.story File Size Question

Was this ever resolved?  I have ASL 3, and am experiencing the same issue after replacing 2 videos, 720p mp4's a total of about 7 minutes of length to them. My project ballooned from about 750MB to something like 1.2GB.  Save As led to a file that was identical in size. Saving is now even slower than it was.  I'm not in a position to share my .story file however so I'd be interested in what i'm looking for and how to engage support.  This story may have some roots in storyline 2 if it makes any difference. 

Edit:  interesting.  Initial Save As of the file kept it up at 1.2GB.  When I quit storyline though, I checked the size on the new file again, and it was back down to the 750MB range. So it appears the Save As ultimately did work when combined with closing the new file.
