The Essentials of Movie Making

Editing video is one of the most complex tasks you will perform in iLife. Not that it's technically difficultiMovie HD, FireWire, and the latest video formats have made it easier than ever.

But editing video can be time consuming and labor intensive. Bringing media into iMovie HD, fine-tuning the length of clips, timing shots to match a music track, adding transitions and effectsit all takes time. But as a creative exercise, video editing is hard to beat.

If you're new to video editing, start small. Create a short moviebetween 30 and 90 seconds. Try your hand at a simple music video: some video, some still photos from iPhoto, and a music soundtrack from iTunes. Your first effort shouldn't be an epic; it should be a short story, or even a single well-wrought paragraph. That's the best way to learn the art and science of editingand to appreciate its magic.

Video Editing: The Big Picture

Import Assets

Bring in video from a camcorder and, optionally, add photos and music from iTunes.

Trim the Fat

Use iMovie HD's crop markers and Crop command to discard unwanted portions of clips.

Sequence Clips

Drag clips to the timeline viewer and clip viewer to add them to your final movie. Trim clips as needed to fine-tune their length.

Polish

If you've added music or other audio tracks, you'll want to fine-tune audio levels for each track.

Add Eye Candy

Create transitions between clips, and add titles and any special effects.

Export

Record your movie back to tape, send it to iDVD, GarageBand, or iWeb; or export it as a QuickTime movie for playback on an iPod or other device.
