I would offer some advice. Your objective is not to present the entire contents of the paper. Your paper is, presumably, available. Your objective is to present an overview so that someone gets the idea of what's in it.
Picture this. In the future person A, who was not at the conference, mentions a problem to person B, who was. You want person B to say "Ah - I say a presentation about exactly this. Here's what to look for!"
You want enough content to give an accurate impression of the content and why it's interesting. Then you want something memorable for people to look for later.
Note: I'm not in your field, but I do give presentations professionally. You need to entertain and inform. But your objective is to be memorable for the right reasons.
Email me your topic and I might - repeat might - email some thoughts.
