When subtitle narration is turned ON, editing a subtitle here also changes the content of the narration audio automatically to match that subtitle (there is no field for typing text directly into the audio).

If the narration target is "Description," edit the Editing the step title and text instead of the subtitle. To verify or switch the narration target, see Subtitle and text narration.

1. Click [Change] next to Use feature, and check [Subtitles].
   
2. A subtitle is added in the video, and a new subtitle timeline is added to the timeline. By default, the transcribed text from AI analysis is entered.
   
   
3. If there are errors in the transcribed text, edit it. Click the [Pen] button in the video to edit.
   
   

4. You can also add a new subtitle. Jump to the relevant spot in the video, and define a new subtitle with the [＋] button.
   
   

5. You can change when a subtitle is displayed by dragging its subtitle block on the timeline. You can adjust how long it is displayed by dragging its end.
   
   
   

Create subtitles from the step text

If you have already written the step text, you can create subtitles from that text. In the Subtitle list of the video editor, select [From the step text] from [Create subtitles]. If you only have one step, you can also create subtitles from the button in that step's Text pane.

Instead of putting the whole text into one subtitle, the text is split by sentence and assigned to the sections of the step. Because the text is not crammed into one box, the narration is less likely to sound rushed.

The reverse is also possible: you can transcribe the text of subtitles and shapes into the step text all at once. Whether you start from the video side or the text side, you can get both lined up.

If there are already subtitles in the same section, a confirmation appears asking whether to keep the existing subtitles or replace them.

Check subtitles that are read too fast

The narration speed of a subtitle is adjusted to fit within the length (box) in which the subtitle is displayed. If there is a still shape during that time, the still time is also used for narration. For subtitles whose text is long for the box, the Subtitle list shows "Fast ○x". If there are no fast subtitles, a message saying so is displayed.

The multiplier shown is the speed when the still time of shapes is also used for narration. Subtitles that can be read within the still time are not counted as fast.

For subtitles with a mark, split the sentence into shorter parts or leave a gap before the next subtitle (for the last subtitle of a step, extend the end of the subtitle later). This gives a natural speed. For details, see Subtitle narration is too fast to follow in short steps.
