# Video oder Audiodatei synchronisieren

POST https://api.elevenlabs.io/v1/dubbing
Content-Type: multipart/form-data

Synchronisiert eine bereitgestellte Audio- oder Videodatei in die angegebene Sprache.

Reference: https://elevenlabs.io/docs/api-reference/legacy/dubbing/create

## 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

### Body (multipart/form-data)

This endpoint expects a multipart form with multiple files.

- `file` (file, optional) — Eine Liste von Dateipfaden zu Audioaufnahmen für das Klonen von KI-Stimmen
- `csv_file` (file, optional) — CSV-Datei mit Transkriptions-/Übersetzungsmetadaten
- `foreground_audio_file` (file, optional) — Nur zur Verwendung mit CSV-Eingaben
- `background_audio_file` (file, optional) — Nur zur Verwendung mit CSV-Eingaben
- `name` (string, optional) — Name des Synchronisationsprojekts.
- `source_url` (string, optional) — URL der Video-/Audioquelldatei.
- `source_lang` (string, optional) — Quellsprache. Erwartet einen gültigen Sprachcode nach iso639-1 oder iso639-3.
- `target_lang` (string, required) — Die Zielsprache, in die der Inhalt synchronisiert werden soll. Erwartet einen gültigen Sprachcode nach iso639-1 oder iso639-3.
- `target_accent` (string, optional) — [Experimental] Ein Akzent, der bei der Auswahl von Stimmen aus der Bibliothek angewendet wird und die Übersetzung über den bevorzugten Dialekt informiert.
- `num_speakers` (integer, optional) — Anzahl der für die Synchronisierung zu verwendenden Sprecher. Auf 0 setzen, um die Anzahl der Sprecher automatisch zu erkennen.
- `watermark` (boolean, optional) — Ob dem Ausgabevideo ein Wasserzeichen hinzugefügt werden soll.
- `start_time` (integer, optional) — Startzeit der Quellvideo-/Audiodatei.
- `end_time` (integer, optional) — Endzeit der Quellvideo-/-audiodatei.
- `highest_resolution` (boolean, optional) — Ob die höchstmögliche verfügbare Auflösung verwendet werden soll.
- `drop_background_audio` (boolean, optional) — Eine erweiterte Einstellung. Legt fest, ob Hintergrund-Audio aus der finalen Synchronisation entfernt wird. Dies kann die Qualität verbessern, wenn bekannt ist, dass das Audio keine Hintergrundspur enthalten sollte, etwa bei Reden oder Monologen.
- `use_profanity_filter` (boolean, optional) — [BETA] Ob Schimpfwörter in Transkripten mit '[censored]' zensiert werden sollen.
- `dubbing_studio` (boolean, optional) — Ob die Synchronisation für Bearbeitungen im Synchronisationsstudio oder als Synchronisationsressource vorbereitet werden soll.
- `disable_voice_cloning` (boolean, optional) — Verwenden Sie bei der Synchronisation statt eines Stimmklons eine ähnliche Stimme aus der ElevenLabs-Stimmbibliothek. Stimmen aus der Bibliothek zählen zum Limit für benutzerdefinierte Stimmen eines Workspace. Sind nicht genügend Plätze verfügbar, schlägt die Synchronisation fehl. Für diese Funktion benötigt der Aufrufer im Workspace die Berechtigung 'add_voice_from_voice_library', um auf neue Stimmen zuzugreifen.
- `mode` (enum, optional) — Der Modus, in dem dieser Synchronisierungsauftrag ausgeführt wird. Standardmäßig automatisch; verwenden Sie manuell, wenn Sie gezielt ein CSV-Transkript bereitstellen. Beachten Sie, dass der manuelle Modus experimentell ist und der Einsatz in der Produktion ausdrücklich nicht empfohlen wird.
- `csv_fps` (double, optional) — Beim Parsen einer CSV-Datei für die Synchronisation zu verwendende Frames pro Sekunde. Falls nicht angegeben, wird FPS aus Timecodes abgeleitet.

## Response

### 200

Erfolgreiche Antwort

- `dubbing_id` (string, required) — Die ID des Synchronisationsprojekts.
- `expected_duration_sec` (double, required) — Die erwartete Dauer des Synchronisationsprojekts in Sekunden.

## Errors

### 422 Unprocessable Entity Error

Validierungsfehler

- `detail` (list of ValidationError, optional)

## Types

### ValidationError

- `loc` (list of ValidationErrorLocItems, required)
- `msg` (string, required)
