Hi, I'm school-teacher and would like to capture my lessons on video. I have 3 requirements. 1. powerpoint / keynote 2. video that can show myself 3. area where i can write or draw (like a mini blackboard at the bottom of the screen) The closest I have got is to use screenium where I can use keynote and having a video of myself teaching the lesson. However I am not able to add an area where I can do typing or drawing. Can anyone offer some advise or software to me please?
