I can speak directly to Camstudio. It will output to flash files, which go nicely into Moodle with the media filter turned on. Just upload the file into Moodle and create a corresponding resource in the course.
The only problem with this approach, is that if you have the filter enabled and include several videos in a resource (let's say a label or a single webpage), then all the videos will start to download when you view the resource. Even though the newer version of camtasia allows you to create a "YouTube type" look, the videos don't wait until they're clicked to start downloading. For example, here is a page of embedded YouTube videos:
http://www.georgetownprofessor.net/podblog/?page_id=106
Including several of these videos on a single page works fine since they don't start downloading until you click the movie. The only problem here is if YouTube is down or running slow, then it will impact the loading of the thumbnails.
However, the link below shows a video produced with Camtasia and uploaded to my website. Notice I only have a single video embedded on that page with links below it to other videos in the series. Had I put all of them on that page, like the example above, it would lock-up most computers since all videos would try to load when the page loads...it doesn't wait until the image is clicked like YouTube.

Of course, these are all on a WordPress blog, but the same concept applies in Moodle. If you are going to upload videos in Moodle and embed them, then they should be placed on "separate" resources (like webpage resources) so they are not all loaded at the same time. For example, either just link to the html pages or embed each movie in it's own webpage resource.
Note: this is based on Camtasia Studio...I haven't used Camstudio, but I see no reason why the basic principles here would be any different.
