Multi-image referencemodel string (Required) The model name. For example: wan2.1-vace-plus. input object (Required) The basic input information, such as the prompt. Properties prompt string (Required) The prompt that describes the desired elements and visual characteristics in the generated video. The prompt can be in Chinese or English and must not exceed 800 characters. Each Chinese character or letter is counted as one character. Excess characters are automatically truncated. For more information about prompt techniques, see Video generation prompt guide. function string (Required) The name of the feature. For multi-image reference, set this to image_reference. The multi-image reference feature supports up to three reference images, which can contain entities and backgrounds, such as people, animals, clothing, and scenes. You can use the prompt parameter to describe the desired video content. The model then merges these images to generate a coherent video. ref_images_url array[string] (Required) An array of URLs for the input reference images. The URL must be accessible over the Internet and support the HTTP or HTTPS protocol. You can provide 1 to 3 reference images. If you provide more than 3 images, only the first 3 are used as input. Image requirements: Image format: JPG, JPEG, PNG, BMP, TIFF, or WEBP. Image resolution: The width and height must be between 360 and 2,000 pixels. Image size: Cannot exceed 10 MB. The URL cannot contain Chinese characters.
Suggestions: If you use an entity from a reference image, we recommend that each image contain only one entity. The background should be a solid color, such as white or a single color, to better highlight the entity. If you use the background from a reference image, you can use at most one background image, and it should not contain any entity objects.
| parameters object (Optional) The video processing parameters, such as watermark settings. Properties obj_or_bg array[string] (Optional) This parameter is an array that corresponds one-to-one with the ref_images_url parameter. Each element in this array specifies the purpose of the corresponding image, indicating whether it is an "entity" or a "background": Instructions: We recommend that you provide this parameter, which must have the same length as ref_images_url. Otherwise, an error is returned. You can omit this parameter only when ref_images_url is a single-element array, in which case the default value is ["obj"].
Example: ["obj", "obj", "bg"]. size string (Optional) The resolution of the generated video (width × height). The model currently supports generating 720p videos. Valid values: 1280 × 720 (default): The aspect ratio is 16:9, with a width of 1280 pixels and a height of 720 pixels.
720 × 1280: The aspect ratio is 9:16.
960 × 960: The aspect ratio is 1:1.
832 × 1088: The aspect ratio is 3:4.
1088 × 832: 4:3 aspect ratio.
duration integer (Optional) The duration of the generated video in seconds. This parameter is fixed at 5 and cannot be modified. The model always generates a 5-second video. prompt_extend bool (Optional) Specifies whether to enable prompt rewriting. If enabled, a large language model (LLM) rewrites the input prompt. This can significantly improve the quality of the generated video for short prompts but increases the processing time. seed integer (Optional) The random seed controls the randomness of the generated content. The value of this parameter ranges from [0, 2147483647]. If you do not provide a seed, the algorithm automatically generates a random number as the seed. To ensure that the generated content is relatively stable, use the same seed value for each request. watermark bool (Optional) Specifies whether to add a watermark. The watermark is located in the lower-right corner of the video and says "AI-generated". |
Video repaintingmodel string (Required) The model name. For example: wan2.1-vace-plus. input object (Required) The basic input information, such as the prompt. Properties prompt string (Required) The prompt that describes the desired elements and visual characteristics in the generated video. The prompt can be in Chinese or English and must not exceed 800 characters. Each Chinese character or letter is counted as one character. Excess characters are automatically truncated. For more information about prompt techniques, see Video generation prompt guide. function string (Required) The name of the feature. For video repainting, set the value to video_repainting. Video repainting extracts the entity's pose and actions, composition and motion contours, and line art structure from an input video. The model then combines this information with a text prompt to generate a new video with the same dynamic features. You can also replace the entity in the original video with a reference image, for example, to change a character's appearance while retaining the original actions. video_url string (Required) The URL of the input video. The URL must be publicly accessible and support the HTTP or HTTPS protocol. Video requirements: Video format: MP4. Video frame rate: 16 FPS or higher. Video size: Cannot exceed 50 MB. Video length: Cannot exceed 5 seconds. If it does, only the first 5 seconds are used. The URL cannot contain Chinese characters.
