# Creare un'attività di lip-sync avanzato Kling
> Crea attività video di lip-sync avanzato tramite CometAPI Kling POST /kling/v1/videos/advanced-lip-sync, inviando audio e impostazioni della controparte per generare risultati sincronizzati.
Usa questo endpoint per creare un'attività di lip-sync avanzato dopo aver già identificato i volti nel video sorgente.
## Prima di chiamarlo
* Inizia con [Lip-Sync](./lip-sync) per ottenere il `session_id` e i valori `face_id` disponibili
* Crea una o più voci `face_choose` che associano ogni volto a un segmento audio
* Usa `audio_id` per l'audio prodotto da un'attività precedente, oppure `sound_file` per un file audio ospitato
* Invia i campi temporali in millisecondi. Ad esempio, `sound_start_time: "0"` e `sound_end_time: "2000"` selezionano i primi 2 secondi.
* Assicurati che il segmento audio ritagliato sia di almeno 2000 ms e non superi la durata dell'audio sorgente
* Imposta `callback_url` o `external_task_id` solo quando hai bisogno della consegna tramite webhook o di un tuo id di tracciamento
## Flusso dell'attività
Esegui [Lip-Sync](./lip-sync) sul video sorgente e conserva il `session_id` restituito insieme ai valori `face_id` di destinazione.
Invia `session_id` e l'array `face_choose` tramite questo endpoint.
Salva l'id dell'attività restituito per i controlli di stato e il recupero del risultato finale.
Per il riferimento completo dei parametri, consulta la [documentazione ufficiale di Kling](https://kling.ai/document-api/apiReference/model/lipSync).
