For more on the importing files, see "Importing Bitmaps," page 357 , in Chapter 16, "Working with Vector Graphics and Bitmaps."
The Video Import wizard (File, Import) not only makes it easier to get video into your project, it helps you perform editing tasks such as trimming the clip, creating multiple clips, and reordering clips.
