Use the generated captions as a draft for video editing, dialogue replacement, voice-over notes, or a SceneDub dubbing session. For a dedicated SubRip export flow, use the SRT generator.
What does Subtitle generator do?
Generate a draft subtitle track from English audio or video, then export SRT or WebVTT. SceneDub creates separate caption files; it does not burn text into your video. Review cue timing and wording in the destination editor before publishing.
