Once a video is finished (a finished version is in the project folder; Finished_Project11.mov), it can be distributed for the enjoyment of others and the deep satisfaction of the creator. iMovie provides a number of avenues of distribution, but before turning your attention to sharing, you should explore the most important output option availablecreating an archive.
Unlike music, video is remarkably large relative to typical hard-disk storage capacity. At 5 minutes of video per gigabyte, finished video in even a small collection can overwhelm a typical Mac. Consequently, archiving video is imperative. While it's great to be able to burn DVDs and CD-ROMs, put videos on the Internet, and even email them, all of these methods are for distributionthey take the high quality of your digital video and squeeze it down to fit into a given format. The quality of a true archive needs to be as high as you can manage; the perfect archive for your videos is back in the digital videotape format from which they came.
Ideally, you'll have a special videocassette allocated for only finished videos, so they don't get taped over or lost among the hours of video you shoot. Lesson 8 mentions some specifics for organizing and labeling tapes, but for now let's just say you have a master cassette onto which you plan to record your video before you remove it from your Mac.
The process of getting video from iMovie to your camcorder is straightforward.
If you are serious about your video work, it is often a good idea to save an additional copy of your video without music. Delete the music track, and make a recording to your DV tape. Then you can undo the music deletion and save your project with it there. The point of having a version without music is simply that once the music and the rest of the video are merged together on tape, they are harder to separate should you ever want to reedit the video (making it shorter, for instance, or combining parts with other videos to make longer movies), or if one day you decide the music is wrong for the project. For many reasons, it can be a good practice for advanced users.
Now that a copy of your video is in DV format and is safely back on tape, you can output other formats of your video for distribution. Eventually, you can delete the project and media from your computer, knowing that if you need to you can bring the project back into your Mac for new output options or a little reediting.
