It escapes me completely what the practical differences are between these two. Except that one is a purple bubble and the other is a green strip. Both are pinned to a frame. And you can stack sound effects, so what's the advantage of using pinned background audio? You can't edit the length without going into the clip trimmer.
In other words what would keep me from arranging all audio clips as pinned sound effects?
(Yes I have RTFM but it doesn't say much about this).
I'll be thankful for any insight you may care to provide.

iMovie: Pinned Background audio vs. pinned sound effects1 Reply
Hi Pieter. The principle difference between pinned background audio and pinned "sound effect" audio is that the background audio automatically "stacks", for lack of a better word. By this I mean that when one background song ends, the next automatically begins. If that's something that makes your project easier to edit, then that's when you'd use it.
One other advantage to background audio is that you can add it to a project before you add video clips. The music won't actually play, since it only plays as long as the video in your project. But, you can add a background song, tap out the beats using the Snap to Beats feature in iMovie '09, then the clips you add will size up to match the beats you marked. |
