How do I add a default transition in Premiere?

To set a default transition in Adobe Premiere Pro, apply a transition to a clip on your timeline and then designate it as the default. Here's how:

1. Apply the desired transition: Drag and drop the transition you want to use as your default (e.g., "Film Dissolve" as mentioned in the reference) onto the cut point between two clips in your timeline. You can find transitions in the Effects panel (typically located in the "Effects" workspace or accessible via the "Window" menu). Within the Effects panel, look in "Video Transitions."

2. Set as Default Transition: Right-click on the transition you just applied in your timeline.

3. Choose "Set Selected as Default Transition": From the context menu that appears, select the option labeled "Set Selected as Default Transition."

Now, whenever you apply the default transition (e.g., by selecting a cut point and using the shortcut Ctrl+D or Cmd+D), the transition you selected will be used.
