Stockez le `id` renvoyé pour interroger la tâche et télécharger la vidéo terminée. `POST /v1/videos` utilise `multipart/form-data`. Envoyez les contrôles sous forme de champs de formulaire et répétez chaque champ de référence une fois par entrée média. ## Choisir un modèle Définissez `model` sur l’un des ID de modèle suivants. Choisissez une taille de requête dans le tableau correspondant au modèle dans [Définir la durée et la taille](#set-duration-and-size). | ID de modèle | Niveaux de résolution | | ---------------- | --------------------- | | `minimax-h3` | `768P`, `2K` | | `minimax-h3-max` | `480P`, `768P` | ## Choisir un mode d’entrée Les deux modèles utilisent les champs ci-dessous. Définissez `model` sur l’ID du modèle que vous avez sélectionné. | Objectif | Champs obligatoires | Champs facultatifs | | ---------------------------------------------------- | ------------------------------------------------------------------------------- | --------------------------------------- | | Texte vers vidéo | `model`, `prompt` | `seconds`, `size` | | Images de référence | `model`, `prompt`, une ou plusieurs `input_reference` URL ou fichiers | `seconds`, `size` | | URL, URI de données ou fichier de vidéo de référence | `model`, `prompt`, un ou plusieurs champs `reference_videos` | `seconds`, `size` | | Audio de référence avec une image | `model`, `prompt`, `input_reference`, un ou plusieurs champs `reference_audios` | `seconds`, `size` | | URL de la première et de la dernière image | `model`, `prompt`, `first_frame` | `last_frame`, `seconds`, `size` | | Première et dernière images importées | `model`, `prompt`, `first_frame` fichier | `last_frame` fichier, `seconds`, `size` | Les exemples de requêtes H3-Max incluent la génération de vidéo à partir de texte aux deux niveaux de résolution, des images de référence, des références combinées d’image, de vidéo et d’audio, ainsi que des première et dernière images. ## Utiliser des images de référence Envoyez des images de référence via `input_reference` sous forme d’URL HTTPS accessibles publiquement ou de fichiers importés. Pour plusieurs images, répétez le champ dans l’ordre des images, avec une URL ou un fichier par champ. Utilisez uniquement des URL ou uniquement des fichiers dans ce champ. Envoyez chaque URL séparément au lieu de combiner les URL dans une valeur séparée par des virgules. Vous pouvez envoyer jusqu’à neuf images de référence PNG ou JPEG, que vous utilisiez des URL ou des fichiers importés. Limitez chaque image importée à 20 Mio ou moins. Dans le prompt, décrivez les détails visuels que la vidéo générée doit préserver. ## Utiliser une vidéo et un fichier audio de référence Envoyez `reference_videos` et `reference_audios` sous forme de valeurs textuelles multipart ou de fichiers importés, en utilisant les formats ci-dessous. Répétez chaque champ une fois par entrée, en utilisant uniquement des valeurs textuelles ou uniquement des fichiers dans ce champ. Ne regroupez pas les entrées dans une valeur séparée par des virgules. Différents champs peuvent utiliser différents types d'entrée, par exemple une URL d'image avec un fichier audio importé. Pour combiner des références d'image, de vidéo et d'audio, envoyez `input_reference`, `reference_videos` et `reference_audios` dans la même requête. | Champ | Entrée | Format | | ------------------ | ------------------------------------------------------------------------------ | ---------------------------------------------------------- | | `reference_videos` | Une URL HTTPS MP4 directe et publiquement accessible ou un fichier MP4 importé | MP4 avec vidéo H.264 ; une piste audio AAC est facultative | | `reference_videos` | Un URI de données Base64 complet dans un champ texte | `data:video/mp4;base64,` | | `reference_audios` | Une URL HTTPS MP3 directe et publiquement accessible ou un fichier MP3 importé | MP3 | Envoyez au maximum 12 entrées de référence au total, dont trois vidéos et trois extraits audio au maximum. Chaque clip vidéo ou audio doit durer de 2 à 15 secondes. La durée cumulée des vidéos et celle des fichiers audio doivent chacune être inférieures ou égales à 15 secondes. Associez l'audio de référence à au moins une image via `input_reference`. Décrivez le mouvement, la synchronisation ou le son que la vidéo générée doit suivre. La taille de chaque MP4 importé ne doit pas dépasser 50 MiB et celle de chaque MP3 importé ne doit pas dépasser 15 MiB. Un MiB correspond à 1024 × 1024 octets. Les exemples de requêtes en