I watched this video (provided by TechSmith tutorials) https://www.techsmith.com/tutorial-camtasia-import-powerpoint-slides.html in order to understand how to take my powerpoint slides and put them into Camtasia. However, when I select "Import Media", my PowerPoint slides do NOT show up in the folder because they do not match any of the file types. I don't understand! In the video it looks like they are using the saved PPT presentation saved in the traditional .pptx format, but it doesn't work for me! What am I doing wrong? How do I have to save the PowerPoint so that I can see all of my slides individually, just like in the video?
