Archivia il valore `id` restituito per controllare l'attività e scaricare il video completato. `POST /v1/videos` utilizza `multipart/form-data`. Invia i controlli come campi del modulo e ripeti ciascun campo di riferimento una volta per ogni input multimediale. ## Scegli un modello Imposta `model` su uno dei seguenti ID modello. Scegli una dimensione della richiesta dalla tabella del modello corrispondente in [Imposta durata e dimensione](#set-duration-and-size). | ID modello | Livelli di risoluzione | | ---------------- | ---------------------- | | `minimax-h3` | `768P`, `2K` | | `minimax-h3-max` | `480P`, `768P` | ## Scegli una modalità di input Entrambi i modelli utilizzano i campi seguenti. Imposta `model` sull'ID del modello selezionato. | Obiettivo | Campi obbligatori | Campi facoltativi | | ------------------------------------------------ | ------------------------------------------------------------------------ | ------------------------------------ | | Da testo a video | `model`, `prompt` | `seconds`, `size` | | Immagini di riferimento | `model`, `prompt`, uno o più URL o file `input_reference` | `seconds`, `size` | | URL, URI di dati o file del video di riferimento | `model`, `prompt`, uno o più campi `reference_videos` | `seconds`, `size` | | Audio di riferimento con un'immagine | `model`, `prompt`, `input_reference`, uno o più campi `reference_audios` | `seconds`, `size` | | URL del primo e dell'ultimo fotogramma | `model`, `prompt`, `first_frame` | `last_frame`, `seconds`, `size` | | Primo e ultimo fotogramma caricati | `model`, `prompt`, `first_frame` file | `last_frame` file, `seconds`, `size` | Gli esempi di richieste H3-Max includono la generazione da testo a video a entrambi i livelli di risoluzione, immagini di riferimento, riferimenti combinati di immagini/video/audio e primo e ultimo fotogramma. ## Usa immagini di riferimento Invia immagini di riferimento tramite `input_reference` come URL HTTPS accessibili pubblicamente o file caricati. Per più immagini, ripeti il campo nell'ordine delle immagini, con un URL o file per campo. Utilizza tutti gli URL o tutti i file in questo campo. Invia ogni URL separatamente anziché combinare gli URL in un valore separato da virgole. Puoi inviare fino a nove immagini di riferimento PNG o JPEG, sia tramite URL sia tramite file caricati. Mantieni ogni immagine caricata a 20 MiB o meno. Nel prompt, descrivi i dettagli visivi che il video generato deve preservare. ## Utilizzare video e audio di riferimento Invia `reference_videos` e `reference_audios` come valori di testo multipart o file caricati, utilizzando i formati indicati di seguito. Ripeti ogni campo una volta per input, utilizzando solo valori di testo o solo file all'interno di quel campo. Non combinare gli input in un valore separato da virgole. Campi diversi possono utilizzare tipi di input diversi, ad esempio un URL di immagine con un file audio caricato. Per combinare riferimenti di immagini, video e audio, invia `input_reference`, `reference_videos` e `reference_audios` nella stessa richiesta. | Campo | Input | Formato | | ------------------ | --------------------------------------------------------------------------- | -------------------------------------------------------- | | `reference_videos` | Un URL MP4 HTTPS diretto e pubblicamente accessibile o un file MP4 caricato | MP4 con video H.264; una traccia audio AAC è facoltativa | | `reference_videos` | Un URI dati Base64 completo in un campo di testo | `data:video/mp4;base64,` | | `reference_audios` | Un URL MP3 HTTPS diretto e pubblicamente accessibile o un file MP3 caricato | MP3 | Invia al massimo 12 input di riferimento in totale, inclusi non più di tre video e tre clip audio. Ogni clip video o audio deve durare 2–15 secondi. La durata video complessiva e la durata audio complessiva devono essere entrambe pari o inferiori a 15 secondi. Abbina l'audio di riferimento ad almeno un'immagine tramite `input_reference`. Descrivi il movimento, la tempistica o il suono che il video generato deve seguire. Mantieni ogni MP4 caricato a un massimo di 50 MiB e ogni MP3 caricato a un massimo di 15 MiB. Un MiB corrisponde a 1024 × 1024 byte. Gli esempi di richieste nella parte superiore di questa pagina mostrano URL MP4, URI dati MP4 e URL MP3 abbinati a un'immagine. ### Caricare un video di riferimento Carica un file MP4 per guidare la struttura dell'inquadratura e il movimento: ```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' ``` ### Caricare audio di riferimento con un'immagine Abbina un URL di immagine di riferimento a un file MP3 caricato: ```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' ``` ## Impostare il primo e l'ultimo fotogramma Invia `first_frame` per l'immagine iniziale e, facoltativamente, un `last_frame` per l'immagine finale. Ogni campo accetta un URL PNG HTTPS diretto e pubblicamente accessibile oppure un file PNG caricato. Mantieni ogni PNG caricato a un massimo di 20 MiB (20 × 1024 × 1024 byte). Non combinare i campi dei fotogrammi con i campi di immagini, video o audio di riferimento. Utilizza una richiesta separata per la generazione basata sui fotogrammi. Con gli input dei fotogrammi, `size` seleziona il livello di risoluzione. Il servizio può normalizzare le dimensioni finali dell'output in base ai fotogrammi forniti. Continua a inviare `size` nel formato `WxH`. Memorizza il valore restituito di `id`. Esegui il polling dell'attività finché `status` non è `completed` oppure `failed`. Al completamento dell'attività, scarica il contenuto video. ## Imposta durata e dimensioni Per entrambi i modelli, imposta `seconds` su un numero intero da `5` a `15`. Il valore predefinito è `5` secondi. Scegli una risoluzione e un rapporto d'aspetto dalla tabella per il tuo modello, quindi invia il valore corrispondente **Dimensione della richiesta** come `size` nel formato `WxH`. Per le richieste di testo e contenuti multimediali di riferimento, `size` seleziona il livello di risoluzione e il rapporto d'aspetto dell'inquadratura. Il servizio può normalizzare le dimensioni dell'output finale in base alla dimensione richiesta e ai contenuti multimediali di riferimento forniti. ### Dimensioni per `minimax-h3` Usa queste dimensioni della richiesta con `model=minimax-h3`: | Risoluzione | Rapporto d'aspetto | Dimensione della richiesta | | ----------- | ------------------ | -------------------------- | | `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` | ### Dimensioni per `minimax-h3-max` Usa queste dimensioni della richiesta con `model=minimax-h3-max`: | Risoluzione | Rapporto d'aspetto | Dimensione della richiesta | | ----------- | ------------------ | -------------------------- | | `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` | ## Flusso dell'attività Invia la richiesta del modulo multipart e memorizza il valore `id` restituito. Chiama l'endpoint [per recuperare un video MiniMax H3](./retrieve) finché `status` non è `completed` o `failed`. Quando l'attività è `completed`, chiama l'endpoint [per scaricare il contenuto video MiniMax H3](./retrieve-content) per salvare il file 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.
