The Logical Blog by IconLogic

If you wanted to add voiceover narration to the movie, however, you may have run into a bit of a problem--there is only one row in the Windows Movie Maker timeline for audio. If there was a need to add background music to the presentation in addition to narration, you would be in a bit of a pickle. Click the Narrate Timeline tool. Drag your Narration recording(s) from the Collections area down to the Audio/Music portion of your timeline.
