Exporting iMovie HD to 3G, AVI, MPEG-4, iPod, iPhone, AiFF, etc.

This is a quick guide for people who are new to iMovie. It is about how to use the advanced export mode of iMovie to create/save movies or videos. Of course, you can share your iMovie project via YouTube or Email, but I personally used to save iMovie to video format, because:

* You are only allowed a 100MB file to YouTube. Customizing your settings, you will be able to reduce the size of the file to under that 100MB limit.
* Email applications often limit how large an email you can send. You maybe able to reduce the video to an acceptable size that will allow you to send that video to a friend.
* Well placing video on your website, you realize the bandwidth requirements of a full size DV video is unacceptable from a download time bases for your viewers and the cost of payment to support it. You could keep the image size the same, but reduce other factors to considerably reduce the size of the file while still making a very presentable video.
* You may want to set the video to a different codec (file) type, say for export for another editor.

You may not know that iMovie Expert export allows you to choose many options, such as image codec, size, data bit rate, quality, and audio options too. By altering these options, you can adjust the tradeoffs for the end quality of your movie.

In this article, I will only mention some most commonly used options, hope that it helps. It is up to you to dig deeper and experiment (For another solution to export or convert iMovie project, you could refer to this “Convert iMovie to AVI on Mac” guide).

Creating video or audio in iMovie HD

Open iMovie HD and create a movie, or open an existing movie in the application.
1. File > Export (or Share > QuickTime)
2. Select the “QuickTime” tab.
3. Choose “Exper Settings” from the Compress movie for pop-up menu.
4. click “Share”.

Then a window named “Save exported file as” will show up, you can:
1.Name your movie.
2.choose where to save exported movie.
3.Choose output format from Export pop-up menu, like “Movie to AVI
4.Click “Options” to customize movie settings.
5.Hit “Save” to start the export process.

Depending on the length of your movie, this can take a long time. iMovie uses H.264 compression to create the video file, which will appear on your hard disk in the location you saved it when iMovie is done.

Note: the movie settings give you lots of control for the output video, take MP4 as an example, if you want to create a MP4 video file using iMovie, you could:
1. Select “Movie to MPEG-4” under Export pop-up menu.
2. Click the “Options” button
3. On the MPEG-4 Export popup, under “File Format” select “MP4″  (not the ISMA version)
4. Under “Video Format” select “H.264″
5. Click the “Video Options…” button
6. Under “Encoding Mode” select “Best Quality (Multi-pass)”
7. Click “OK”
8. Under “Image Size” select the best output size  (e.g.  640 x 480 VGA)
9. Under “Data Rate” type in “1600″
10. Under “Optimized for” select “CD/DVD-ROM”
