# Depth Anything Video

> Consistent depth maps from video

<CardGroup cols={1}>
  <Card title="Try Depth Anything Video in the Workbench" icon="flask" href="https://www.oxen.ai/ai/workbench?model=bytedance-depth-anything-video">
    Run this model interactively, tune parameters, and compare outputs.
  </Card>
</CardGroup>

**Model ID:** `bytedance-depth-anything-video`

Estimate temporally consistent depth maps from video using Video Depth Anything.

## Example request

<Tip>
  Use the [Workbench](https://www.oxen.ai/ai/workbench?model=bytedance-depth-anything-video) as a request builder: configure parameters for this model in the UI, then open the **API** tab to copy the exact cURL or Python call.
</Tip>

<Tabs>
  <Tab title="Sync">
    This blocks until the video is ready (typically 5-15 minutes). Prefer **Async** or **Async with SSE** for anything beyond quick experimentation.

    See the [video generation reference](/inference-api/reference/video_generation) for more details.

| `depth_model`        | `string`  | `"VDA-Large"` | Depth estimation model size. VDA-Large = best quality, VDA-Small = fastest. One of: VDA-Small, VDA-Base, VDA-Large. |
| `colormap`           | `string`  | `"grayscale"` | Colormap for depth visualization. One of: grayscale, turbo, inferno, magma, viridis.                                |
| `resolution`         | `string`  | `"auto"`      | Output resolution. Auto preserves input resolution up to 1080p. One of: auto, 360p, 480p, 720p, 1080p.              |
| `max_frames`         | `integer` | —             | Maximum number of frames to process. Leave unset to process all frames.                                             |
| `output_fps`         | `number`  | —             | Output video FPS. Leave unset to use the input frame rate.                                                          |
| `side_by_side`       | `boolean` | `false`       | If true, output a side-by-side original and depth comparison video.                                                 |
| `include_raw_depths` | `boolean` | `false`       | If true, exports raw float32 depths as an NPZ file.                                                                 |
