How to Create a Musical Slideshow With iPhoto

Choose the photos you want to show during your video.

Choose your music; make sure whatever song you choose is not DRM protected. You can use songs you have bought from the iTunes store, and you should not use any song that you do not have express permission to use.

Make sure your photos and your music are in digital formats that will work with iTunes and iPhoto. That means scanning your photos and importing them into your iPhoto library and ensuring that your music is in your iTunes library as well.

If you have a lot of photos in your iPhoto library, it may be easier for you to create a new album to sequester the photos you intend to use. From the File pull-down menu, select “new album.” Name it whatever you want, and then go back to your main library. You can drag and drop photos into your new album as you browse through your main library.

While still in your main library pull down the file menu and select "new slideshow." This will put you into a slideshow creation/editing tool set. You will have one photo in your slideshow. If it isn't one you want for your final product, delete it.

Click on the new album you created. Decide which photo you want to appear first, then drag and drop it into your album. Continue with this until you have all your photos in the slideshow in the order in which you want them to appear. If you’re going to do this the easy way (letting iPhoto time the music for you), don’t use too many photos. I’ve maxed out at 44 photos to a song that was about 2:12, or about three seconds per photo.

Once you have your photos in order, you can use the toolbar at the bottom to add transitions and effects.

When you’re reasonably happy with what you’ve got, keep iPhoto open, and open iTunes and create a new playlist. Drag and drop the song(s) for your slideshow into it..

Go back to iPhoto, and click on music in the toolbar below the photo display. A list of iTunes playlists will appear. Pick yours.

Preview your slideshow, and make adjustments to the number of photos, effects, etc. as needed. When you have finished, pull down the “share” menu and click “export.” This will turn you slideshow into a Quicktime .mov file. The transcoding takes a bit of time, so be patient.

Open a finder window, and find you movie. Open it and play it to make sure everything is the way that you want it to be. If it’s fine, you’re ready to upload it to youtube. Follow the instructions on the website, and you’re good to go.
