Edit video like a pro at you computer
Needed:

The best way to learn how to use iMovie is to work through the iMovie tutorial. You don't need any video clips (they are supplied within the tutorial). You will learn how to use the editing commands and how to export your completed video so others can view it. The tutorial will take about an hour to an hour and a half to complete, but you can stop and come back to it at anytime. To start the tutorial, open iMovie and pull down the "Help" file, choose "iMovie Tutorial" and follow the instructions.
Before you can import your video, you need to connect the camera to the computer. Use the 6-pin to 4-pin firewire cable. Be careful, do not force anything.

With computer and camera connected and on, and iMovie open, you are ready to import your video footage.


Clips are stored on the shelf, to the right of the screen. Each time you start "Import" you create a new and separate clip. iMovie also divides footage into separate clips at places where you stopped and started filming.
Once you've imported your clips, you are ready to start building your movie. You will see your clips on the shelf at the right of your screen. The clips are numbered, you can see the length of each clip, and an image of the first scene of each clip.
You can view a clip by clicking on it and clicking on the "Play" button.
To start making your movie;
Drag your selected clips from
the shelf down to the "Clip Viewer" at the bottom. 
The clip viewer displays the clips in the sequence they occur in your movie. You can rearrange the order by dragging and dropping the clip where you want them to appear.
Note: You have a choice between
the Clip Viewer (above) and the "Timeline Viewer"
which displays the movie's video track and two audio
tracks. Use the timeline viewer to position and edit
audio and video.

Cropping
and Editing:
Besides rearranging the order of your clips, you can also crop or shorten individual clips or delete certain sections. Include only the video you want. You can crop and split clips. You can also copy, paste, and replace sections of video. You can even replace video in a clip while keeping the audio contained in it.
Some clips are longer than you need or have excess footage a the beginning or end. To remove part of the beginning and/or end of a clip, you crop it. (cropping means to cut out).
To crop a video clip: Tip:
To remove a section in the middle of a clip, select it with
the crop markers, press the delete key to delete the
selected yellow portion. Remember, if you crop something by
mistake, you can pull down "Edit" and "undo"
the crop.
Viewing the movie in
progress:

As you are building your movie, you can view your progress in the monitor. You can drag the playhead to any point along the scrubber bar to start or stop the movie where you want using the play button. Remember, the space bar can also be used to start and stop viewing.
You can split a single clip into two clips. This is particularly useful if you want to keep an unused section of a clip on the shelf for later editing, or if you need to insert a title in the middle of a clip, or want to move part of a clip to another location.
To split a clip:
Transitions smooth the cuts between scenes (clips) and add visual appeal. You can put a transition at the beginning or end of movie, or between two clips.
Transitions include:
- Cross dissolve
- Fade in and out
- Pushes
- Overlap
- Scale down
To add a transition to a clip:
A transition icon appears between the clips, and a small progress bar
appears under it. When the progress bar disappears, the rendering is
done. You can continue editing while the transition is
rendering.
To preview the transition in the movie, place the playhead before the transition in the scrubber bar and click the play button.
A title lets you add descriptive text, such as credits, opening titles, etc. You can choose from a variety of styles, fonts, and colors.
You can place a title over a section of a video clip or create it as a separate clip with a black background.
To add a title to your movie:

To Edit an existing title:
You can add effects to your movie, such as color adjustments or a sepia tone ( a rust-tinted, old fashioned look).
To apply video effects to your movie:
When you use an effect, iMovie applies the effect to your movie project but leaves the original footage untouched on your hard drive. If you want to save hard drive space and you're sure you want to keep an effect, you can delete the copy of the original footage by clicking "Commit."
Creating
a Black or Still-Image Video Clip:
You can add a black video clip to create a blank, black pause between scenes. You can also capture a picture form your movie and use it as a still-image clip.
Creating black video clips:
A new black clip fills in the gap created on the left. Note: you cannot drag a clip to the right if there is a transition to the left of it.
Creating still-image clips:
Changing the duration of still-image clips:
The default duration of a still-image clip is 5 seconds.
Changing the Direction
and speed of video clips:
You can reverse the direction of one or more video clips. For example, make it play backwards. Or you can speed up your clip or have it play in slow motion.
To reverse the direction of video clips:
To adjust the speed of video:
To delete audio or video from your movie:
TIP: If you make a mistake, you can recover the deleted video or audio by choosing "Undo Clear" from the Edit menu. You can also choose "Restore Clip Media" from the "Advanced" menu.
Clips are automatically given a generic name in iMovie.
To give your clips names that are more useful to you;
- If the clip is in the clip viewer or shelf area, click the clip name and type a new name.
- If the clip is in the timeline viewer, double-click the clip and rename it in the Clip info window.
WARNING: You can rename clips in iMovie. However, to avoid breaking links between the movie project and the media file, do not rename the files in the movie project's Media folder.
There are many ways to bring audio into your movie, you can:
Once the audio is in your video, you can edit it in the following ways:
Volume adjustment:
When you adjust the iMovie volume, you only change how loud the computer's speaker sounds. You don't change the volume of files in your movie.
To adjust the iMovie volume, drag the volume slider.
There are two ways to add music to a movie; recording music from an audio CD, or importing an AIFF or MP3 audio file.
TIP: To prevent background sounds from overpowering important foreground sounds, reduce the volume of background audio clips.
Recording audio CD Music:
To record audio CD music into your movie:
- Click the "Audio" button.
- Insert the audio CD into your computer's CD-ROM drive.
- Select the track in Audio panel and do one of the following:

You can record you voice into your movie using a microphone connected to (or built in) you computer. Or, you can record voice narration with a digital camcorder and then import the digital video that contains the voice narration. Then you can extract the audio from the video.
To record a voice narration in your movie:
- Position the playhead where you want the narration to begin.
- Click the "Audio" button.
- Click the "Record Voice" button in the Audio panel.
- Speak into the microphone.
Use the volume level meter (above the Record Voice button) to determine how loud you should speak. For best result, keep the level between 50% and 75%.

