You can merge two or more clips into a single clip. The clips to be merged can be positioned sequentially in a track or can be located on different tracks. 
The benefits of merging clips are as follows: 
- There are fewer clips to manage 
 
- If you merge a pair of blended clips, the resulting source clip has keys for the blended animation. You can activate the merged clip and edit its animation in the Graph Editor. 
 
- You can merge a single clip into a new clip. This is useful for creating an absolute clip from a relative clip, or for splitting a cycled clip. See Split clips. 
Note: 
If you don’t want to merge clips, you can still manage multiple clips at a time by grouping them. See Group and ungroup clips. 
 
  
 To merge clips

. The Merge Clip Options window appears. See Merge in the Trax Editor Edit menu.

 Note:  When clips merge, any gaps or overlapping between the animation clips are interpolated or blended.
