Lecture Recording to Video Lecture

How lecture to video works

This tool starts where most lectures end: with a long recording you don't want to rewatch in full. Drop a class capture, a Zoom export, an OBS screen-record, or a phone audio file into Scholarly and the AI transcribes the entire session first. With a complete transcript in hand, it identifies the actual lesson — the definitions, the worked examples, the slides that got the most airtime — and separates them from the tangents, the housekeeping, the questions that went nowhere, and the silence at the start while the professor set up.

The AI then writes a new narration that follows the lecture's argument but in a tighter form, and re-renders the result as a video summary with chapters, on-screen visual aids, and the original moments-of-truth pulled forward. You end up with a watchable 10–20 minute lecture from a recording that was twice as long, with nothing important left out.

Why convert a lecture recording to video lecture

Lecture recordings are the worst study object in your library. They're long, they're chronological, and they have no chapter markers, so finding the five minutes where the professor explained the thing you need is a chore. Scrubbing through a 90-minute MP4 looking for one definition is the single biggest reason students give up on reviewing recorded classes at all.

A re-edited video lecture fixes every part of that. The narration is tighter, the chapters let you jump straight to the section you need, the transcript is fully searchable, and the on-screen highlights mean the bits that mattered are also the bits that look different. The recording you would have skipped becomes the recording you actually open before the exam.

Supported formats

Upload almost any audio or video format. MP4, MOV, MKV, WebM, and AVI work for video. MP3, M4A, WAV, AAC, OGG, and FLAC work for audio. Zoom cloud recordings (the MP4 you get from Zoom's "download recording" link) and OBS screen-recordings drop in as-is. Phone-recorded class audio works — Scholarly is fine with background noise, microphone distance, and multi-speaker discussions.

The AI handles long files. A two-hour seminar, a three-hour lab walkthrough, or a full half-day workshop will all be transcribed in one pass and summarized in a single video. If your lecture used slides shared on screen, the AI extracts the slide content from the video frames and surfaces it in the re-edited output alongside the narration.

From lecture to flashcards to video

Once the re-edited video is rendered, Scholarly treats it as a study object you can drill further. One click extracts the definitions, equations, and worked examples mentioned in the lecture and turns them into spaced-repetition flashcards. Another click generates a practice quiz from the same content. The AI chat sidebar can answer questions about anything the professor said, with timestamps that link straight back to the moment in the recording.

This pipeline — recording → video summary → flashcards → quiz — closes the loop between sitting in class and studying for the exam. The lecture stops being a 90-minute artifact you can't review and becomes a layered study object that you can drop into a 20-minute review block.

Share with your study group

The re-edited lecture can be shared with classmates from a single link. If someone in the group missed class or couldn't follow the recording, the shared video gives them the same summary, chapter markers, and transcript everyone else has. AI chat stays available on the shared link, so each person can ask their own follow-up questions without having to bring them to the next group meeting.
