File Upload Requirements

Before using the Motion Control API, you need to upload your image and video files:

Step 1 · Upload Reference Image

Use the File Upload API to upload your reference image showing the subject.

File Upload API — Learn how to upload images and get file URLs

Requirements:

File Type: JPEG, PNG, or JPG format
Max File Size: 10MB per file
Content: Clear image showing the subject's head, shoulders, and torso

Step 2 · Upload Motion Video

Upload a video that defines the motion pattern you want to apply.

Requirements:

File Type: MP4 or QuickTime format
Duration: Between 3-30 seconds per video
Max File Size: 100MB per file
Content: Video clearly showing the subject's head, shoulders, and torso

Step 3 · Get File URLs

After upload, you'll receive file URLs that you can use in the input_urls and video_urls parameters.

WARNING

Supported image formats: JPEG, PNG, JPG (Max: 10MB)
Supported video formats: MP4, QuickTime (Max: 100MB, 3-30 seconds)
Videos must clearly show the subject's head, shoulders, and torso
Maximum one image and one video per request

Query Task Status

After submitting a task, use the unified query endpoint to check progress and retrieve results:

Get Task Details — Learn how to query task status and retrieve generation results

TIP

For production use, we recommend using the callBackUrl parameter to receive automatic notifications when generation completes, rather than polling the status endpoint.
