The term video podcast is used for podcast feeds that, instead of audio files, deliver video which can be downloaded and viewed on demand. In educational settings, and in a similar presentation to enhanced audio files, video podcasts commonly contain a video recording of the lecturer that is intercut with the lecture slides. Video podcasts can be used to distribute screencast videos, as well (see example below).

Videos produced for podcasts can be downloaded and viewed on iTunes and other desktop media clients. These video files are formatted to be web compatible, so that they can be played on portable media devices (iPods, iPhones, and Android devices) and can be embedded in web pages and wikis. Videos produced for use within podcasts can also be uploaded and viewed on social video sites such as YouTube.

Video recordings are good for capturing:

  • Full speaker and presentation video recordings.
  • Demonstrations of actions on a computer screen (or visualizations that are not limited to images).
  • Complex demonstrations or analytic re-enactments.


Educational benefits for this media:

For instructors:

  • Video can be used to organize an image of the speaker and related presentation materials into re-usable media.
  • Recorded screen image summarizes and highlights terms and text, while elaborating on topics.
  • Recorded video can go into detail for images that are hard to explain (e.g. statistical graphs, data charts and models).
  • Video recording archives of lectures that may be content heavy can help students review material after class.
  • Lecture recording can be used post-lecture for self-assessment.

For students:

  • Video images alongside audio recording can reinforce spoken content.
  • Recorded lecture files can be used as a resource for further reflection on lecture subjects.
  • Access to recorded lecture media encourages active learning in reviewing lecture materials.
  • Connects spoken ideas to visual representations and salient terms.

Masterpieces of Western Art

"Masterpieces of Western Art" is a course offered as part of Columbia College's Core Curriculum at Columbia University. The Visual Media Center at Columbia University has produced numerous videos that students use alongside the class to help them think critically about art. Video demonstrations review classic works such as Amiens Cathedral, Raphael's Fresco of the Disputa of the Vatican's Stanza Della Stegnatura, and more. "Masterpieces of Western Art" began offering a podcast of these videos in 2008.


Lecture Capture
