Extra Bits | Making a Movie in iMovie HD and iDVD 5: Visual QuickProject Guide

When sharing just a range of clips, the selection must be contiguousthey all need to connect to each other. Otherwise, the "Share selected clips only" option is disabled.
You can share video clips that are on the Shelf, too. If you select more than one, iMovie assembles them in the order they were originally imported, not their order on the Shelf.

iMovie warns you if the movie's expected file size is too large to send via email. Look in the summary below the file name field.
Be a responsible Internet citizen: refrain from sending large files (2 MB or larger) via email. A copy of the movie must be stored on every email server between you and your recipient's computer; combined with spam and malicious email attachments floating around out there, this puts a strain on Internet service providers, who may in turn restrict your capability to successfully send large attachments.

If you're not a .Mac member, go to www.mac.com to sign up. A one-year membership costs $100, but you can try the service free for 60 days. (Even if you don't choose to pay, you get to keep your .Mac screen name, which is used by iChat AV.)
At this writing, the .Mac service includes 125 MB of hard disk space. If you find yourself filling that up with movies (or photos or other files), Apple is happy to sell you more spaceup to 1 GB of storage (at $50 per year).
iMovie reads your .Mac membership information when it launches. If you want to publish to another person's account, you need to quit iMovie, make the change in the .Mac pane of the Mac OS X System Preferences, and then relaunch iMovie.
You can also publish movies to a .Mac HomePage without doing it directly from iMovie (if you've created a QuickTime movie using custom settings). Copy the movie file to your iDisk, log on to .Mac, click the HomePage icon, and follow the instructions.

iMovie's default QuickTime settings offer decent image quality and file sizes, but you can do better. Choose Expert Settings from the popup menu, then specify another type of video compression, such as Sorenson Video 3. Apple has more information on its support Web site: http://docs.info.apple.com/article.html?artnum=165371.
You'll notice that the frame size for Full Quality DV is 720 x 480 pixels, which is a wider screen size than the Monitor's size of 640 x 480. What's going on?
Although each frame is made up of pixels, the pixels in video are rectangular, not square (taller than they are wide). When you view it in iMovie or iDVD, the size is converted to prevent video from looking squished.

Clicking a chapter marker in the iDVD pane moves the Playhead to that point in the Timeline.
You can't move chapter markers. Instead, select a marker in the iDVD pane, click the Remove Chapter button, and then create a new marker in the new location.
Instead of going to the iDVD pane, use the Add Chapter Marker (or press ) or Delete Chapter Marker () items in the Advanced menu.
Another way to share is to record your movie back to a MiniDV tape in your camcorder, using the Videocamera option in the Share dialog. If you aren't able to burn DVDs, you can connect your camcorder to your television to view the movie.
If your Mac supports Bluetooth (a short-range wireless network protocol) and you own a Blue-tooth-enabled cellular phone, you can share your movie via Bluetooth in the Share dialog.
