iMovie has a nifty little feature that allows for the brainless creation of your own movie trailers. All you need to do is have some video footage, stills and know how to type. This feature is great for assembling short summaries of an event at your school or a family vacation etc and it takes all of about 15 minutes to come up with a very attractive video.
Not long ago I was asked by a teacher if it was possible to get rid of the “stock audio” tracks that are supplied with the movie trailer and replace them with her own music. The short answer is Yes!!!!
Here’s how to detach the “stock” audio file(s) that come with the iMovie trailer feature of the program and replace it with your own audio. To do this . . .
1) Save your trailer (video footage/project) to the “camera roll” on your iPad or iPhone.
2) Create a “new project” in iMovie.
3) import the trailer into the video section of your new project from your camera roll.
4) tap on the video shown at the bottom of your iMovie screen in the timeline. It will be highlighted in yellow once selected.
5) at the bottom left side of your screen you’ll see “video” and “audio”. Tap on “audio”.
6) now at the bottom right side of your screen you’ll see “detach”. Tap on detach.
7) the audio channel will now be separated from the video and highlighted in yellow. Tap on the “trash can icon”
8 now at the top right side of your screen you’ll see a menu – Videos /Photos /Audio. Choose “audio”.
9 you’ll then see your iTunes library that’s stored on your iPad. You can now choose whichever song you’d like to use by clicking on the song and then clicking on the arrow that appears when the song is selected. This will place the music at the start point of the video!
Hope this helps!
