I’ve covered a lot of ground so far, and hopefully by now you have not only a good foundation for how to edit in iMovie, but also the confidence to try new things and explore features that aren’t obvious. In this chapter, I get more creative, using a variety of techniques to create a travel highlights movie, demonstrate how to incorporate green-screen special effects, create a music video, make a sports highlight video using iMovie’s clever Sports Team Editor, and build a custom soundtrack for a movie using the looping capabilities of GarageBand.
So far in this book, when working with music, you’ve added music to a previously edited movie. Perhaps if you’re the creative type, you’ve already played with editing your movie a bit to sync more closely with the music, but even in that case, the movie came first. In some instances, though, you may want to start with the music. Music videos are a great example, where the visuals serve the beat.
Music videos are only one example of where this technique might be useful. Slideshows, montage and action sequences, and movie trailers are other examples of when this technique could be useful. In fact, iMovie’s movie trailers feature, at heart, uses the techniques described here, just in a more guided interface.
To start with the music and work from there, use iMovie’s beat markers. This feature lets you build a project full of edit points and then populate the movie with video and photo clips, which are all automatically cut to the markers.
• Using the audio waveform as a guide, create a new beat marker by dragging a marker from the Beat Marker icon to the clip (Figure 5.2).
Figure 5.2. Drag from the Beat Marker icon to add a new beat marker.
• Play the song by pressing the spacebar or the backslash () key, and then press the M key whenever you want to add a beat marker. Don’t worry about being exact—you can move the markers later.
Think like an editor while you add markers. If you add too many markers you’ll end up with a bunch of really quick edits (although that may be the effect you want).
If you don’t see Remove Beat Marker in the contextual menu, you’re not hovering close enough to the marker. Click outside of the menu to close it and try again. You can also Control-click an empty part of the song and add a beat marker by selecting Add Beat Marker.
I often find it’s easiest to roughly define clip selections, drag them into the project, and then open them in the Clip Trimmer to precisely edit the selection. This enables me to work more quickly and to synchronize the clip selections with the music more closely.
For most music videos, you want the song to be the only audio playing. To quickly mute the video clips in the project, select them all and choose Clip > Mute Clips or press Command-Shift-M.
• Drag a new beat marker to the track. iMovie splits the clip that’s bisected by the new marker.
• Drag a beat marker to a new location. iMovie adjusts the durations of affected clips to accommodate the change.
• Delete a beat marker. iMovie asks how you’d like to deal with the edit at that spot (Figure 5.4).
Figure 5.4. iMovie needs guidance when you delete a beat marker.
As much as possible, perform a first edit of your music video using the beat markers and the Clip Trimmer. If you delete a clip in the Project browser, iMovie warns that doing so can knock everything out of sync.
With the clips you want to use in place, edit them using the techniques described in Chapter 4. For example, use the Replace edits to swap one clip for another; or, to use a different portion of the same clip, open the clip in the Clip Trimmer and drag using the bottom of the selection border to make the other portion visible while still maintaining the clip’s duration. The Precision Editor is especially helpful, because you can see how clip edges interact at the edit point.
Narrators are often maligned in dramatic films—it’s commonly an indication that the screenwriter or director got sloppy and needed to employ a narrator to help explain the story. But in documentary films they can be essential. Imagine March of the Penguins without Morgan Freeman’s mellifluous narration.
Whether you’re adding detail to vacation highlights or explaining something technical, you can record audio directly into the iMovie timeline.
Modern Macs include built-in microphones, but you’ll get much better results if you use an external mic. The built-in ones are designed for chatting via audio or video, not for making audio recordings of any quality. The easiest way to attach an external microphone is to use a USB mic. Many models are available, from expensive options by SE Electronics, Rode, and MXL, to more affordable ones by Logitech and Blue.
Figure 5.7. The voiceover appears as a purple audio clip.
Make sure you click the clip or press the spacebar to stop recording; if you close the Voiceover window (or press the O key), your recording isn’t saved.
You can record multiple takes and then delete the ones you don’t like (Figure 5.8). Be aware that when you play your project back you’ll hear all your takes at once unless you mute some of them.
Voiceover recordings are regular audio clips, which means you can edit them like any other clip. If the beginning of one recording sounds great but includes a flub later, you can trim away the error and record just the section you need (Figure 5.9).
