Setting the Frame Duration of a Text Track
You can set the duration of each frame in an existing text track to a value other than 2 seconds. To do so, you export the track, make changes, then reimport the track.
To change the current text frame information:
- In QuickTime Player, choose File > Export and choose "Text to Text" from the Export pop-up menu.
- Click Options and select "Show Text, Descriptors, and Time."
- Edit the information in the text file and then import the track back into the movie.
The duration for each line of text in the text file appears on a separate line before the line of text. The time you type is the length of time after the movie has started at which this line of text will appear.
Timestamps are specified as hours:minutes:seconds:fractions of a second (the default Text to Text export setting is 1/600th of a second). For example, if you enter the time 00:02:11:00, the text on the following line appears at 2 minutes and 11 seconds into the movie.
For information about the other text track descriptors, see the developer section of the QuickTime website at www.apple.com/quicktime/.
