36 Chapter 4 Bringing Video Into iMovie HD

Did You Know? — About Video Formats and Frame Rates

When you create a new project, you can specify whether the project is for standard

definition DV, high definition, DV widescreen, MPEG-4 video, or the format for an

iSight camera.

iMovie supports the following video formats:

• DV NTSC

• DV PAL

• DV NTSC Widescreen

• DV PAL Widescreen

• MPEG-4

• iSight

• HDV 720p

• HDV 1080i

In most cases, you don’t need to specify anything for your video format. iMovie HD

is preset to import standard definition digital video (DV), and it can automatically

detect whether you have connected a high definition video camera or an Apple

iSight camera and switch your project to the appropriate settings. However, with

standard video formats, you may at times want to specify a particular format, such

as DV widescreen.

To specify a video format for a new project, choose File > New Project or click the

Create a New Project button in the iMovie HD project window. In the Create Project

dialog, click the “Video format” triangle to display format options. Choose the video

format options you want.

Different video formats use different frame rates. Most video formats, including

standard definition, high definition, and widescreen, use either 29.97 frames per

second or 25 frames per second. For example, NTSC (National Television Standards

Committee) and PAL (Phase Alternating Line) are two common digital video (DV)

formats. NTSC format, which is used in North America and Japan, has a frame rate of

29.97 frames per second (fps). PAL format, which is used in most of the world outside

North America, has a frame rate of 25 fps. When you first import video into a project,

iMovie HD automatically detects the correct frame rate of the incoming footage.
