Property of [`CameraMoveOptions`](CameraMoveOptions.md) · stable · since 2.0.0

```ts
durationMs?: number;
```

0 lands exactly, without damping, before the next frame. A move called after a `durationMs: 0` write to the same target (a view after a view, a lens after a lens), in the same task too, starts from that write's value, never from the one last drawn: a 0 ms `set` then an eased `set` jumps, then glides. [`Camera.state`](Camera.state.md) says when a read returns that value. Counts as 0 while the shopper's system asks for reduced motion (spec section 6.2).

**Default:** 0

## Generic-API test (spec 3.1)

| Rule | Result |
| --- | --- |
| 1. Neutral name | pass: `durationMs` names no product |
| 2. A precedent | pass: [Unity Transform.LookAt](https://docs.unity3d.com/ScriptReference/Transform.LookAt.html) (row `G42`); [Babylon.js ArcRotateCamera setTarget, setPosition](https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Cameras/arcRotateCamera.ts) (row `G42`); [Babylon.js ArcRotateCamera lowerAlphaLimit, upperAlphaLimit, panning](https://github.com/BabylonJS/Babylon.js/blob/master/packages/dev/core/src/Cameras/arcRotateCamera.ts) (row `G7`) |
| 3. Two apps, or labs | pass: 6 apps (ledger: app-4f16d2f6da, app-b362a81c85, app-f9a32142f1, app-fc07850558, app-fc306ec3dc, app-fd09090420) |
| 4. The cheaper fix first | decided per need in Appendix B: rows `G42`, `G7` at tier stable (a member only where no rule, data, asset or app code serves the need) |
