This type of track can be used to adjust Unity’s global Time.timeScale
for the duration of the clip. The most common use would be to create bullet-time style effects. The sample demonstrates the following:
Create a TimeDilationTrack in timeline using the Add Track menu, found under the Timeline.Samples submenu. Add clips to the track, and use the inspector to set scale values for the clip, or use the inline curve editor to animate the scale values. Clips can also be overlapped to create transitions between clips.
