Body
Text prompt describing the desired video. Supports both Chinese and English, recommended no more than 500 characters for Chinese or 1000 words for English. Maximum prompt length: 10000 tokens
Note:
- This model is text-to-video only and does not support
image_urls,video_urls, oraudio_urlsinput
"A macro lens focuses on a green glass frog on a leaf. The focus gradually shifts from its smooth skin to its completely transparent abdomen, where a bright red heart is beating powerfully and rhythmically."
Video aspect ratio, defaults to adaptive
Options:
16:9(landscape),9:16(portrait),1:1(square),4:3,3:4,21:9(ultrawide)adaptive: The model intelligently selects the best aspect ratio based on the prompt
Pixel values per resolution:
| Aspect Ratio | 480p | 720p |
|---|---|---|
| 16:9 | 864×496 | 1280×720 |
| 4:3 | 752×560 | 1112×834 |
| 1:1 | 640×640 | 960×960 |
| 3:4 | 560×752 | 834×1112 |
| 9:16 | 496×864 | 720×1280 |
| 21:9 | 992×432 | 1470×630 |
16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive "16:9"
Whether to generate synchronized audio, defaults to true
Options:
true: Video includes synchronized audio (voice, sound effects, background music) at no additional charge. It is recommended to place dialogue within double quotes to optimize audio generationfalse: Output silent video
true
Content filter, enabled by default true
Options:
true: Standard content safety check, this is the defaultfalse: Relaxes content restrictions, billed at +10% (1.1x). Illegal and prohibited content is always enforced regardless of this setting
Mutually exclusive with web search:
content_filter: falseandmodel_params.web_search: truecannot be used together; sending both returns a 400 parameter error- Keep
content_filter: true(the default) when web search is needed
true
HTTPS callback URL for task completion
Callback timing:
- Triggered when the task is completed, failed, or cancelled
- 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
2048characters
Callback mechanism:
- Timeout:
10seconds - Up to
3retries after failure (at1/2/4seconds 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
