As i often was asked in my workshops “How can i import my own vector graphic images into Prezi?” the answer might be also from interest for this community:
The direct importing of a SVG graphic via “Insert|Image” might sometimes work for SVG files or lead to an error message. Either way - the result is not satisfying as the image got converted to pixel graphic during the import.
If you want to insert a vector graphic file (i tried out SVG and AI) you have to take some prior actions, then it works like a charm (even with a BASIC account).
