Hi I am trying to create a darker shape (rectangular) behind the title to have more separation between title and video, both of which are currently bright. I have tried everything but cant find an answer to that. The idea is to have a color or 'faded' space behind the title over the video.
One way to do this is to add a black or other color media generator event to a track just under the title track and frame it via track motion (unchcking the maintain aspect ratio option) to where you want it under the title, and add some blur to suit.
