- AI editing based on existing videos: style transfer, content replacement, element addition
- Optionally accepts reference images to specify target style or appearance
- Supports keeping the original video duration or customizing the output duration

Authorization stringAll API endpoints require Bearer Token authentication
Get your API Key:
Visit the API Key Management Page to get your API Key
Add it to the request header:
Authorization: Bearer YOUR_API_KEYRequest Parameters
model stringVideo generation model name, fixed as wan2.7-videoedit
nsfw_check booleanWhether to run content moderation before submitting the video task.
true: useomni-moderation-latestto review prompts and input imagesfalseor omitted: do not send a moderation request, adding no moderation cost or latency (default)
video_urls string" required>
Source video URL array for editing
Only the 1st video is used
Video constraints:
* Format: mp4, mov
* Duration: 2–10s
* Resolution: width and height in the range \[240, 4096] pixels
* Aspect ratio: 1:8 – 8:1
* File size: up to 100MB
prompt stringEditing instruction describing the desired changes, up to 5000 characters
If omitted, the model performs a default style transfer
Example: "Change the character's outfit to a red gown", "Replace the background with a snowy mountain scene"
negative_prompt stringNegative prompt describing unwanted content, up to 500 characters
image_urls string">
Reference image URL array, up to 4 images
Used to specify the target style or appearance (e.g., reference style for style transfer)
resolution stringOutput video resolution
Options:
720P- Standard1080P- High definition (default)
duration integerOutput video duration (seconds)
0(default): keep the full original video duration- Integer between
2-10: take the specified duration from the start
When duration=0, billing is based on the actual duration of the output video
The specified duration cannot exceed the duration of the original `video_urls` video
size stringOutput aspect ratio
Supported formats:
16:9- Landscape widescreen9:16- Portrait1:1- Square4:3- Landscape3:4- Portrait
If omitted, the aspect ratio matches the input video
prompt_extend booleanWhether to enable intelligent prompt rewriting
Significantly improves results for short prompts, but increases processing time
Default: true
watermark booleanWhether to add "AI Generated" watermark to the generated video
true: add watermarkfalse: no watermark (default)
seed integerSeed integer used to control the randomness of generated content
Value range: integer ≥0
* For identical requests, the model generates different results when receiving different seed values (e.g., omitting seed)
* For identical requests, the model generates similar results when receiving the same seed value, but exact consistency is not guaranteed
metadata objectaudio_setting stringAudio handling mode:
* auto (default): AI automatically regenerates matching audio based on the edited video content
* origin: force keep the original video audio, suitable for videos with important background sounds/dialogue
Response
code integerResponse status code, 200 on success
data arraystatus stringTask status, submitted when initially submitted
task_id stringUnique task identifier
