Lecture recording

Lecture recording refers to the process of recording and archiving the content of a lecture, conference, or seminar.[1] It consists of hardware and software components that work in synergy to record audio and visual components of the lecture.


Hardware is used to capture the lecturer's voice along with the video of the lecturer. Sometimes, the lecturer may use visual aids to support their speech, such as slide shows, which are presented to the audience with some kind of projector. In this case, such slide shows can also be recorded. Once captured, the data is then either stored directly on the capture hardware or sent to a server over a LAN or the Internet. After some processing to adapt the video formats to the desired distribution mechanism, codecs, etc., viewers are then able to remotely access the recording, either in real time or ex post facto.
The recording of a lecture or presentation may use any combination of the tools: Microphone, Camera, Screen capture, Presentation capture, or Document camera.


Software is used both on the capture hardware, the viewer's computer,[2] and the production server. Software ranges from simple web browsers and video players to stand-alone software programs made specifically for viewing lectures.[3][4][5] The viewer's as well as the presenter's software must be compatible with the software on the server which receives the content from the capture hardware, produces it, and sends it to the viewer's computer on-demand.[6]

Modern lecture recording software supports advanced features such as indexing through OCR, instant search, real-time video editing and annotation, along with other advanced features.[7]


Lecture recording is often used in the flipped classroom learning model as a means to provide materials outside of traditional lectures or seminars. Students are able to self-study by playing back and interacting with recorded lectures.[8]

Some educational institutions use lecture recording as a means to replace the traditional classroom with an online classroom. Lecture recording can also be used to create reference materials as a supplementary resource.[9] Some firms may also use lecture recordings as advertising, collaboration, or training materials.[10]

In addition, lecture capture technology may offer compliance with Section 508 for students with disabilities.


Lecture captures are becoming increasingly popular especially with advent and rapid growth of MOOC sites. However, not much research has been done to provide guidelines for recording and presentation of lectures which would be useful for learning.[citation needed]

REC:all (Recording and Augmenting Lectures for Learning) is transnational learning technology project supported by the European Commission under the Life Long Learning Programme, it aims to explore new ways in which lecture capture can become more pedagogically valuable and engaging, and is investigating a variety of learning design, technical and legal issues.
