Set the Fading between an Endpoint Story and other elements

Create an Endpoint Story where all the elements have the same length as the neutral element.

Load the audio element preceding the Endpoint Story and the neutral element of the Endpoint Story in the OTM and adjust the overlap and the fade values. Save your changes.

Go to the next transition and adjust the overlap and the fade values between the neutral element and the audio element following the Endpoint Story. Save your changes.
