            **Prompt requirements:**

            - Required and cannot be empty

            - Chinese and English are supported

            - Maximum length `7000` characters (Chinese and English are both
            counted by character)

            - The model may ignore some details in an overly long prompt


            **Input restrictions:**

            - This is a text-to-video model and accepts text input only

            - `image_start`, `image_end`, `image_urls`, `video_urls`, and
            `audio_urls` are not supported

            - Supplying any of these media fields returns a parameter error

            **Value restrictions:**
            - Only integers from `5` through `15`, inclusive, are supported
            - Decimals, numeric strings, `auto`, and `-1` are not supported
            - Output duration directly affects billing

            - `768p`: default


            **Notes:**

            - Omitting this parameter produces `768p` output

            - Output bitrate, frame rate, video codec, and audio codec are

            **Callback timing:**

            - Triggered when the task is completed or failed

            - Sent after billing confirmation is complete


            **Security restrictions:**

            - Only HTTPS protocol is supported

            - Callbacks to private IP addresses are prohibited (127.0.0.1,
            10.x.x.x, 172.16-31.x.x, 192.168.x.x, etc.)

            - URL length must not exceed `2048` characters


            **Callback mechanism:**

            - Timeout: `10` seconds

            - Up to `3` retries after failure (at `1`/`2`/`4` seconds after
            failure respectively)

            - Callback response body format is consistent with the task query
            endpoint response format

            - A 2xx status code is considered successful; other status codes
            trigger retries
