Yeah I'm sorry, but just having an alpha channel enables something to easily have the imagery updated behind it. The actual quality of the graphics on top doesn't need to be paired back like this. Unless all the graphic elements are being live rendered for some reason, you could, for example, do exactly the same thing with the old World Today / Regional News style of graphics, and just have the same footage playing back in the background.

Even if you have the text live generated to enable changes to the endboard, you could still have a much more sophisticated video sandwidged between it and the footage in the background.

And several regions did exactly this with the 2008 Lambie Nairn titles for major stories and special editions. Points West with the Weston Super Mare Pier fire is one example that springs to mind.
