Reverse engineering: which video editing software was used on this video? With my staff we have to create a video similar to 


                
            

We have to start from scratch, buying the software and involving some experienced people.

Which kind of software you think would allow us to make a video like the one of CERN's guys?

In particular a feature I think we need is the possibility of having multiple videos on the screen.

Example: a box with someone talking on the uppre left corner, while some images go on in the main screen.

--UPDATE 1 --

The OS I'm using is Mac OS. If needed I can surely switch to linux, and also to windows 7 (but I would avoid this last option).

Our level in video editing is not really high, hovever I'm a so-called ICT person so I don't usually get lost with new software. But of course a  software with a steep learning curve do not fit well to our needs, because I would take one month just to learn it.

We were looking at Pinnacle studio or iMovie.
Pinnacle has the video-wall feature which is great, iMovide allows for box where people is talking while images go on on the main background screen.
With a 99% chance After Effects was used here.
As long as you plan on doing a commercial video I would avoid home video production programs like iMovie at all costs. Specially because iMovie is made for cutting video and not making animations. That's like making a commercial in Windows Movie Maker.

There are many many talented freelancing After Effects animation artists out there who will make you this kind of animation with ease if you don't want to learn the software yourself.
