Joe, watched your vent cleaning video. Appears you only blew out a sampling of the lint.

Harbor Freight has a stiff round brush mounted to a flexible shaft that can be used to insert into the vent pipe and work loose the lint and debris. After that, then fire up the blower while your wife stands real close to the outside exit for a close up video. You'll be doing your own laundry and meals for weeks to come.
