Our College of Nursing & Health posts podcast lectures on iTunes U. Perhaps video podcasts might be useful for library tutorials, but I really have doubts about whether the screen resolution using Camtasia or LecShare is good enough even for a regular size computer monitor, let alone an iPod. I am working on a narrated CINAHL tutorial using LecShare, but the slides seem to be much clearer as a straight PowerPoint slide show than they are when they are converted in LecShare. This probably has to do with the compression required to convert it to a video file?
The same issue is a concern for posting tutorials on YouTube. There seems to be a wide range of resolution based on the videos I viewed. I guess it has a lot to do with the software, equipment, and settings used during the recording process. I did find an existing CINAHL tutorial from Salve Regina University. To me, it seems blurry on the wide shots and clear in the close ups. Although I would like it to have better resolution throughout, I guess it is sufficient to get the point across–assuming students will look for it on YouTube. I think students probably use it more for entertainment and their posting their own school projects than for viewing lectures and tutorials posted by others.
Here is the video I mentioned:
