Differences in behavior between markings and subtitles

The following differences exist in the specifications and behavior of video markings and video subtitles.

Markings

This feature allows you to add diagrams or text to areas of a video that you want viewers to pay attention to.
The video will pause for the specified number of seconds at the point where a marking is placed.

Subtitles

This feature displays text based on the audio in the video or any additional descriptions as subtitles.
The video will not pause while subtitles are being displayed.

Certain edits cannot be made due to differences in behavior

Because the video is paused while a marking is displayed, subtitles cannot start or end during the pause period.
When displaying a marking and subtitles at the same time, please edit so that the marking display (pause period) falls within the subtitle display period.

Edits that cannot be made

The following types of edits cannot be made.
Adjust the marking's pause duration or the subtitle's display time and edit as shown in the "Edits that can be made" examples described below.

  • Setting the marking's pause period to extend beyond the point where the subtitle ends
  • Starting subtitle display while the video is paused due to a marking

Subtitles may be deleted when a marking is deleted

If you delete a marking while it overlaps with a subtitle, the marking's pause period is removed,
and any subtitles displayed during that period will be deleted at the same time.

If you want to keep the subtitle, extend the subtitle's display time beyond the marking's pause period before deleting the marking.

If the marking's pause period and the subtitle's display time are identical, the subtitle will not be retained

If the subtitle's display time is longer than the marking's pause period, only the portion of the subtitle that does not overlap with the marking will be retained
