Faculty in the Physics and Optical Science department have created hundreds of instructional screencasts that are used in introductory physics courses and in courses on physics for science and engineering.
Initially these videos were shared with students in QuickTime format as downloads from static html websites. These videos have since been moved to Vimeo and YouTube and linked to from WordPress sites:
YouTube is definitively a better service for distributing such videos, particularly its auto-captioning service which will automatically create captions based on Google speech-to-text technology. The automatically generated captions make lots of mistakes, but Google provides an interface for correcting these errors.
We worked with the UNC Charlotte Office of Disability Services to have all the videos professional transcribed and then used YouTube’s captioning service to create captions from our transcription text. This service also allows you to export a captions file. We used this service to import captions to video on Vimeo.
