Grab your tone _ After you have an outline and a good idea for what you want to do, it's time to figure out your tone and concept. This step helps you figure out your color scheme, your typography, your images and in some cases, your flow. Mash it all together _ It's time to put it all together as you now have everything you need. Your plan or outline helps you figure out exactly what you will present, your template gives you the organization you need to flow through the presentation beautifully, and your tone gives you the guidance for design you need including everything from typography to color scheme to images.
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!
