When I take a Keynote (5.3 or 6.0) presentation with images (all pasted PDF files), then export the presentation to a PowerPoint presentation, all of the images become severely degraded. For reference, the original PDf files are on the order of 100KB, so I don't believe they are particularly large…
Is there a way to change this behavior? Having to copy each image over by hand greatly reduces the utility of the export feature. Is there possibly some Terminal command that I can set to make the exports high-quality? I need to export this in PPT so that my advisor can edit the file.

EDIT
Though this question (How to not compress inserted pictures in Powerpoint 2011) seems related, my presentation images are degraded the very first time I open the exported presentation, and viewing the presentation does not improve the resolution.

As there doesn't seem to be any way to make PowerPoint handle vector graphics, the only solution is to export the image to the correctly sized PDF image (essentially treating it the same way one might work with a raster image).
While this is incredibly dissatisfying, it does result in a PPT presentation with unpixelated images…
