Transcribe a BigBlueButton recording to text.

A BigBlueButton recording is usually a playback page, not a file. Where your server offers the video format, download the MP4; where it does not, here is what works instead.

The file you have

What a BigBlueButton recording is.

Default format
A 'presentation' playback page that reassembles slides, audio and chat in the browser. There is no single file to download.
Video format
Servers with the video recording format enabled list an MP4 next to the recording. That file uploads as it is.
No MP4 offered
Ask the administrator to enable the video format, or play the recording and capture it with a screen recorder that records system sound.
Inside Moodle
Recordings are listed in the BigBlueButton activity; the available formats appear beside each one.

There is no link to paste for this one. A playback link is a web application, not a media file, so it cannot be fetched. Use the MP4 if your server provides one.

How it works

Three steps, the first one is the only one that takes any thought.

1

Check for a video format

In the recordings list, look for 'video' beside the recording and download the MP4.

2

Otherwise, capture the playback

Record it with a screen recorder with system sound on; see the screen-recording pages linked below.

3

Upload the file

The class comes back as timestamped text with chapters.

Good to know

What trips people up, and what to do about it.

Example. A language school's Moodle lists a 90-minute class with a video format. The 350 MB MP4 is downloaded and transcribed in about three minutes, and students get the DOCX as lesson notes.

What comes back

More than a wall of text.

The same four things for every BigBlueButton recording, whatever its length.

A transcript with timestamps

Every line carries its time. Click a line to hear that second again, or search a name or phrase and jump to each place it was said.

A summary, chapters and key quotes

A brief with the takeaways, chapters with their start times, and the quotes worth keeping. Speakers are identified and named in the summary, key quotes and chapters.

Questions answered from the recording

Ask where a topic came up or what was decided, and get the answer with the time it was said, instead of scrolling the whole text.

Every export

TXT, DOCX, SRT, VTT, JSON from the same transcript: a document to edit, caption files for video, plain text to paste, structured data for your own tools.

Pricing

Free preview. Packs from $4, and the minutes never expire.

FAQ

BigBlueButton to text, answered.

How do I download a BigBlueButton recording?

If your server has the video recording format enabled, an MP4 is listed beside the recording. If only 'presentation' is listed, there is no file; ask the administrator or capture the playback with a screen recorder.

Can I paste the playback link?

No. The playback is a web page that plays several streams together, not a media file a link can fetch.

What does transcribing BigBlueButton recordings cost?

The preview and the summary are free. A pack opens the full transcript: $4 for 500 minutes, $8 for 1,000 minutes, $12 for 2,000 minutes, $24 for 5,000 minutes. Packs are one-time, credits never expire, and Workspace is $19 a month if you transcribe every week.

How long can the recording be?

One file can run up to 10 hours or 5 GB. The box on this page takes files up to 500 MB; a larger file continues on the main upload page, which uploads it in parts. Most recordings come back in about two minutes per hour of audio.

Is the recording kept private?

Recordings are transcribed on our own servers and are never used for training. You can delete a recording and its transcript at any time.
