Working with iDVD Projects

If iDVD is currently running because you

shared a movie from GarageBand, you don’t

need to open, create, or save your project—

it’s all done for you. If you just launched iDVD

independently, you can create a new project

or open an existing project from the File

menu; doing so closes the current project

(only one project can be open at a time).

The iDVD project ﬁle

The iDVD project ﬁle appears by default in

your Docu ments folder (within your Home

folder), and ends in the extension “.dvdproj”.

iDVD stores all of its related ﬁles in the

project ﬁle itself, which is a package.

4 Tips

n Many of the newest Mac models sport

Super Drives that burn dual-layer DVD

media, which can store up to 8.5 GB of

data and hold around three hours of

video footage.

n Make sure you have plenty of free hard

disk space available—at least 10 to 20 GB.

n Storing the project ﬁle in the Documents

folder may be ﬁne for casual use, but

an iDVD project may not ﬁt on your

startup disk. When traveling, I move the

project ﬁle to another partition of my

PowerBook’s hard disk, or ofﬂoad every-

thing to a speedy external drive.

n If you do move your iDVD project, make

sure it can still locate your original iMovie

project and its media ﬁles. If iDVD gets

confused, it warns you with a dialog

(Figure 1.1). Select a ﬁle from the list and

click Find File if the ﬁle is actually avail-

able somewhere else, or click Cancel to

proceed. You can still work on the project

if you cancel, but you’ll get a broken link

warning if you play any of the footage.

Using iDVD on

Non-SuperDrive Macs

You can run iDVD on a Mac that does not

include a SuperDrive, then archive your

project or save it to a disc image for burn-

ing on another computer (see Chapter 5).

Figure 1.1 If iDVD cannot locate the media ﬁles used

in your project, it displays this dialog.

DVD Disc Speeds

DVD discs are marked as being 1x, 2x, 4x,

or 8x speed. The SuperDrive that comes

in the current iMac, for example, writes

data at 8x speed, which means the laser

that carves into the disc’s surface is fast

enough to keep up with a faster-spinning

disc. All recent SuperDrives can write to

higher-speed media, even if they’re not

4x- or 8x-speed drives, at 1x or 2x speed.

Working with iDVD Projects

Switch Between NTSC and PAL

Choose Project Info from the Project

menu, and change the Video Mode setting

at any time. Also, in iDVD’s preferences

you’ll ﬁnd a Video Mode setting in the

Projects area that applies to new projects.
