How Subtitles Are Positioned
When you import subtitles, they are positioned in the subtitle stream based on the start
and end timecode values in the subtitle file and the video stream’s asset timecode. This
means that the timecode values in the subtitle file must be relative to the asset timecode
of the video stream’s clip, not to the timeline’s zero-based timecode. An exception is
when you use an STL format subtitle file, which can choose to use the timeline’s zero-based
timecode. See
Timeline Command
for information on positioning subtitles when using
an STL format file. See
Understanding Time Information in the Track Editor
for more
information on asset-based versus zero-based timecode.
