I've the same problem. But I noticed that using pdf in Prezi really slows the whole thing down. So the best thing I found up till now is to have the pdf in full screen on my molecule, take a png screenshot with PrtScr and insert it into Prezi. Although the smoothing of bitmap images in Prezi is quite good, it can sometimes end up in something ugly. So I'll try to avoid that too.

Still searching for a way to improve it.

Sorry I didn't help you much. I'll come as soon as I find something new and useful.
