You can change the timing of a clip without modifying the clip’s animation curves using time warps. Typically, you use time warps to reverse the animation in a clip, or to ease in or ease out of a clip’s animation.

You can create time warps automatically when you create or duplicate a clip, or you can select an existing clip and create a time warp for it. See Animate > Create Clip. By default, time warps are not created when a clip is created.

When you create a time warp for a clip, a time warp curve is added above the clip in its hierarchy and a green bar appears on the clip. See Time warps. You can manipulate this time warp curve to adjust how the time warp affects the animation in its clip.

To create a time warp for a clip

1. Select the clip for which you want to create a time warp.
2. Do one of the following:
   • In the Trax menu bar, select Create > Time Warp.
   • -click the clip, and select Create Time Warp from the menu that appears.
     

   The Time Warp Enable attribute is turned on for the clip node, and a new time warp curve appears in the clip. By default, the time warp curve extends from 0 to 100 and represents a percentage of its animation clip. The time of 0 is the start of the clip and the time of 100 is the end of the clip.

   In the track view area, a green bar appears on the clip to indicate that the clip is now affected by a time warp.

To edit a time warp

1. Select the clip that has the time warp.
2. In the Trax toolbar, click the Graph Anim Curves button.
3. In the Graph Editor outliner, select the time warp curve and click the Frame All button or press f to frame the time warp curve.
4. In the graph view, use the Insert Keys Tool to insert keys and use the Move Tool to adjust the curve.

   When working in the graph view with these tools, use the mouse button.
