I have used some of these resources for Camtasia projects in the past and wanted to share the info for anyone that may not know this exists. I think that at least some of their products may be able to be used in other video editing applications as well. If nothing else you could open these in Camtasia and then export the desired results to be used in another application. Of course you would need to have Camtasia to do that but might be worthwhile. Some of the resources available here are pretty cool...
