Add subtitles to a video

Burned-in subtitles are part of the picture, so they show on every app — useful for Shorts and silent autoplay. Auto timing splits the script into short lines and spreads them by length; it is a draft, not speech recognition. You can download it as .srt, fix the timing and upload it again. Chinese and Japanese fonts are supported.

Subtitles sit inside a safe area away from the edges, where app buttons usually are.

Frequently asked questions

Is the auto timing accurate?

No — it is spread by text length, not synced to speech. Use it as a draft or upload an exact SRT file.

Can viewers turn the subtitles off?

No. Burned-in subtitles are part of the video. Upload a separate .srt file to platforms if you want switchable captions.

Is my video uploaded?

No.
