I have an intel Core i5-7200U @ 2.5ghz, 8GB Ram, Windows 10 Home.

I have tries several different source materials, I have even opened a previous project and went straight to export and it still hangs.  I have let it sit for over an hour.  I have many different export settings from file types to qualities with the same results.   I am not sure what timeline settings you are referring to.

thanks
