional) — Optionele tekstbeschrijving van de muziek die je wilt. Er zijn maximaal 4100 tekens toegestaan.
- `tags` (list of string, optional) — Optionele lijst met stijltags (bijv. ['upbeat', 'cinematic']). Er zijn maximaal 10 tags toegestaan.
- `model_id` (enum, optional) — Het model dat voor de generatie moet worden gebruikt.
- `add_sfx` (boolean, optional) — Wanneer true, neem je SFX-signalen uit de video op.
- `separate_tracks` (boolean, optional) — Wanneer true, retourneer je een ZIP met afzonderlijke audiotracks voor muziek en SFX in plaats van één gemixt bestand. Gebruik dit voor meer flexibiliteit bij het op elkaar leggen van tracks.
- `use_audio_as_reference` (boolean, optional) — Wanneer true, analyseer je de audiotrack van de video en gebruik je genres, BPM, instrumentatie, sfeer en opbouw als referentiekenmerken voor het genereren van muziek.
- `sign_with_c2pa` (boolean, optional) — Of het gegenereerde nummer met C2PA moet worden ondertekend. Alleen van toepassing op mp3-bestanden.

## Response

## Errors

### 403 Forbidden Error

Abonnement vereist.

- `any`

### 422 Unprocessable Entity Error
