Any good Demo Recording tool?

Question

Looking for a tool that allows to record a user session to be used to create a video demo. Functionalities needed: - zoom-in / zoom-out
- field highlights
- spotlights
- narrative voice recording
- video editing (cut, insert titles or slides, ...)
- ...

Open source alternatives are preferred, although commercial ones are ok (I'd love to do Apple-style videos)

Answer 1

Take a look at ScreenFlow. It's not free, but it has great functionality and publishing options.
