file too large to email after optimization in Powerpoint 2013

I have a Powerpoint with embedded videos that's about 33k KB before I click "Optimize Media Capability." Afterwards it jumps to 172k KB, and I can't email it. I tried compressing and zipping, and neither takes it down enough. Is there a way to reverse the optimization? Not that that really fixes my problem - I need to send the PPt to several ppl in an email and have the videos work on their computers. Is there a way to optimize so that the file isn't so large? What all is it tacking on anyway? Alternately, why isn't compressing or zipping working?

Thanks for any feedback!

Well I realized that I had the problem wrong. The 33k KB size was actually an older file from before I added the videos - so it wasn't media optimization that inflated the file, but the videos themselves. Further research has led me to believe that I probably didn't need to click optimize media anyway, as PPt 2013 embeds automatically. The real problem is simply that my file is too large to email and compressing and/or zipping doesn't help. I would love feedback on that!

I clicked "solved" because I didn't know how to delete.