Figure 5.9. Mix and match voiceover recordings to get the best result.
The modern version of iMovie was designed for making travel videos. I’m being literal: An Apple engineer went on a diving vacation and wanted a better, faster way to cut together the footage he shot. Although iMovie is used for making everything from family videos to school projects, my guess is that a majority of movies out there relate people’s epic vacation adventures. This project uses a theme to provide structure, and includes an animated map to show where you’ve been.
Although applying a theme for the project is entirely optional, it provides a framework for your movie and automatically adds many titles and transitions.
Figure 5.11. Theme elements are added automatically.
Each theme includes a handful of different title and transition types. Open the Titles or Transitions browser to view theme-specific options above the standard complement of options.
In one of my early travel videos, I painstakingly attempted to replicate the Indiana Jones-style map where a line progresses from location to location on a map to indicate our travel route. Now, iMovie makes it extremely easy.
Easily change the map style by dragging a different map onto the map in the Project browser.
When you add a map in the Bulletin Board theme, the maps that appear in the background of the theme transitions change to match the style of the one you added.
Almost as soon as I started writing about iMovie years ago, I started to receive questions from parents and coaches who were using iMovie to create weekly recaps of sporting events for their teams to watch and learn from. iMovie ’11 includes a new feature, the Sports Team Editor, an internal team database you can access for such sports highlight movies.
iMovie’s Sports Team Editor is designed to keep track of your team and be available for upcoming videos.
The default player information is pretty generic, but you can customize the columns. Click the expansion triangle next to Sports at the bottom of the window, and double-click a label for your sport to change it.
If you already track your team information in a spreadsheet or other database, export the data to a tab-delimited text file. You can then import that into the Sports Team Editor and save some time.
The Sports Team Editor, unsurprisingly, ties into iMovie’s Sports theme, with some transitions that take advantage of the player information.
Create a new project using the Sports theme. If you’ve already created a project, you can switch to the Sports theme by choosing File > Project Theme (or pressing Command-Shift-J).
If the option to automatically add transitions and titles is enabled, iMovie creates those items on its own. However, the coolest ones are titles that need to be added manually. Open the Titles browser and check out the following:
• Score. Add this title to drop a game score summary from the top of the screen. In the pop-ups that appear in the Viewer, specify each team and then enter a number in the score fields provided.
• Team vs Team. Good for placing near the front of the video, this title lets you choose which teams are playing and displays their logos.
• Player Stats. Add this title to overlay a player’s information. Choose the player in the pop-up menu that appears (Figure 5.16).
Figure 5.16. Adding a Player Stats title to a clip
If you change any information in the Sports Team Editor, an alert appears at the bottom of the window informing you that the project contains outdated team information and needs to be updated. Click the Update Project button.

I’ll admit it, one reason I go to see summer Hollywood movies is the special effects. Compared to effects just 20 years ago, what artists can do with pixels now is amazing. Now, I won’t pretend that you can get that level of quality in iMovie, but you can take footage shot against a green screen or a blue screen and project something else in its place. Imagine shooting a video podcast, or creating a school report where your child stands in front of a diagram and points to key sections of it. Or really, just imagine yourself in a galaxy far, far away...
Why green or blue? iMovie looks for a broad range of color, so if you happen to be wearing something that’s green, you’d want to use a blue screen; use a green screen if something in the video is blue.
The first thing you need is some green or blue material to drape behind your subject. That can be an inexpensive piece of cloth from a fabric store or even a wall or board painted a solid color. Any area that’s green or blue will be rendered invisible when you add it to your iMovie project (Figure 5.17).
Figure 5.17. Green screen for all your dramatic readings
When setting up the scene, try not to project harsh shadows on the background. Also try to avoid items with reflective surfaces that might pick up some of the green color.
When shooting the green-screen footage, move out of the frame at the end of a scene so the camera records a few frames of just the area with the green screen. iMovie can use that to better identify areas that should be masked.
A green-screen clip works similar to a cutaway (described in Chapter 4) in that it overlays other footage in your project. When you add it as a green-screen or blue-screen clip, those colors are knocked out.
