Softwares to screen capture

[Extrudeface]

But that one is commercial... IE, at least Active Presenter has a wonderful fully functional totally free version... (I use it a lot as a capturing tool (very good performance), have not yet used its presentation making capabilities... Well, did once for a small thing)

IMO, if one is ready to put 30 bucks in a tool, I'd rather go for Sony's cheapest Vegas video editor. You put like 40 more, but you have a full blown editor that can also export to mp4. And for the mere act of exporting/converting, imo nothing comes easier than handbrake. Just like with any tool, gotta be aware from were you download it, be sure is the author's site, as I have encountered one fake site containing a virus. But then that was definitely non related with the actual author.

Way more complex to use than the easy and great handbrake (for those willing to experiment), and I deeply love them: Mediacoder and ffmpeg (this one command line, console only) , they have binaries for the 3 platforms. Waay more complex to use than most stuff out there on the matter, but extremely flexible. I don't feel uncomfortable, as I remember back in the days of MSDOS, plus quite some years with Linux (average user in both console and GUI). The other free command-line tool I like a lot is imagemagik, mostly for image sequences processing. (often combining it with VirtualDub of the like)
