How to turn a video lecture into exam-ready notes
Two hours of video are impossible to skim the night before an exam. Convert them into searchable, structured notes instead.
Recorded lectures are the richest study material you have — and the least usable. Two hours of video are impossible to skim the night before an exam, and scrubbing back to find the one slide you needed wastes the little time you have. The fix is to convert the lecture into structured text you can search, highlight and quiz yourself on.
This guide walks through the exact workflow, from a raw screen recording or phone video to a clean set of study notes and a mind map — in minutes, and without the video ever leaving your device.
The workflow, step by step
- 1
Drop the video into the dashboard
Add the lecture file (mp4, mov, or a .webm screen recording). The audio track is extracted directly in your browser — the video itself never leaves your device — and only a small audio file is uploaded for transcription.
- 2
Get a speaker-labelled transcript
Aurora transcribes with automatic language detection and speaker diarization, so a Q&A session reads like a script: who asked what, and how the professor answered.
- 3
Generate structured Study Notes
From the transcript, generate Study Notes — hierarchical bullets with every key term in bold — so the lecture becomes skimmable and searchable.
- 4
Add a Mind Map for the big picture
Generate a Mind Map to see how the topics connect. Use it right after the first read and again the day before the exam.
Why transcription beats re-watching
Re-watching a lecture is passive and slow: you sit through the parts you already know to reach the three minutes you did not. A transcript flips that. You skim, use Ctrl-F to jump to a term, and read only what matters — turning a two-hour rewatch into a fifteen-minute review.
Text is also the input every other study tool needs. Once the lecture is a transcript, you can summarise it, map it, turn it into flashcards, or ask an AI tutor about it. Video is a dead end; text is a starting point.
Keep the full lecture, minus the filler
Sometimes you want the complete lecture verbatim, not a summary. Use the "Clean Text" view: it keeps every sentence but removes the "ehm"s, false starts and repetitions, and formats the result into readable paragraphs with the speaker labels preserved.
This is the version to export to DOCX or Markdown when you want a permanent, shareable record of the lecture that reads like a well-edited transcript rather than raw dictation.
Frequently asked questions
Does my video get uploaded to the cloud?
No. The audio track is extracted locally in your browser and only that small audio file is sent for transcription. The video file never leaves your device, and source files are deleted after processing.
What video formats are supported?
Common formats including mp4, mov and webm screen recordings. Audio-only files (such as m4a voice memos) work too.
Can it handle lectures in other languages?
Yes. Transcription auto-detects the language and supports multilingual lectures, including code-switching between languages within the same recording.
