Message from Richard Campbell on on July 1, 2002

Attached is a link to a downloadable Demoshield CD browser which can be used as a front end for Camtasia videos. I have implemented a "silent install" of the Techsmith codec to facilitate the playing of the videos. If you do have the Techsmith codec already installed, it will not install again on your computer.

Since on my own computer I do have the codec already installed, I can not test whether it it installs correctly. I would appreciate feedback on whether it installs properly on non-Camtasia equipped computers. If the movie does not play properly, it is not installed. On a CD, I could include an autorun.

This is a single-file-executable and is 3.8 megs.

Some Camtasia questions from Rick Johnson accompanied by off-the-wall answers from Bob Jensen

Johnson
Here are the specific questions I have. Below that, I briefly describe some of the things regarding the videos that I am thinking about. Finally, I provide a link to a math prof at Michigan State that has a number of videos (downloadable and streaming) that you may want to check out... Thanks!

1. Has your enthusiasm regarding the use of Camtasia type videos in accounting increased, decreased, or shifted over time? 

Jensen
My enthusiasm has not diminished, but my students did run into problems with the sad state of audio on most of our lab computers. Students have to check out earphones, and the audio does not work properly about half the time.

I am hoping that the lab situation will be fixed up this summer.

Johnson
2. Do you still have a strong preference for the Real Media format over AVI? 


Jensen
Our students cannot install the Camtasia reader or any other software on lab machines on campus. These machines get :rebuilt so often that we cannot rely upon the installed Camtasia reader being there when students need to use the files. The lab machines can always play RealMedia, so that is a real RM plus.

Also RM files take up much less space on the server.

Johnson
3. I noticed that you don't use streaming videos on your site (yet?)... Are you interested in them for the future or do you feel that downloadable/distributable cdrom files are more reasonable for education?
 

Jensen
Yes, I would like that but Trinity is a long way from serving up streaming media. I do not recommend running your own server for any files that students depend upon. Serious servers need constant backup and maintenance, which is something that accounting professors should not be doing. 

Johnson
4. What has the student reaction/perception to your videos been so far?

They don't particularly like them in class. They do like them outside class, especially my videos on MS Access.

Johnson
5. Are there lingering technical problems that hinder the use of production and distribution of the videos?

Jensen
The process is a bit slow and takes some practice. The files also take quite a lot of server capacity. This is not a good alternative if your university is stingy with server space.

Audio can be a pain in the tail, especially since Camtasia will only capture microphone audio and not from pre-recorded audio. For example, suppose you want to capture a video/audio segment that is on a file inside your computer. The only thing you can do is turn your speakers up full blast and hold the microphone if front of the speakers. Even then, I can barely hear anything in my Camtasia recording.  (In a subsequent message, Rick Johnson said he has had luck with a trick wire connecting the Audio Out and Microphone In ports on the back of the computer when capturing computer audio.)

Johnson
6. Have you gravitated toward specific frame rate captures or screen resolution?

Nine frames per second.

Johnson
Here are a couple of the things that I am currently testing regarding the videos:

1. I'm testing the use of screen shot captures from ebook versions of texts using the actual end of chapter problems in the videos. Frequently, my students don't understand what the question/problem is asking so this might allow me to highlight passages or sections and explain. My concept is to video capture a horizontally split Windows screen with the Question displayed on top and an Excel spreadsheet on the bottom in which I can develop the solution. Hopefully, when necessary and appropriate, I can toggle full screen on either section and back again. [Jensen, Robert]

Jensen
That should work OK unless there is audio in your eBook.

Johnson
2. I'm testing the incorporation of the animated characters from Microsoft called Agents to narrate parts of the videos through the use of a program called VoxProxy www.voxproxy.com  . This approach would require some editing with the Camtasia Producer. I'm not sure if it will be worth it. So far, I've noticed a big increase in file size. Maybe in the end, I'll learn that the no-edit approach is the most reasonable?
 

Jensen
RM file size may save you space.

Johnson
Finally, here is the Michigan State University Math Professor's website with Camtasia videos - http://www.math.msu.edu/~winter/106/avifiles/lecture13.avi 

Thanks in advance for your reply (if possible),