Output video resolution: If the input video resolution is 720p or lower, the output video retains the original resolution. If the input video resolution is higher than 720p, it is scaled down to 720p or lower while maintaining the original aspect ratio.
Output video duration: The output video has the same duration as the input video, up to a maximum of 5 seconds. For example: If the input video is 3 seconds long, the output is also 3 seconds long. If the input is 6 seconds long, the output is the first 5 seconds.
ref_images_url array[string] (Optional) An array of URLs for the input reference images. The URLs must be publicly accessible endpoints and support the HTTP or HTTPS protocol. Only 1 reference image is supported. We recommend that this image be an entity image used to replace the entity in the input video. Image requirements: Image format: JPG, JPEG, PNG, BMP, TIFF, or WEBP. Image resolution: The width and height must be between 360 and 2,000 pixels. Image size: Cannot exceed 10 MB. The URL cannot contain Chinese characters.
Suggestions: If you use an entity from a reference image, we recommend that each image contain only one entity. The background should be a solid color, such as white or a single color, to better highlight the entity.
| parameters object (Required) The video processing parameters, such as watermark settings. Properties control_condition string (Required) Specifies the method for video feature extraction. posebodyface: Extracts the facial expressions and body movements of the entity in the input video. This is suitable for scenarios that require the preservation of facial details.
posebody: Extracts an entity's body movements from the input video, excluding facial expressions. Use this for scenarios where you need to control only body movements.
depth: Extracts the composition and motion contours from the input video.
scribble: Extracts the line art structure from the input video.
strength float (Optional) Adjusts the control strength that the control_condition feature extraction method applies to the generated video. The default value is 1.0. The value range is [0.0, 1.0]. A larger value makes the generated video closer to the original video's actions and composition. A smaller value allows for more creative freedom. prompt_extend bool (Optional) Specifies whether to enable prompt rewriting. If enabled, an LLM rewrites the input prompt. This can significantly improve the quality of the generated video for short prompts but increases the processing time. If the text description is inconsistent with the video content, the model may misinterpret the prompt. To improve generation consistency and accuracy, we recommend that you disable prompt rewriting and provide a clear, specific description in the prompt. seed integer (Optional) The random seed controls the randomness of the generated content. The value of this parameter ranges from [0, 2147483647]. If you do not provide a seed, the algorithm automatically generates a random number as the seed. To ensure that the generated content is relatively stable, use the same seed value for each request. watermark bool (Optional) Specifies whether to add a watermark. The watermark is located in the lower-right corner of the video and says "AI-generated". |
Local editingmodel string (Required) The model name. For example: wan2.1-vace-plus. input object (Required) The basic input information, such as the prompt. Properties prompt string (Required) The prompt that describes the desired elements and visual characteristics in the generated video.

For more information about prompt techniques, see Video generation prompt guide. function string (Required) The name of the feature. For local editing, set the value to video_edit. Local editing lets you add, modify, or delete elements in a specified area of an input video. You can also replace the entity or background in the editing area to achieve fine-grained video editing. video_url string (Required) The URL of the input video. The URL must be publicly accessible and support the HTTP or HTTPS protocol. Video requirements: Video format: MP4. Video frame rate: 16 FPS or higher. Video size: Cannot exceed 50 MB. Video length: Cannot exceed 5 seconds. If it does, only the first 5 seconds are used. The URL cannot contain Chinese characters.
Output video resolution: If the input video resolution is 720p or lower, the output video retains the original resolution. If the input video resolution is higher than 720p, it is scaled down to 720p or lower while maintaining the original aspect ratio.
Output video duration: The output video has the same duration as the input video, up to a maximum of 5 seconds. For example: If the input video is 3 seconds long, the output is also 3 seconds long. If the input is 6 seconds long, the output is the first 5 seconds.
ref_images_url array[string] (Optional) An array of URLs for the input reference images. The URL must be an endpoint that is accessible over the Internet and support the HTTP or HTTPS protocol. Currently, only 1 reference image is supported. This image can be used as an entity or background to replace the corresponding content in the input video. Image requirements: Image format: JPG, JPEG, PNG, BMP, TIFF, or WEBP. Image resolution: The width and height must be between 360 and 2,000 pixels. Image size: Cannot exceed 10 MB. The URL cannot contain Chinese characters.
