Why convert powerpoint to movie files? This is a question that many people ask but the answer is very complicated right about now. You should have to be ready for whatever comes your way and that can be in the form of making movies out of your favorite powerpoint presentations. A lot of corporate employees do this because they want to keep around their favorite moments in the boardroom to view later. Others do this specifically for reasons of documentation. Whatever you end up doing, it is up to you to convert the powerpoints correctly to make sure that they are going to be around for you to see for a while.
