Apple iMovie HD - Manual (Page 78)

78 Chapter 10 Sharing Your Finished Movie
4 Type a name for your movie file and select a destination.
5 Click Save.
iMovie HD takes a little while to compress and save your movie. It’s best not to use your
computer for other tasks during the export process. How long it takes depends
primarily on how long your movie is, but also on how small the final movie file will be.
Smaller movie files take longer to compress.
The exported movie is a QuickTime file. To watch the movie on your computer screen,
double-click the movie file in the Finder.
Note: If you create a QuickTime movie using the Full Quality option, iMovie HD does
not export chapter markers or chapter titles in the movie.
QuickTime Expert Export Settings
If one of the preset export options doesn’t work for you, you can experiment with your
own QuickTime compression settings to get video output that’s best suited for your
needs.
To apply your own compression settings:
1 Choose File > Share.
2 Click QuickTime in the toolbar.
3 Choose Expert Settings from the “Compress movie for” pop-up menu.
4 Click Share.
5 Choose the type of export format you want and click Options.
Here are a few guidelines to keep in mind as you experiment with your own
compression settings:
• MPEG-4 is the current standard codec (or compression/decompression format) used
for movies that will be viewed on the web.
• For movies that will be viewed on older Windows computer systems, you may want
to use the Motion JPEG codec.
• For a high-quality movie, you can export your movie in the Sorenson Video codec.
This format reduces the file size of the movie while retaining relatively high quality.
• In general, choose settings that give you the best tradeoff between file size and
video playback quality.
• Pick your desired movie frame size first. Frame size is the primary determiner of the
movie file size.
