Replacing a transition

You can replace a transition by simply dropping a new transition on top of the old one. When you replace a transition, the alignment and duration are preserved; however, the settings for the old transition are discarded and replaced by the default settings for the new transition, or by the master transition settings if you have set them in the Transitions palette. See Changing transition settings.

To replace a transition:

Drag the new transition from the Transitions palette onto the existing transition in the Timeline window.
