Everyone is familiar with PPT which is a commonly used software that our teacher use most to make courseware’s in order to make an exquisite PPT, and convert The PPT to video disc for me very difficult I also spend my time to do that if i have some presentations because we need to make it clearly good and working because Some students post PPT video sometimes they can’t open it in the PowerPoint or the word that they doing because it’s not working they need to go back to documents to open the video. That’s why i think video post in PPT also very important and difficult for some students.