Figure 5.18. Adding the clip as Green Screen
iMovie automatically removes the green or blue areas, which you can see in the Viewer (Figure 5.19).
iMovie doesn’t have the advanced features found in professional compositing software, but there are a few things you can do to try to improve the appearance of the green-screen effect.
Figure 5.20. I unintentionally included an area outside the green screen when shooting, which isn’t hidden (left). Cropping that edge removes the gaffe (right).
Earlier I suggested that you step out of the frame when recording and capture the green screen by itself. That’s to take advantage of the Subtract Last Frame feature, where iMovie performs some extra color cleanup using that frame as a guide.
Figure 5.21. By itself, the green-screen clip gave iMovie some trouble around the book (left). With Subtract Last Frame enabled, the noise disappeared.
One other technique to improve the mask is to adjust the green or blue gain sliders in the Video inspector. Your mileage will definitely vary, but it’s worth a try.

Software needed: GarageBand ’11
You’ve already used iMovie’s built-in audio clips and imported songs into a movie from your iTunes library, but what if you want something original? If you own both iMovie and GarageBand (either purchased separately through the App Store or as part of the iLife ’11 package), you have all the tools you need to create your own soundtrack—even if you don’t know a lick about making music.
GarageBand ships with thousands of short audio snippets called loops, brief segments of music that can be repeated—looped—to create sections of a song. They’re typically played by one instrument or instrumental group, like a guitar, a drum kit, or a horn section. By layering and combining various loops, you can quickly and easily create a unique composition. For this project, you’ll need a movie that’s roughly two to three minutes in length.
I highly recommend two excellent books by my colleague Jeff Tolbert. If you’re new to GarageBand, read Take Control of Making Music with GarageBand ’11. If you already know how to play an instrument, you need (yes, need) Take Control of Recording with GarageBand ’11 (www.takecontrolbooks.com/news/garageband).
As you work to build a soundtrack for your movie, obviously you want to be able to reference the footage. To do that, you can import a version of the movie directly into GarageBand as its own track.
(It is possible to send the movie to GarageBand and export the final version from there, but it involves an extra layer of video compression between your original and the end result.)
I’m changing the key to A major here because I know I’m going to use certain loops that sound better in the key of A. This is not something you normally have to do when you create a project. You can always change the key later, too.
Figure 5.24. Adding the movie to the Movie track
GarageBand takes a moment to build thumbnails for your movie and then displays it in the timeline. Your movie’s audio appears in a separate Movie Sound track.
If you look carefully, you’ll notice a tiny preview of your video in the Movie Track header, to the left of the movie thumbnails. To see a bigger preview, double-click the thumbnail to open it in a larger floating window (Figure 5.25).
Figure 5.25. View a larger preview of your movie.
Now that your movie is in place, it’s time to start building some music. In order to do that, we need to get all the extraneous panes out of the way and open the Loop browser.
I’m being more detailed than usual in this project, specifying particular loops to use by way of example. Feel free to follow along, or use the tutorial as a general indicator of how to build your own score.
A “track” in GarageBand refers to a discrete lane of audio data. Each track usually carries a separate musical instrument, and you can independently adjust each track’s volume and effects without affecting other tracks in the song.
The Loop browser, as the name implies, is where GarageBand stores all of its loops. Looking for a drum beat or a guitar riff? This is where you’ll find it!
If you don’t see Picked Steel String 01 in the results list, your song may not be in the correct key. Click the icon in the LCD and switch to the Project mode (Figure 5.26). Change the key to A major.
Figure 5.26. Switching to the Project mode in order to change key
Figure 5.27. Adding a loop to the project
Regions are the GarageBand equivalent of clips. They each hold a discrete chunk of music or audio. Like iMovie clips, two regions can butt up against one another, but they can’t overlap.
Make sure Control > Snap to Grid is checked. This makes moving, looping, and aligning regions much easier.
The song is not very exciting yet, but it’s a start. In the next section, you’re going to add more loops and start building an actual song.
If your movie has sound, you may want to mute it or lower its volume. To mute it, click the Mute button underneath the track name. To lower its volume, drag the track volume slider to the left (Figure 5.29).