Suggestions: If you use an entity from a reference image, we recommend that each image contain only one entity. The background should be a solid color, such as white or a single color, to better highlight the entity. If you use the background from a reference image, the background image should not contain any entity objects.
mask_image_url string (Optional) The URL of the mask image. The URL must be a public URL and support the HTTP or HTTPS protocol. This parameter specifies the video editing area. You must specify either this parameter or the mask_video_url parameter. We recommend this parameter. The white area of the mask image (with a pixel value of [255, 255, 255]) indicates the part to be edited. The black area (with a pixel value of [0, 0, 0]) indicates the area to be preserved. Image requirements: Image format: JPG, JPEG, PNG, BMP, TIFF, or WEBP. The image resolution must be the same as the input video resolution (video_url). Image size: Cannot exceed 10 MB. The URL cannot contain Chinese characters.
mask_frame_id integer (Optional) This parameter is used only when mask_image_url is not empty. It specifies the frame ID of the video frame where the masked object appears. The default value is 1, which indicates the first frame of the video. The value must be in the range [1, max_frame_id], where max_frame_id = input video frame rate × input video duration + 1. For example, for an input video (video_url) with a frame rate of 16 FPS and a duration of 5 seconds, the total number of frames is 81 (16 × 5 + 1). Therefore, the value of max_frame_id is 81. mask_video_url string (Optional) The URL of the mask video. This URL must be an endpoint that is accessible over the Internet and supports the HTTP or HTTPS protocol. This parameter specifies the area of the video to edit. You must specify either this parameter or the mask_image_url parameter. The mask video must have the same format, frame rate, resolution, and length as the input video (video_url). The white area of the mask video (with a pixel value of [255, 255, 255]) indicates the part to be edited. The black area (with a pixel value of [0, 0, 0]) indicates the area to be preserved. | parameters object (Optional) The video processing parameters, such as watermark settings. Properties control_condition string (Optional) Specifies the method for video feature extraction. The default value is "", which means no extraction is performed. posebodyface: Extracts the facial expressions and body movements from an entity in the input video. This feature is suitable for scenarios where the entity's face is prominent in the frame and has clear features.
depth: Extracts the structural and motion contours from the input video.
mask_type string (Optional) This parameter is effective only when mask_image_url is not empty. It specifies the behavior of the editing area. tracking (default): The editing area dynamically follows the trajectory of the target object. This mode is suitable for scenes with moving objects.
fixed: The editing area remains fixed, regardless of the video content.
expand_ratio float (Optional) When mask_type is set to tracking, this parameter specifies the expansion ratio of the mask area. The value range is [0.0, 1.0]. The default value is 0.05. We recommend using the default value. A smaller value makes the mask area fit the target object more closely. A larger value expands the mask area more widely. expand_mode string (Optional) This parameter specifies the shape of the mask area when mask_type is set to tracking. The algorithm generates a mask video whose shape is based on the input mask image and the selected expand_mode. The following values are supported: hull (default): Polygon mode. A polygon wraps the masked object.
bbox: Bounding box mode, which uses a rectangle to enclose the masked object.
original: Raw mode. Preserves the shape of the original masked object as much as possible.
size string (Optional) The resolution of the generated video (width × height). The model currently supports generating 720p videos. Valid values: 1280 × 720 (default): The aspect ratio is 16:9, with a width of 1280 pixels and a height of 720 pixels.
720 × 1280: The aspect ratio is 9:16.
960 × 960: The aspect ratio is 1:1.
832 × 1088: The aspect ratio is 3:4.
1088 × 832: 4:3 aspect ratio.
duration integer (Optional) The duration of the generated video in seconds. This parameter is fixed at 5 and cannot be modified.

This can significantly improve the quality of the generated video for short prompts but increases the processing time. If the text description is inconsistent with the video content, the model may misinterpret the prompt. To improve generation consistency and accuracy, we recommend that you disable prompt rewriting and provide a clear, specific description in the prompt. seed integer (Optional) The random seed controls the randomness of the generated content. The value of this parameter ranges from [0, 2147483647]. If you do not provide a seed, the algorithm automatically generates a random number as the seed. To ensure that the generated content is relatively stable, use the same seed value for each request. watermark bool (Optional) Specifies whether to add a watermark.
