Subtitle Generation: AI Recognizes the Voiceover and Auto-Calibrates the Subtitle Timeline
Date Published
A short video without subtitles gets swiped away the moment viewers scroll past on mute—subtitles are table stakes now. But manual timing is the most tedious step of the workflow: listen to a line, type a line, sync a timestamp. Subtitle Generation hands it to AI: it recognizes the speech in the video, generates subtitles aligned sentence by sentence, calibrates the timeline, and after a quick style template you are ready to export. Subtitles for one video shrink from half an hour to one minute.
วิธีใช้งาน
Import videos
Bring the videos that need subtitles into Subtitle Generation: talking-head clips, finished remixes, and course recordings all work, and batch tasks process several at once.
AI generation and calibration
AI recognizes the speech, generates the subtitle text, and times it automatically at sentence breaks—every subtitle line starts and ends in sync with the voice, with no manual alignment needed.
Apply a style and export
Pick a subtitle style template and adjust font, color, outline, and position (center, bottom, or title-safe). Once it looks right, export—or jump into the timeline for more polish.

คำถามที่พบบ่อย
Does subtitle generation cost points?
AI recognition consumes points based on video duration, as shown in the app; an estimated cost is displayed before generation starts.
How accurate are the generated subtitles?
Clear spoken voiceover reaches high accuracy; for content heavy on proper nouns, a quick proofread after generation is recommended.
Does the timeline need manual adjustment?
AI times subtitles automatically at sentence breaks, and most cases need no adjustment; the odd break can be refined on the timeline.
Which languages are supported?
Chinese, English, and more languages are recognized and turned into matching subtitles; the exact language list follows the app.
Can I customize the subtitle style?
Yes. Font, size, color, outline, and position are all adjustable, and can be saved as templates for reuse.
Can subtitles be exported as a separate file?
Burning subtitles into the exported video is supported; standalone subtitle file export depends on the current app version.
