# Quick Start: Motion

> Create a reusable Motion from a driving video.

Create a reusable **Motion** from a driving video once, then reference its ID from any number of [Video Remix](/v1/guides/quickstart-mix) renders without re-uploading the video. This is the `type=render` path of `POST /v1/motions` — see the [Motion 3D Quickstart](/v1/guides/quickstart-mocap) for the `glb` extraction instead, or the [Text-to-Motion Quickstart](/v1/guides/quickstart-text-to-motion) to generate a Motion from a text prompt with no source video at all.

Set `VIGGLE_API_KEY` and run the example below as-is — it uses a Viggle-hosted sample video, so you don't need to prepare your own motion video first.

## What you need

* An API key from the [Viggle Dashboard](https://portal.viggle.ai/keys), exported as `VIGGLE_API_KEY`

<Note>
  The examples below reference a placeholder sample asset URL (`https://assets.viggle.ai/samples/motion.mp4`). Swap in your own `motion_video`/`motion_video_url`, or Viggle's published sample asset once available.
</Note>

## Response

```json theme={null}
{
  "id": "mot_550e8400-e29b-41d4-a716-446655440000",
  "status": "queued",
  "name": "Quickstart motion",
  "progress": 0,
  "capabilities": [],
  "created_at": "2026-07-21T10:00:00+00:00",
  "completed_at": null,
  "error": null,
  "type": "render",
  "vsplat": null,
  "glb": null
}
```

Poll `GET /v1/motions/{motion_id}` every 3 seconds until `status` is `ready` or `failed`. Once ready, `id` is a **reusable Motion ID** — pass it as `motion_id` to [Render Video](/v1/api-reference/renders/create) (or the [Video Remix Quickstart](/v1/guides/quickstart-mix)) any number of times, without re-uploading the source video.

See [Pricing and retention](/v1/pricing#motion) for how Motion creation is billed — a `type=render` Motion has no separate preprocessing charge.
