Overview

About this model

Depth Anything V2 extracts a precise per-pixel depth map from a single image or every frame of a video, producing a grayscale map where brightness encodes relative distance from the camera. For video input, frames are processed in batches on GPU and reassembled at the source resolution and frame rate, giving a temporally aligned depth sequence. This is commonly used as a motion and structure control signal for AI video generation models such as Seedance 2 and Seedance 2.5, where a driving video's depth map guides camera movement and scene geometry while the appearance is generated fresh. It is equally useful for 3D-aware compositing, relighting, background removal, and any pipeline that needs a stable geometric reference from ordinary RGB footage.

1Motion Transfer: Extract a depth video from a driving clip to control camera and scene motion in Seedance 2/2.5 video generation.

23D-Aware Compositing: Use per-pixel depth to composite, relight, or apply depth-of-field effects on ordinary footage.

3Background and Foreground Separation: Isolate subjects from backgrounds using relative depth instead of green-screen segmentation.

4Robotics and Spatial Analysis: Estimate relative scene geometry from a single camera for prototyping and research.

How to Use Depth Anything V2 API

Choose your input: Provide exactly one of video_url (a driving video for per-frame depth extraction) or image_url (a single frame for a one-off depth map).
Submit the request: Send a POST request to /api/v1/depth-anything with a publicly accessible URL.
Poll or use a webhook: The task runs asynchronously; poll the returned request ID or supply a webhook_url to be notified on completion.
Feed the output downstream: Use the returned depth map/video as the motion or structure control input for a video generation model such as Seedance 2 or 2.5, or for any depth-aware compositing pipeline.

curl -X POST "https://api.muapi.ai/api/v1/depth-anything" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://example.com/driving-video.mp4"
  }'

Retrieve output: Read the completed depth map URL (PNG for image input, MP4 for video input) from the standard prediction result.

Common Questions

Frequently asked

What is Depth Anything V2?

It is a monocular depth estimation model that produces a grayscale depth map from a single image or every frame of a video, where pixel brightness represents relative distance from the camera.

Should I provide video_url or image_url?

Provide exactly one. Use video_url to extract a per-frame depth video (e.g. for motion-transfer control signals), or image_url for a single-frame depth map.

What output format do I get back?

A video input returns a grayscale depth-map video at the same resolution and frame rate as the source. An image input returns a single grayscale depth-map PNG.

What is this used for with Seedance 2 or 2.5?

Seedance's motion-transfer workflows accept a depth video as a structure/motion control signal. Extract the depth map from a driving video with this API, then pass it into Seedance to guide camera movement and scene geometry while generating new appearance.

Is there a size or length limit?

The API accepts standard web-hosted image and video files. Very long videos increase processing time since every frame is run through the depth model; keep driving videos to the length you actually need for the downstream generation.

How is pricing calculated?

Video input is billed at $0.04 per second of input video. A single image input is billed at a flat $0.05 per request.
