With Yopbox, that makes only a few minutes to do a demo video like a pro.
You can script, shoot (screen + face) your video without knowledge. And the edit is automatic. Very easy to use ---> https://www.yopbox.com
I am working with a product called screengif, it lets you capture your screen and convert it into gifs.
These gifs can be faar more easily inserted into newsletters, your websites and their short nature hold your users attention.
Great way to show your product in action imho.
Let me know if you are interested and I will give you the beta access, once we open it.
