Every production requires organization on many levels no mater what the content might be. One of the easiest tools to help with this is actually PowerPoint. By creating a slide sequence clarifying your content, including images and such basically is a type of story boarding.. During this process, you are making many choices about content to be relayed, the depth of content to be covered, visual aids and audio supports such as narration and or music. While this particular planning stage doesn't have restrictions regarding media use, you must bear in mind that copyright permission has to be determined and acquired as needed, if you choose to use the planning images and or music in a posted production. With this in mind, you should consider checking usability requirements for any media, not created by you, even during this planning process. The reality of our cut and paste virtual world is that all media has to be treated respectfully and legally.
