Hi Davin,
I have used Wink for a few years now. http://www.debugmode.com/wink/
I think it is better than CAMStudio for a couple of reasons, but the main reason is your output files end up being tiny. I created a 25 min installation video in under 10 megs for one of our software apps.
Here are the steps to create a video.
1. Capture the video screen then, you load it in the WINK editor.
2. Remove un needed frames (eg a lot of mouse movements).
3. Add in nice "callout" boxes to document your actions and put pauses in on the screen.
4. You can also record audio.
5. Create SWF file with play buttons etc right away.
Un fortunately you need to convert it back to an AVI to upload to YOUTUBE.
Also which version of BugNET do you want the installer video for?
