About Lecture Capture

Lecture recording - also commonly known as lecture capture - is the recording and post-processing of a lecture or presentation for later viewing, usually over the web. The recordings can be viewed in full or used by students to selectively review and reinforce concepts without requiring additional class or office hour time. Although less common, some capture technologies also allow viewers to connect live and watch an event in-progress.

Common uses for Lecture Capture include:

  • Making lecture content available to students as a study aid, to accommodate varied learning styles, or to support students who miss class due to illness.
  • Recording of supplemental materials or office hour sessions to assist students who need additional help on specific topics.
  • Expanding the audience of a class or event to web-based viewers as part of an open learning effort or to promote a College program or activity.
  • Pre-recording whole lectures from off-campus in cases where the instructor must miss class.

Forms of Lecture Capture

There are a variety of tools and approaches available for recording and publishing lectures. Selecting which tool to use for a particular setting will depend on the lecture content, the presentation format, the location, the intended audience, and the desired level of "production quality" of the final product. Tools range from easy to use automated systems that are well-suited to recording every lecture in a course, to more manual and time-intensive processes that yield a higher TV-quality final product. The most typical approaches to recording lectures in the College of Engineering are:

Recording Method  Best Used For Limitations
CoE Lecture Capture System

 

  • The most automated and easy to use option - a good fit for most classroom recordings.
  • Best for lectures where the content shown on the projector is the most important visual element of the presentation.
  • Recordings can be viewed on the web or as podcast downloads.

 

  • Only available in certain classrooms and recording studios on campus.  Show availability...
  • Editing of recordings is limited to trimming the start and end.
  • Camera angle and zoom is often fixed to an instructor-set position, although a GSI or other assistant can manually operate the camera via a web interface.

Desktop Screen Recording with Camtasia or ScreenFlow

 

  • Best for lectures where the content shown from the instructor's computer is the only important visual element of the presentation.
  • Can record anywhere with access to a laptop or desktop computer, including the instructor's home or office.
  • Provides tools for more extensive editing and post-processing of recordings. 

 

 

  • Instructor must purchase, install, and learn to use screen recorder software on their computer.
  • Editing and other post-production can be time-consuming.
  • Instructor must upload recordings manually to a distribution service, such as CTools, iTunes U, or YouTube.

 

Traditional Video Shoot using Michigan Productions

    

  • The most full-service method of creating a high production value recording or live broadcast.
  • Best for lectures without projected content, or where the video of the instructor is the most important element.
  • Equipment can be brought into almost any location.
  • Best option for recordings destined primarily for TV or DVD distribution, or where live broadcast is desired.
  • Well suited for cases where high production value is required, and significant editing and post-production of the content is planned. 

 

  • Production support staff charges hourly rates for recording, editing, and preparing the recording for distribution.
  • If an ITS method of distribution is not opted for, the instructor must upload recordings manually to a distribution service, such as CTools, iTunes U, or YouTube.
  • End product does not have some of the benefits of the above options, such as slide thumbnails for navigation (CoE Lecture Capture System) or high-resolution screen capture (Desktop Screen Recording).

 

Viewing the Recordings

Recordings made on the CoE Lecture Capture System can be viewed on a range of popular hardware and software platforms, including from within standard web browsers, on iPods and iPhones, and through iTunes U. The instructor can decide which of these formats are made available to the students.

Note that there is currently no authentication required to view a recording. Recordings are grouped into "sites" and assigned a unique URL that must be known to view the recordings. This URL is then most commonly distributed to the students though a CTools site using the web resource tool. This CTools site is typically protected with authentication and authorization.

Recordings made with other tools, such as Camtasia, ScreenFlow, or through a traditional video shoot, are typically served to the viewers directly from CTools or through an alternative distribution method. The CoE Lecture Capture System is not designed to serve content not created within the capture system itself.
