No, ConnectVideo is a standalone tool.
You absolutely don't need to use it in combination with ConnectRetarget, ConnectExplore, or any other tool.
ConnectVideo alone is enough to create Super Video Audiences with up to a 365-day attribution window -- including historical data even before you’ve started using ConnectVideo -- and it’s the ultimate cure for creating retargeting campaigns on Facebook™.
