SWF file size on Screencast.com
Jun 17 2008, 12:51 PM EDTI have noticed that my Camtasia productions have been getting larger, the last one is 84MB for 3.30 min. This can be slow for a user to run depending on their broadband capacity. Using the video editing tools in Camtasia such as zooms and callouts adds to the recorded size of the .avi.
There are two solutions:
1 - make the tutorials plain vanilla so that a swf will be small. This seems to defeat the purpose of developing rich content.
2. - Use swf for downloading and alternate versions for delivery. There is another thread that discusses how to use embed code and have screencast.com serve the tutorial, that still requires good bandwidth to deliver a 84MB swf file.
The alternate is for a site to download all 3 files from DSpace, then edit the Camtasia file themselves. Once you have the 3 files in a folder, you can produce the tutorial to a .flv which will be much smaller. You will need to serve the files from a server that handles swfs. The much smaller flv is contained in two wrappers, a HTML file and a swf wrapper that provides captioning, live links, quizzes, anything interactive that you want to add.
Remember that the Creative Commons license lets you modify the source files, i.e. the camrec and camproj.
