Can it generate subtitles from speech automatically?

You can ask the AI assistant in the editor to listen and turn what it hears into subtitles. That step needs you to sign in — the audio has to go into your TutuDrive for the AI to hear it, and the usage allowance is whatever the assistant shows. Adding lines by hand and importing an SRT need no sign-in.

Can I import an existing SRT?

Yes. Press "Import subtitle file" and choose an .srt (.vtt and .lrc work too). Timings and text come in, and every line stays editable. Lines that overlap in time are placed on separate tracks automatically.

Are subtitles burned in or a separate file?

Either. "Download video" burns the subtitles into the picture so they show everywhere; "Export SRT" above the subtitle list saves a separate subtitle file that players can switch on and off, and that you can send for translation.

How much text fits on one subtitle line?

There is no technical limit, but short lines read best — for Chinese, about 15 characters a line and no more than two lines. Longer than that and viewers move on before they finish reading.

Can I move the subtitles?

Yes, drag them in the preview. New and imported subtitles start towards the bottom of the frame. For vertical video, keep them low but not right at the edge, so the platform's interface does not cover them.

Add subtitles

Add lines one by one or import an SRT — burn them in or export an SRT.

Add subtitles line by line or import an SRT, VTT or LRC file, then style them. Burn them into the video or export an SRT. Free, in your browser, no upload, no watermark.

Subtitles make a video understandable with the sound off — and plenty of people scroll with the sound off.

In the Subtitle panel on the left, press "Add subtitle manually" and a 3-second line appears at the playhead, placed towards the bottom of the frame. Edit the words in the subtitle list, click a line's time to jump there, and drag its ends on the timeline to change how long it stays. If you already have subtitles, press "Import subtitle file" — .srt, .vtt, .lrc and .txt are supported.

Style works as for any text: font, size, colour, outline, background bar and position. Style one line, press "Unify style", and every subtitle follows. The preview and the export use the same text rendering, so what you see is what you get.
