# Swapping Transitions from the Source Area to the Timeline

You can swap sources from the Source Area to a transition on the timeline.

To swap a transition from the Source Area to the timeline:

1. Select the custom transition icon.
2. Select the source in the Source Area.
3. Press ' (apostrophe).

   The material under the custom transition icon is replaced by the selected source material.

   NoteIf the source material differs in duration from the selected transition icon, only the first frames are used.
