Just as IC8 was released my life turned upside-down and is just now starting to stabilize, so I'm just now starting in with IC8, and I've already run into a crazy issue.  I had been working on a project in IC7, a 43 second video whose iProject file is under 500 MB.  I loaded it into IC8, made no changes at all, and saved it again, the exact same project now in IC8 format.  This iProject file is over 5 GB!  Why is the IC8 project file about 12 times larger than the same project in IC7?  This will make backups a nightmare.  Does this happen to everybody, or is it perhaps just something unusual about my project?
