# Créer une tâche d’édition multimodale Kling
> Créez une tâche d’édition vidéo multimodale Kling via CometAPI : POST /kling/v1/videos/multi-elements pour combiner plusieurs éléments et générer des vidéos de manière asynchrone.
Utilisez ce endpoint pour soumettre le job final d’édition vidéo multimodale une fois que votre session et vos sélections sont prêtes.
## Workflow complet
Commencez par [Initialize Video for Editing](./initialize-video-for-editing) pour obtenir le `session_id` du clip que vous souhaitez modifier.
Utilisez [Add Video Selection](./add-video-selection) et, si nécessaire, [Preview Selected Video Area](./preview-selected-video-area) pour affiner la région d’édition.
Envoyez le `session_id`, le `edit_mode`, le `prompt` final, ainsi que tous les paramètres de génération facultatifs via ce endpoint, puis enregistrez l’id de tâche renvoyé pour les vérifications de statut.
## Avant de l’appeler
* Assurez-vous que la session de sélection est déjà initialisée
* Vérifiez que votre sélection de région est correcte avant de consommer un appel de génération
* Exécutez les appels de suivi de sélection sur le même compte et avec le `session_id` exact renvoyé lors de l’initialisation
* Définissez `edit_mode` sur `addition`, `swap` ou `removal`
* Fournissez `image_list` pour `addition` et `swap` ; omettez `image_list` pour `removal`
* Envoyez `duration` sous forme de chaîne comme `"5"` ou `"10"` ; les exemples transmettent explicitement `"5"`
* Traitez cette route comme l’étape finale de génération, et non comme l’étape de configuration
* Ajoutez `image_list`, `negative_prompt`, `mode`, `duration`, `callback_url` ou `external_task_id` uniquement lorsque le workflow d’édition en a besoin
