Assemble animation in sequences that you can rearrange and edit, like film clips in a nonlinear editor.
After animating a character or object with keyframes or motion capture, you can collect its animation data into a single, editable sequence. This animation sequence is called an animation clip. While you may create animation clips in a specific order with a specific storyline in mind, nonlinear animation refers to the process of moving, rearranging, manipulating, and blending those clips to produce a new series of motions.
In Maya, there are two types of clip: source clips and regular clips. Maya preserves and protects a character’s original animation curves by storing them in source clips. You do not use source clips to animate your characters. Instead, you use copies or instances of source clips called regular clips to animate your characters in a nonlinear way. See Animation clips.
The Time Editor lets you combine, mix, and edit animation using a clip-based non-linear workflow. You can bring any object or attribute in Maya that you can keyframe into the Time Editor as a clip, which can be edited in a non-destructive way, letting you experiment with combinations and variations of elements in your scene that you can the bake so can be used in Maya.
Moving, manipulating, and blending regular clips to produce a smooth series of motions for a character is the basis of nonlinear animation. In Maya, you manage all these aspects of a character’s nonlinear animation using the Trax Editor.
You can also use the Camera Sequencer, which lets you lay out and manage camera shots, then produce rendered movie footage of the animation in your scene. In the Camera Sequencer, shots are represented as a set of rectangles arranged on tracks, and you define and manipulate which camera is active at any point in time by manipulating the camera shots. When you’re satisfied with the layout and timing of camera shots, you can playblast movie clips of the animation.
What is the Time Editor?
The Time Editor is an animation non-linear editor that lets you edit and manage dozens of real-world rigs/characters in an easy-to-use workflow. The Time Editor gives you high-level control over animation letting you layer and mix sequences in a nonlinear, non-destructive way. It helps you reuse and fine-tune animation you've created with keyframes, expressions, and constraints.

What is the Trax Editor?
The Trax Editor is a high-level animation tool that lets you select and control characters and their animation clips, layer and blend animation sequences, synchronize your animation and audio clips, and drag-and-drop animation clips between mapped characters. See Mapping animation between characters in the Character Setup guide. You can work with any type of animation in the Trax Editor—except motion path animation.
For example, suppose you keyframed a character’s walk and you now want to turn it into a walk cycle. You can create a clip for the keyframe animation sequence, scale and trim the clip to get it to be the right length and to have similar start and end poses, and then cycle the clip to create a proper walk cycle. If you wanted to change the walk cycle’s pace or rhythm, you can then create a time warp curve for the clip, or if you wanted to turn the walk into a march, you can manipulate the character and key into the clip directly. You can do all this to the character’s walk sequence without destroying the original keyframe animation because you are working with clips.

What is the Camera Sequencer?
The Camera Sequencer is a tool that lets you create, re-arrange, and manipulate camera shots of your scene. Each shot defines which camera is active at any particular time, and for how long.
By adjusting the placement and timing of camera shots, you can effectively manage the ‘filming’ of the animation in the scene. When you finish manipulating camera shots in the Camera Sequencer, you can playblast the sequence into a rendered movie clip.
(Mac OS X) Camera Sequencer support on 64-bit systems is limited. For better performance and real-time results, run Maya in 32-bit mode to use the Camera Sequencer.

What is the Character Mapper?
With the Character Mapper window you can create a correspondence between a source and target character’s nodes or attributes so that you can import and export or copy and paste animation clips between mapped characters in the Trax Editor.
What are the Visor, Outliner, and Clip Library?
When working with nonlinear animation, there are three ways you can access your clips:
- Drag and drop source clips from the Visor to the Trax Editor
- Drag and drop regular or source clips from the Outliner to the Trax Editor
- Insert source clips into their respective characters in the Trax Editor using the Clip Library
See Source clips and Regular clips
Before you can drag and drop or copy and paste clips from one character to another, the characters must first be mapped. See Mapping animation between charactersin the Character Setup guide.
Visor
The Visor lists all the source clips in your scene as icons. You can select a clip icon in the Visor, and then middle-drag the clip onto a character in the track view area. Dragging a clip from the Visor onto a character in Trax adds a copy of the selected clip to that character. See Use the Visor with Trax and Visor.
The Visor has four tabs that let you view your scene’s nonlinear animation data. You can access all source clips and poses in your scene from the Character Clips,Character Poses, Unused Clips, and Unused Poses tabs. All the clips that are used by characters in your scene appear in the Character Clips and Character Poses tabs. All the clips and poses that are present in your scene, but are not used by a character, appear in the Unused Clips and Unused Poses tabs.
Outliner
The Outliner lists all the source and regular clips that are in your scene as text. You can select a clip name in the Outliner, and then middle-drag the clip onto a character in the track view area. Dragging a clip from the Outliner onto a character in Trax adds a copy of the selected clip to that character. See Use the Outliner with Trax, Use the Visor with Trax, and Visor.
Clip Library
The Clip Library is a menu in the Trax Editor that lets you create copies of source clips and poses for all the characters loaded in Trax. When you select a source clip or pose from the Library, a copy of the selected clip or pose is created and inserted into its respective character in Trax.
