I'm trying to find a software for PC, Mac or Linux, which simultaneously plays a video on the left and a given Powerpoint/slides/group of pictures on the right. My goal is to create a video which shows complementary icons, texts, and slides about what the person at the left is talking about.
I've been told to learn using VLC to do that, or even start learning more complex video edit program because it's no easy task. What I'm trying to find is a software than can easily create such a presentation and has a simple interface for beginners like PowToon and Animoto.
Does such a tool/software exists?
Edit: A program like Mozilla Popcorn Maker allowing me to download my videos is EXACTLY what I am looking for.
Edit2: Presentz is, too, EXACTLY what I want. To show slides in one side and video in another.
