Creating a movie to use with iDVD, iWeb, or other Apple applications
If you want to use of your iMovie projects in iDVD, iWeb, or another Apple application, you need to render it and send it to the Media Browser. iMovie allows you to render one or more sizes of your a movie, depending on the size of the original media used in the project.
If the larger sizes are not available, the original project media isnt large enough to render in that size. The largest media size used in the project determines the final movie sizes you can render.

To share your project with other applications through the Media Browser:
Select it in the Project Library, and then choose Share > Media Browser.
Select the size that best matches what youll be using the video for. For iDVD, the Large size is best.
Click Share.
Rendering can take up to several minutes depending on the size of your movie. It will also take longer if you render more than one movie size at once.
Open iDVD or your other application and then look for the rendered movies in the Movies window or iLife Media Browser.
For best results in iDVD, select the largest movie thats available.
In iMovie, an icon appears next to the projects name in the Project Library to indicate that the project has been rendered.
If you make further edits to your project in iMovie after youve rendered it, the title bar indicates that your project is out of date and needs to be rendered again. The old versions of the movie are deleted and replaced by new ones when you render it again.
If you want to save the previous version of your movie before you edit it, you can do so by exporting it to the Finder.
