Lecture recording to notes

You get what the lecturer said, word for word as the software heard it, split into paragraphs, each with the time it starts. When someone else talks, a student asking a question for example, they get their own speaker label, as long as the recording picks them up. You do not get a summary, bullet points, flashcards or anything from the slides or the board: it works from the sound only.

With an hour pack, three downloads are made for revising:

• Notes (.txt): every paragraph starts with its timestamp, like the example below.
• Word (.docx): a heading every 10 minutes, so the navigation pane lists the lecture in parts, and a bold timestamp on each paragraph.
• Copy for Notion: the same as Markdown on your clipboard, which Notion turns into headings and paragraphs when you paste.

[00:00] Speaker A: Right, let’s start. Last week we finished with…
[10:14] Speaker A: So why does that matter for the exam question…
[10:52] Speaker B: Is that the same as the second model?
(the format; your lecture’s words go here)

The free tool gives the same text on screen and as .txt, plus .srt and .vtt subtitle files, which also carry a time on every line.

A transcript of a 50-minute lecture is long, often several thousand words, and most of it is the lecturer thinking out loud. Notes are what is left when you take out everything you would not need to read twice. One way to get there:

1. Read it once without writing. With the slides open if you have them. The transcript has the words, the slides have the structure.
2. Mark three things as you go: main points, questions you still have, and the timestamps of anything you did not follow.
3. Replay the marked moments. The timestamp takes you straight there in the recording, so you listen to two minutes, not fifty.
4. Write the notes in your own words. Copying sentences out of the transcript feels productive and mostly is not.
5. End with a short summary, a few lines, and the questions you will ask in the seminar or office hours.

That is close to the Cornell method: a column for cues and questions, a column for notes, and a summary at the bottom. Cornell University’s Learning Strategies Center has a free guide to the Cornell note-taking system, and it points out that writing by hand can help you remember better than just listening or reading. A transcript is not a replacement for that, it is what lets you do it after the lecture instead of during it.

Many students paste a transcript into ChatGPT or another assistant and ask for a summary. Two things to know before you do. Your university and your course decide whether you may use AI tools on course material, and the rules differ from course to course, so check them. And a summary can leave out or change a point without telling you, so keep the timestamps in the text you paste, and check anything you will rely on against the recording.

Check your course’s recording rules and ask the lecturer. Many universities allow recording for your own study, some need permission first, and some lecturers say no. Keep recordings and transcripts to yourself unless the people in them agree. If the lecture is already recorded on Panopto, Echo360, Kaltura or Zoom, see getting the file out of your university’s platform.
