When you have invested in a great animated promotion video to put on your website, why not use it in your presentation? A good video can tell a relatively complex story in under 2 minutes. Most of these videos contain high quality art work that is great for use in a presentation.
Embed the video in your presentation (I prefer putting in the actual file rather than linking to an YouTube video) and create visual connections later on in the deck using screen shots of the video (either page-filling or small thumbnails).
Do not feel embarrassed that that video just cut your bullet point product explanation from 15 minutes to just 2, your audience will appreciate it.
