Internet makes you available lots of PowerPoint templates of varied categories on different topics. Most common categories are business, education, maps, animated, medical etc. Animated ppt templates are just awesome. They catch the interest of the audience and especially in case of medical templates it plays a very important role. By using animated templates in medical PowerPoint presentations you can easily explain your concepts in a wider way to your potential audience. Like if you are ready to make a presentation on heart and its functions than it would be easy to explain if you use animated template in your presentation because the image used in the template will show the pumping of heart and how the blood is flowing etc.
Video _ Video is a great way to take people on a tour with photos, show the development progression of an idea, inspire, teach, announce something new, or otherwise show sequencing and motion. And video is SEO_friendly for websites. Create your slides with pictures, text, and whatever other graphic components you want to use to show your idea concept. Add narration and transitions to your slides, setting transition timing to work with your narration as appropriate. Then use the "Save and Send" option at the "File" menu tab and "Create a Video". You can add music as "narration" prior to this stage of the process, or queue music to the video with a video editor after you create the visual video. I've created many videos using PowerPoint without expensive video production software and equipment!
