You should get Camtasia, both are able to be done in Camtasia, only downside, if you want one that doesn't keep crashing, you gotta pay, if you get a free pirated one, more than likely it'll crash every 5 seconds.
I have used leawo video converter for a long time. It has a simple, clean design but it is powerful. The program can convert video and DVD to more than 100 formats and you can edit the videos with this program too. Here is the link: http://www.leawo.com/packages/total-media-converter-suite/ Hope this can help you.
