Editing Imported Subtitles
Once you have imported a subtitle file, you can work with the individual subtitle clips as
if you had manually created them. You can reposition them and change their color
mapping and any other subtitle attribute. If you imported the subtitles as text from a
single subtitle file, you can edit the text. If you imported a group of graphics files as your
subtitles, you cannot edit the actual text.
You can also modify all of the subtitles in a stream by using the Apply to Stream controls.
