When you are finished working with at TimeWarp curve, you can merge it with its function curve to make your changes permanent.

To merge a TimeWarp curve:

1. In the FCurves Properties pane, select the property whose function curve you want to merge with the TimeWarp curve.
2. In the TimeWarp pane, select the TimeWarp curve and click Merge.
3. Optional: In the Animation Layer editor, select the Base Layer (if it is not already selected) and view the final function curves for your animation.

After you have merged a TimeWarp curve with the Base Layer, you can delete the TimeWarp curve from the scene.
