Losing First Caption
When you export a DV movie with closed captions you should specify the lower limit for the
closed caption data. This is necessary due to the way closed captions are combined with the DV
movie.
For example, if you are using pop-on captions and your actual movie content time code starts at
1:00:00:00 and the first closed caption appears one second into the movie at 1:00:01:00 the
closed caption data is placed into the DV movie before the caption is scheduled to pop on . By
setting Lower Limit to 1:00:00:00 you force MacCaption to begin putting the closed caption data
into movie no earlier than time code 1:00:00:00.
This issue is extremely important when you caption a commercial spot. If you do not set a lower
Limit within the actual video content area, you may lose the first caption when the beginning of
the video is edited out later.
