Fade In or Fade Out to Black?

To have your movie fade in from black, click once on the Transition icon (it’s just to the right of the little scissors icon, at the top left of the Timeline panel, and circled above in red), and click on Fade With Black in the dialog that pops up. At the bottom of this dialog, you’ll see a Duration field. Enter how long you want that fade in to last, then drag- and-drop the Fade With Black transition onto the front of the first clip in your timeline. Now, when you hit Play, your movie will fade in from black. You fade out at the end of your movie pretty much the same way—scroll to the last clip in your movie, click on the Transition icon, click on Fade With Black, choose how long you want to fade out from the Duration field, and then drag-and-drop the Fade With Black transition onto the end of the last clip in your movie (as seen above, where a triangle has been added to the bottom right of the clip). Now your movie will fade out at the end.
