Chapter 4 Exporting Files with QuickTime Pro 49

4 Choose a poster frame option for the movie.

The poster frame determines the still image viewers will see when they load the web

page with the embedded reference movie. If you want to set a new poster frame

before exporting the versions, click Cancel. Then navigate to the frame you want to use

and choose View > Set Poster Frame.

5 Click Export to create the files necessary for the options you selected.

The exporting process creates several files, including files for each version of the movie

you select, a reference movie that will automatically deliver the correct version to the

viewer, and an HTML file that contains a snippet of code you can use to embed the

movie in a web page. All of these files must be copied to your web server, in the same

location relative to each other and with the same file names, in order for the reference

movie and HTML snippet to function correctly.

Exporting MPEG-4 Files

MPEG-4 is the latest worldwide industry standard for delivering professional-quality

audio and video over a wide range of bandwidths, from mobile multimedia to high

definition. When you want to create a file that will work with another MPEG-4 device,

use QuickTime Pro to create MPEG-4 content by exporting a movie.

To export a file to the MPEG-4 format:

1 Open the movie you want to export in QuickTime Player, then choose File > Export.

2 Choose “Movie to MPEG-4” from the Export pop-up menu.

Note: To create an MPEG-4 movie that is optimized for use with Apple TV, iPhone, or

iPod, select “Movie to Apple TV” , “Movie to iPhone”, or “Movie to iPod” from the Export

pop-up menu. All of the MPEG-4 options will be set to the appropriate values for you.

To adjust settings such as file format, compression, and distribution restrictions, click

Options. The options you choose depend on the network over which you’ll deliver the

file and the viewers’ connection. The following sections describe the options in detail.

MPEG-4 Video Export Options

When you export a movie to MPEG-4 format (by choosing File > Export and then

choosing “Movie to MPEG-4”), you access the following options by clicking Options and

then clicking Video.

Â File Format: To ensure operability with devices made by ISMA members, choose

“MP4 (ISMA).” For more information, go to www.isma.tv.
