# Adding clips

The Timeline window supports different methods of adding clips to tracks, depending on the type of track, where you click, and whether a clip or track is already selected.

The quickest method to add a clip is to right-click on an empty area within a track and select the appropriate Add option from the context menu. Depending on the track, the options for adding a clip change.

There are other ways to add clips:

* Select a clip option from the Track menu in the Track Header to add a clip at the location of the Timeline Playhead.
* Drag an animation Source Asset from the Project window to an empty area in the Timeline window to automatically create an Animation track and add an Animation clip.
* Drag an animation Source Asset from the Project window to an existing track in the Timeline window to add an Animation clip to the same track.
* Drag an audio Source Asset from the Project window to an empty area in the Timeline window to automatically create an Audio track and add an Audio clip.
* Drag a GameObject with a PlayableDirector component to create a nested Timeline instance. This automatically creates a Control track and adds a Control clip for the nested Timeline instance. 
* Drag a Prefab from the Project window to an empty area in the Timeline window to add a Prefab instance to your Timeline instance. This automatically creates a Control track and adds a Control clip for the Prefab instance.
* Drag a GameObject with a Particle component to add a particle effect to your Timeline instance. This automatically creates a Control track and adds a Control clip for the duration of the Particle effect. 

When you add a clip, the [selected Clip Edit mode](clp_about.md) determines how the added clip interacts with surrounding clips. For example, if you add an Animation clip or an Audio clip in Mix mode and the added clip intersects a clip on the same track, Timeline [creates a blend](clp_blend.md).
