How-to: Subtitles¶
ClipPulse AI generates OpusClip-style animated subtitles using the ASS format.
Editing captions¶
- After clips are generated, open a clip in the browser editor.
- Click the caption text to edit the words.
- Save — the ASS file is regenerated and the clip re-rendered.
Style notes¶
- Word-by-word highlight: the current word is colored; others stay neutral.
- Smart wrapping:
WrapStyle=1keeps long lines inside the 9:16 frame. - Position: subtitles sit in the lower third to avoid covering faces.
