Ask HN: Tools to make some online lectures tutorials

I plan to build a portal where I we can give away any kind of material to help college students learn basics of embedded systems and robotics.

We are funded by government and have significant amount of funds, we have access to some of the best faculty members.

We are planning to do following

1. Let the faculty give lectures in front of a class and we record it.

2. Let the faculty use screen-casting along with PPT and Tablet.

Can you guys suggest the kind of software we can look at for building course content?

We came across a large number of screen-casting software such as Jing and MS expressions studio. We also liked Microsoft LCD. But none of these tools seem to be very refined.
