# Control clip common properties
|
||
|
|
|
||
|
|
Use the Inspector window to change the common properties of a Control clip. You can only create a Control clip in a Control track. A Control clip is a special clip that controls a nested Timeline instance, Particle System, Prefab instance, or ITimeControl Script, depending on how you create the Control clip:
|
||
|
|
|
||
|
|
* If you create the Control clip from a GameObject with a Playable Director component associated with a Timeline Asset, then the Control clip controls a nested Timeline instance. If the GameObject parents other GameObjects associated with many Timeline Assets, then the Control clip controls multiple Timeline instances.
|
||
|
|
* If you create the Control clip from a GameObject with a Particle System component, then the Control clip controls a Particle System.
|
||
|
|
* If you create the Control clip from a GameObject linked to a Prefab, then the Control clip controls a Prefab instance.
|
||
|
|
* If you create the Control clip from a GameObject with a script that implements the ITimeControl interface, then the Control clip controls an ITimeControl Script.
|
||

|
The common properties of a Control clip include its name and Clip Timing properties. Not all common properties apply to all types of Control clips.

|
## Display Name
|
||
|
|
|
||
|
|
The name of the Control clip shown in the Timeline window.
|
||
|
|
|
||
|
|
## Clip Timing properties
|
||
|
|
|
||
|
|
Use the **Clip Timing** properties to position and change the duration of the Control clip.
|
||
|
|
|
||
|
|
Most timing properties are expressed in both seconds (s) and frames (f). When specifying seconds, a **Clip Timing** property accepts decimal values. When specifying frames, a property only accepts integer values. For example, if you attempt to enter 12.5 in a frames (f) field, the Inspector window sets the value to 12 frames.
|
||
|
|
|
||
|
|
Depending on the [selected Clip Edit mode](clp_about.md), changing the **Start**, **End** or **Duration** of a Control clip may create an insert or replace clips on the same track. You cannot create a blend between Control clips.

|
|**Property:** |**Description:** |
|
||
|
|
|:---|:---|
|
||
|
|
|**Start**|The frame or time (in seconds) when the Control clip starts. Changing the Start changes the position of the Control clip on its track in the Timeline Asset.<br />Changing the Start also affects the End. Changing the Start sets the End to the new Start value plus the Duration.|
|
||
|
|
|**End**|The frame or time (in seconds) when the Control clip ends.<br />Changing the End also affects the Start. Changing the End sets the Start to the new End value minus the Duration.|
|
||
|
|
|**Duration**|The duration of the clip in frames or seconds.<br />Changing the Duration also affects the End. Changing the Duration sets the End to the Start value plus the new Duration.|
|
||
|
|
|**Clip In**|Sets the offset of when the Control clip starts playing. The Clip In property only affects Particle Systems and nested Timeline instances.|
|
||
|
|
|**Speed Multiplier**|A speed multiplier that affects the playback speed of the Control clip. This value must be greater than 0. The Speed Multiplier property only affects Particle Systems and nested Timeline instances.|
