# Wideo na muzykę

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

Wygeneruj muzykę w tle z jednego lub kilku plików wideo. Filmy są łączone po kolei. Opcjonalny opis i tagi stylu wpływają na generowaną muzykę.

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) — Gdy enable_logging ma wartość false, dla żądania zostanie użyty tryb zerowej retencji. Z trybu zerowej retencji mogą korzystać tylko klienci Enterprise.

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `videos` (files, required) — Co najmniej jeden plik wideo wysłany w tablicy FormData (multipart/form-data). Zostaną połączone kolejno w jeden plik z kodekiem. Możesz przesłać maksymalnie 10 filmów, a łączny rozmiar połączonego wideo nie może przekroczyć 200 MB. Łącznie wideo może trwać do 600 sekund. Połączenie wielu filmów może znacznie wydłużyć czas żądania. Jeśli możesz, połącz je wcześniej.
- `description` (string, optional) — Opcjonalny opis tekstowy muzyki, którą chcesz uzyskać. Maksymalnie 4100 znaków.
- `tags` (list of string, optional) — Opcjonalna lista tagów stylu (np. ['upbeat', 'cinematic']). Dozwolone jest maksymalnie 10 tagów.
- `model_id` (enum, optional) — Model do użycia przy generowaniu.
- `add_sfx` (boolean, optional) — Gdy ma wartość true, uwzględnia wskazówki SFX z filmu.
- `separate_tracks` (boolean, optional) — Gdy ma wartość true, zwraca plik ZIP z osobnymi ścieżkami audio muzyki i SFX zamiast jednego zmiksowanego pliku. Użyj tej opcji, aby elastyczniej nakładać ścieżki.
- `use_audio_as_reference` (boolean, optional) — Gdy ma wartość true, analizuje ścieżkę audio filmu i wykorzystuje jej gatunki, BPM, instrumentację, nastrój oraz strukturę jako cechy referencyjne do generowania muzyki.
- `sign_with_c2pa` (boolean, optional) — Czy podpisywać wygenerowany utwór za pomocą C2PA. Dotyczy tylko plików mp3.

## Response

### 200

Wygenerowany plik audio pasujący do filmu. Content-Type i rozszerzenie pliku zależą od parametru output_format (domyślnie mp3).

- File download.

## Errors

### 403 Forbidden Error

Wymagana subskrypcja.

- `any`

### 422 Unprocessable Entity Error

Błąd walidacji (np. nieprawidłowe lub brakujące filmy).

- `any`
