EXCLUSIVEWhen Dwyane Wade popped the question to Gabrielle Union, he made sure he had the camera crew ready -- and used the high quality footage to put together a "save the date" video for their wedding guests.
TMZ Sports obtained the mini-movie the couple sent out to everyone invited to the shindig ... showing the moment Wade got down on one knee and popped the question.
