For some reason my title/action safe overlays are not showing up over my video. It's strange though, because if the time code overlays are on as well, you can see the outline of the title/action safe lines in the time code box. It just doesn't show up over the video. Hopefully I'm explaining this sufficiently.
You have to also select show overlays in addition to which one you want. I can't remember the short cut off the top of my head but it's under the same drop down menu
The title safe overlays are turned on in the frame on the left and turned off in the frame on the right. As you can see, the aqua colored lines are visible in the 1st frame, but only within the overlays for In, Out, Video and Audio. I've never seen this before as they usually cover the entire frame.
