Option to create animation GIF file from animated slides.
It's 2017- Come on Microsoft we need to add that feature to PowerPoint - Converting slides to animated Gif with transition, this should be part of Microsoft Office 365 or Office Pro 2016. Animated Gifs are the way to go.

We can't create an animated GIF from animated slides but at YOUpresent, we are about to release a PPT2GIFa add-in that is designed to help you make animated GIF images from PowerPoint. This is not the same design need as the request in this question so we vote for Microsoft to add this too. You can get the free add-in here : http://youpresent.co.uk/free-stuff/free-ppt2gif-converter/