haut de cette page montrent des URL MP4, des URI de données MP4 et des URL MP3 associés à une image. ### Importer une vidéo de référence Importez un fichier MP4 pour guider la structure du plan et le mouvement : ```bash theme={null} curl \ https://api.cometapi.com/v1/videos \ -H "Authorization: Bearer $COMETAPI_KEY" \ --form-string 'model=minimax-h3' \ --form-string 'prompt=Follow the uploaded reference video shot structure and motion. No text.' \ --form-string 'seconds=5' \ --form-string 'size=1344x768' \ --form 'reference_videos=@/path/to/reference.mp4;type=video/mp4' ``` ### Importer un fichier audio de référence avec une image Associez une URL d'image de référence à un fichier MP3 importé : ```bash theme={null} curl \ https://api.cometapi.com/v1/videos \ -H "Authorization: Bearer $COMETAPI_KEY" \ --form-string 'model=minimax-h3' \ --form-string 'prompt=Animate the reference image and synchronize the motion with the uploaded reference audio. No text.' \ --form-string 'seconds=5' \ --form-string 'size=1344x768' \ --form-string 'input_reference=https://your-image-host/reference.png' \ --form 'reference_audios=@/path/to/reference.mp3;type=audio/mpeg' ``` ## Définir la première et la dernière image Envoyez `first_frame` pour l'image d'ouverture et, éventuellement, un `last_frame` pour l'image de fin. Chaque champ accepte une URL HTTPS PNG directe et publiquement accessible ou un fichier PNG importé. La taille de chaque PNG importé ne doit pas dépasser 20 MiB (20 × 1024 × 1024 octets). Ne combinez pas les champs d'image avec les champs d'image, de vidéo ou d'audio de référence. Utilisez une requête distincte pour la génération basée sur des images de début et de fin. Avec des images de début et de fin, `size` sélectionne le niveau de résolution. Le service peut normaliser les dimensions finales de sortie en fonction des images fournies. Continuez à envoyer `size` sous la forme `WxH`. Enregistrez `id` renvoyé. Interrogez la tâche jusqu'à ce que `status` soit `completed` ou `failed`. Lorsque la tâche est terminée, téléchargez le contenu vidéo. ## Définir la durée et la taille Pour les deux modèles, définissez `seconds` sur un entier compris entre `5` et `15`. La valeur par défaut est de `5` secondes. Choisissez une résolution et un rapport d’aspect dans le tableau correspondant à votre modèle, puis envoyez la valeur correspondante de **Taille de la requête** au format `size` dans `WxH`. Pour les requêtes de texte et de médias de référence, `size` sélectionne le niveau de résolution et le rapport d’aspect du cadrage. Le service peut normaliser les dimensions finales de sortie selon la taille demandée et les médias de référence fournis. ### Tailles pour `minimax-h3` Utilisez ces tailles de requête avec `model=minimax-h3` : | Résolution | Rapport d’aspect | Taille de la requête | | ---------- | ---------------- | -------------------- | | `768P` | `21:9` | `1536x672` | | `768P` | `16:9` | `1344x768` | | `768P` | `4:3` | `1024x768` | | `768P` | `1:1` | `768x768` | | `768P` | `3:4` | `768x1024` | | `768P` | `9:16` | `768x1344` | | `2K` | `21:9` | `2912x1280` | | `2K` | `16:9` | `2544x1456` | | `2K` | `4:3` | `1920x1440` | | `2K` | `1:1` | `1440x1440` | | `2K` | `3:4` | `1440x1920` | | `2K` | `9:16` | `1440x2560` | ### Tailles pour `minimax-h3-max` Utilisez ces tailles de requête avec `model=minimax-h3-max` : | Résolution | Rapport d’aspect | Taille de la requête | | ---------- | ---------------- | -------------------- | | `480P` | `21:9` | `1120x480` | | `480P` | `16:9` | `864x480` | | `480P` | `4:3` | `640x480` | | `480P` | `1:1` | `480x480` | | `480P` | `3:4` | `480x640` | | `480P` | `9:16` | `480x864` | | `768P` | `21:9` | `1792x768` | | `768P` | `16:9` | `1360x768` | | `768P` | `4:3` | `1024x768` | | `768P` | `1:1` | `768x768` | | `768P` | `3:4` | `768x1024` | | `768P` | `9:16` | `768x1360` | ## Flux de tâches Envoyez la requête de formulaire multipart et stockez la valeur `id` renvoyée. Appelez [Récupérer une vidéo MiniMax H3](./retrieve) jusqu’à ce que `status` soit `completed` ou `failed`. Lorsque la tâche est `completed`, appelez [Télécharger le contenu vidéo MiniMax H3](./retrieve-content) pour enregistrer le fichier MP4. ## OpenAPI ````yaml api/openapi/video/minimax-h3/post-create.openapi.json POST /v1/videos openapi: 3.1.0 info: title: MiniMax H3 Video Create API version: 1.0.0 description: >- Create an asynchronous MiniMax H3 or H3-Max video task from text, reference media, or first and last frames through CometAPI.
