Export Bilibili subtitles to SRT, in English or bilingual
Open the video on bilibili.com, click WT on the player and start: WatchTranslate writes subtitles from the speech, or translates the uploader's track. Then open the Export tab, pick Bilingual, Original or Target only and SRT or WebVTT, and your browser saves the file.

Bilibili subtitles to an SRT file in three steps
Open the video and click WT
Chrome or Edge on a computer with WatchTranslate added. Signing in to Bilibili is not needed for subtitles made from the speech.
WTIt grows in mud, yet its flower is clean.Start, and let it play
Pick your Target language and start. Lines appear as the video plays; only the parts you play, or prepare in advance, go into the file.
Open WT, then Export
Export is the third tab in the WT panel. Choose Content (Bilingual) and Format (SRT), then Export subtitles: the browser saves a .srt or .vtt file.
What the exported file gives you
SRT or WebVTT
Numbered cues with start and end times, ready for video players, editors and subtitle tools.
Original, translation or both
Bilingual puts your language and the Chinese sentence in the same cue, one line each, in your display order.
Works without a CC track
Audio recognition writes the subtitles from the speech, so a video with no subtitle track still gives you a file.
Why people save Bilibili subtitles as a file
Studying Chinese
A bilingual SRT puts each Mandarin sentence next to its meaning, to read again away from the video.
Notes and quotes
Copy what a lecturer or explainer said, with the time it was said.
Your own player
Load the SRT next to a copy of the video you are allowed to keep, in VLC or another player.
Editing and checking
Open the file in a subtitle editor to fix names or timing before you reuse it.
Sharing a translation
Send a friend the English lines of a Chinese video they cannot follow.
Keeping a record
Save what a video said in case the upload changes or is taken down.
Bilingual, Original or Target only
The Export tab's Content menu sets what goes into each cue. All three come from the same lines you saw on the player.
| Export content | What each cue holds | Good for |
|---|---|---|
| Bilingual | Your language and the Chinese sentence, one line each | Learning Chinese, checking a translation |
| Target only | Only your language | Watching in a player, sharing the English |
| Original | Only the Chinese, as recognised from the speech or read from the track | Chinese text of a video with no track |

What we exported from Bilibili
On a computer with the live extension, signed out of Bilibili, on a Mandarin science short about lotus plants.
- Works
Chinese science short · bilingual SRT
Subtitle source was Audio recognition, target English. Export with Bilingual and SRT saved a 25-cue file covering 0:00–1:56, the part that already had subtitles.

Cues from the SRT we exported

| 00:00:00,320 --> 00:00:03,400 | The lotus stem isn't called a stem; it's called a lotus root. | 荷花的茎不叫茎，叫做藕。 |
| 00:00:08,760 --> 00:00:13,289 | Between two root segments, the place where roots and buds grow is called a node. | 两段藕之间，生根长芽的地方叫做节。 |

What goes into an exported Bilibili SRT
WatchTranslate does not download a file Bilibili already has. It makes the subtitles itself, from the speech with Audio recognition or from the uploader's track with Video subtitles, and the Export tab writes those lines to a file. The file holds only the stretches that already have subtitles; the hint under the button says which time ranges it covers.
Whole video in one file
Play the video to the end, or use Translate all subtitles in advance before you export, so every part is covered.
Danmaku stays out
Bullet comments are not subtitles and are never written to the file; only the lines from the speech or the track are.
Subtitles only, not the video
Export saves a text file of timed lines. The video itself stays on Bilibili.
Where the exported lines come from
From the speech
The video is handled in stretches of about 30 seconds: speech is recognised in its own language, then translated with the sentences around it in view.
From an uploader track
Signed in to Bilibili, WatchTranslate reads the track your browser can see and translates its lines, keeping their timing.
What it costs
Exporting subtitles your own account generated is free. Parts someone else's viewing generated cost 0.1 points a minute, and the button shows the price before anything is charged.
Tips for a clean SRT from Bilibili
Prepare long videos
Translate all subtitles in advance covers a lecture or long video before you export.
Same settings as you watched
The file follows the subtitle source and target language that were on when the lines were made.
SRT for players, VTT for the web
Most desktop players and editors read SRT; WebVTT suits players on web pages.
Bilibili subtitle export questions
Can I export Bilibili subtitles to SRT?
Yes. Make subtitles on bilibili.com with WatchTranslate, then open the Export tab and choose SRT or WebVTT.
Can I get English SRT subtitles for a Chinese Bilibili video?
Yes. Set the Target language to English and export Target only, or Bilingual for English and Chinese together.
What if the Bilibili video has no CC subtitles?
Use Audio recognition: the subtitles are written from the speech, and you export them the same way.
Does it download Bilibili's own subtitle file?
No. It exports the subtitles WatchTranslate made for the video, from the speech or translated from the uploader's track.
Does it download the video?
No. Export saves a subtitle file of timed lines; the video stays on Bilibili.
Why does my SRT not cover the whole video?
The file holds only the parts that already have subtitles. Play to the end, or use Translate all subtitles in advance, then export.
Is exporting free?
Exporting subtitles your own account generated is free. Parts generated by someone else's viewing cost 0.1 points a minute, shown before you confirm.
Are danmaku comments in the file?
No. Only the subtitle lines are exported, not bullet comments.
Do I need a Bilibili account?
Not for Audio recognition; we tested signed out. Reading an uploader's track needs a Bilibili sign-in.
