Illustrated Commentary?

I have been looking for software that would be used for making an illustrated commentrary. Where lines and arrows point to specific objects in the movie clip but dissappear after a few seconds. If anyone knows where I could find any software/freeware that does that, I would be very grateful.

sorry on my now deleated entirely inapropriate post…

Myself I’d use either Flash or Final Cut Pro (Using the title options) - eccept that both are overpriced propiatry software.

try powerbullet!