To place the audio at a precise location in the movie:
- In the timeline viewer, position the playhead at the point in the movie where you want the audio clip to begin or end. (This creates a "ghost" playhead that marks the place for you).
- Drag the audio clip(s) or sound effects(s) to the ghost playhead.
Muting and adjusting the volume of clips:
You can adjust the volume of individual audio and video clips in your movie. This is important in making sure background sounds don't overpower import foreground sounds, such as voice narration.

To make audio fade in and/or out:
- Select the clip in the timeline viewer and click the "Fade In" and/or "Fade Out" boxes.
- You can adjust how long an audio fade lasts by double-clicking the clip and specifying the fade duration in the Clip Info dialog box.
Locking audio to specific video:
If you edit video after you have placed and positioned audio in your movie, you may find that you audio and video are no longer synchronized.
To avoid this problem, you can lock audio clips at specific points (frames) in the video. For example, you can lock the frame of a dog to the sound of a dog barking. Once the audio clip is locked to a specific video frame, it moves with that video frame and remains locked unless you specify to unlock it in the Advanced menu.
To lock audio to video:
- Select the audio clip(s).
- Position the playhead at the point where you want to audio and video to lock.
- Choose "Lock Audio Clip at Playhead" from the "Advanced" menu.

Once you have created your movie, you have a couple of choices of how you want to export it for viewing. You can;
Recording movie onto DV tape:
Connect your DV camcorder to your computer using a Firewire cable (as you did to get your video into your computer).
You can preview your
recorded tape in iMovie by setting the Mode Switch
to Camera mode. then use the playback controls to rewind
and play you movie.

Saving a movie as a QuickTime file:
Saving a movie as a QuickTime file allows you to play it on computers, post it on a Web page, send it as an e-mail, or save it on a CD. To do so:
The length of time it takes to export the movie and size of file depends on the length of the movie and the format you chose.
The "Formats" pop-up menu
contains these formats: QuickTime 4.0 or later is
required to view these formats on a computer (either Mac
or PC). You can download the latest version of
QuickTime for free here.
Saving a movie for DVD:
Exporting for iDVD creates a large, full-quality QuickTime movie that can be published on a DVD using iDVD. The movie can be played in a DVD player and viewed on a television or computer screen.
Saving a still picture from a movie:
You can create an image file by saving a frame of your movie.
To save a still image from video:
- Select the clip that contains the picture you want to export.
- Position the playhead so that the picture you want is showing in the iMovie monitor.
- Choose "Save Frame As" from the "File" menu, type a name for your file, and choose a destination.
- Choose a file format from the "Format" pop-up menu:
- Choose Macintosh "PICT" File if you intend to use the resulting still image in an iMovie movie.
- Choose "JPEG" if you intend to email the picture or post it on the Web.
- Click "Save."
Video takes up enormous amounts of hard drive space. One minute of DV footage uses approximately 220 megabytes (MB) of disk space. Five minutes of video takes up approximately 1 gigabyte (GB). Editing a large movie will quickly use up disk space.
You will need to monitor your disk space during importing and editing.
The Free Space status bar shows how much disk space is currently in use:
- Green indicates more than 400 MB is available on your hard drive (enough to import safely).
- Yellow is an early warning indicating there is less than 400 MB of space remaining on the disk (just under 2 minutes of video).
- Red indicates that less than 200 MB of space (about 1 minute of video) remains on the disk.
Don't let the status bar go below 100 MB.
When you get low on disk space, you can and should empty the trash which gets rid of all the discarded clips which can add up to substantial disk space. You might also remove any other unused files on the shelf.
You can delete unused clips by selecting them and pressing the Delete key or by dragging them to the iMovie Trash can. The iMovie Trash can also contains excess footage trimmed off clips and any other elements deleted from your project.
To free up hard drive space, choose "Empty Trash" from the "File" menu. This permanently deletes any unused files from your project and your hard disk. Once emptied, you will not be able to undo any previous changes or retrieve clips.
You can view you movie in the view monitor or view it in full screen. In iMovie, you can watch a movie in full-screen mode at any time by clicking the "Play Full Screen" button.
To stop playing a movie in full-screen mode - Click the movie.
Import only what you think
you'll need:
Because imported video takes up so much
disk space, focus on importing only the scenes you think you'll use.
iMovie makes it easy to monitor your available disk space
while importing.
Use the easiest way to import
only what you need:
Use the iMovie playback controls to
rewind the tape to a few seconds before the point where you want to
start importing. Then, click Play and press the Space Bar when you
see what you want. To stop importing, press the Space Bar
again.
Import with "scene detection"
if you intend to add transitions between scenes:
Take advantage of the "Automatically
start new clip at scene break" feature, which you can turn on in
the Import panel of the Preferences dialog box. This way, you won't
have to look for the scene changes because the clips will already be
divided that way.
To keep audio and video
synchronized:
Add audio to the movie after the video editing is complete. If you do
add video prior to completion of video editing, you can the audio to
specific video.
To use all of the audio, but
replace part of the video in a clip:
You can use the "Paste Over" command to replace video while
keeping the audio that is included in the video.
To avoid running out of memory
when applying changes to several clips at
once:
Increase the amount of memory allocated to iMovie. To do this,
select the iMovie application icon and choose "Get
Info" from the "File" menu. Enter a larger number in the
Preferred Size box.
