When you edit media priorities in the Priority Editor, keyframes are not created by default. To create keyframes from the Priority Editor, the Auto Key button must be enabled. By default, the Auto Key button is set to off so as not to create keyframes when reordering media.

To create keyframes for a media priority change:

1. Display the Priority Editor by touching the swipe bar below the Media menu.
2. Click Auto Key to enable auto-keyframing.

   
   

3. Reorder priorities at different points in the timebar. Keyframes are automatically created as priorities are edited.
   NoteStop all priority auto-keying anytime by disabling the Auto Key button.
