QuickTime 123
Custom Still Fallbacks
An even better still-image fallback can be produced by generating a custom still image from the
movie itself and using the watermark feature to superimpose a text message on this fallback
image.
Create your own QTIF setting. Choose Photo-JPEG for the codec and use the watermark feature
in the Image tab to composite a text message. For more details on using the watermark feature,
see “Watermark” on page 70.
To choose which frame becomes the image, open the Project window of the movie, drag the
slider to the desired frame, then close the Project window.
Using Text as a Fallback
Sometimes you may simply want to have a text message displayed to viewers who do not have
the needed software installed. You can manually create a still image containing the text
message with your favorite image editor and use this still as the fallback as described in the
previous section.
On Windows, you cannot use a QuickTime text track as a fallback because text tracks are not
fully supported under older versions of QuickTime for Windows.
Using Preferences to Ensure Fallbacks
To make sure you always have a fallback, you can set a global preference to set a text message
or picture as the fallback.
The Preferences dialog has several different options for automatically generating fallbacks. the
options are:
• Use image as needed
• Use text as needed
• Always use image
•
Always use text
• None
Set this preference to Use image as needed or Use text as needed. If no alternate in a movie is
compatible with QuickTime 3, then Cleaner automatically adds a text message or image as the
fallback. You can specify this text or image with the Set button in the Preferences dialog. By
default, Cleaner contains a simple text message as a global fallback.