Figure 5.29. Muting the movie’s audio track
The loops Picked Steel String 01, 02, and 04 are all part of the same loop “family.” Apple specifically designed loop families so you could mix and match them on a track and it would sound like a natural performance. Some especially nice loop families to check out are Delicate Piano, Emotional Piano, and Fusion Electric Piano, among others.
Your project is starting to sound like a real song, but it definitely needs some other elements. In this next section, you’re going to add some new instruments and start to flesh out the arrangement.
At the beginning of this section I said you were going to create a rock soundtrack, and nothing says “rock” like a good backbeat. It’s time to add some drums.
The drumbeat starts playing along with the guitar. There may be a slight delay before the drumbeat begins. This is so the beat starts at the beginning of a measure and allows the two loops to synchronize.
You can adjust the volume of the drum loop by moving the volume slider at the bottom of the Loop browser. You can also use the volume slider to the left of the acoustic guitar regions to adjust the volume of the guitar track.
Notice that the drum track is green, while the guitar track is blue. This is because the guitar track is what GarageBand calls a Real Instrument track, which means that it’s an actual audio recording of a guitar player. The drum track, by contrast, is a Software Instrument track. Instead of being an actual recording of a drum kit, it’s a collection of instructions that trigger the computer to play samples—short recordings of individual drum hits that, combined together, sound like a real drum kit. One of the cool things about Software Instrument tracks is that you can actually edit the instructions and change the notes, or in this case the drum hits, that are being triggered. You can also change the instrument that’s playing the notes—to a different drum kit or even to a piano or a cello.
Things are starting to come together, but where to go next? You could repeat the section again and add more instruments, but that could get boring. Adding music to your movie should make it more exciting, not less. Instead, consider switching gears and adding a new section.
Option-dragging copies a region, but GarageBand is finicky about holding down the Option key before you start to drag. If you do these two actions at once, you end up dragging the loop itself and not a copy.
The cycle region enables you to audition one area of your song repeatedly. This makes it easier to find loops that work with a specific section or make small tweaks to a particular area of a song.
At this point in the process, you’ve got several elements going at once, and the song may be getting loud. Yes, loud is often good when it comes to rock and roll, but there is a limit. Look at the master level meter (Figure 5.33). If you see red dots to the right of the meters, see the sidebar below.
Figure 5.33. Clipping indicators
You’re going to be using a lot of the same loops over and over again. It would be great if GarageBand had a way to select some favorite loops so you didn’t have to keep hunting for the same loops in the Loop browser. Well guess what? It does!
This transitional section should be four measures long, not six, so you’ll need to crop the second loop.
The piece sounds great so far, but it’s time for some new blood. This is supposed to be a rock song, so how about some electric guitar?
It may help to zoom out a bit to see more of the timeline. To do so, drag the zoom slider, at the bottom of the track header section (Figure 5.38). Dragging left zooms out, and dragging right zooms in.
It’s time to finish this puppy. You’re going to copy and paste a few sections, add a couple more guitar parts, and fade the piece out.
Figure 5.39. Dragging a new guitar loop
You could add the new loop to the existing electric guitar track, but Edgy Rock Guitar 01 is quieter than 10, and for now, it’s easier to leave them on their own tracks to adjust their relative volumes.
Also check to make sure the movie sound is at an appropriate level. If there’s dialogue in your video that you want to be audible, you’ll need to turn the music down quite a bit.
Fade Out uses the last region in the song to determine where the fade-out ends. If your movie contains audio and is significantly longer than the song, the song won’t fade, only the movie sound will. To remedy this, do one of the following: Copy one or more sections of the song to make it longer; or, delete the Movie Sound track. You’re not going to use it until you reopen your video in iMovie anyway, so it’s unnecessary at the moment.
In this case, you’re going to bring your song back into iMovie and export the movie from there. But you also have the option of exporting directly from GarageBand. To do so, select Share > Export Movie to Disk before you mute the Movie Sound track.
Your song is now part of your iMovie project. The green area indicates the length of your song. If your movie is longer or shorter than your song, you can edit the movie to fit. You can also edit it so important cuts in your film happen in sync with musical changes. This makes it feel like the music “fits” your movie better.
Now pour yourself a cold beverage and relax in a comfy chair. You’ve just created your first GarageBand song! You can now use these techniques to create all kinds of great music using just the loops that come with GarageBand.
