Build 54 is not generating the correct burn in. There are artifacts that render the burn in unreadable and the burn in is not appearing in the correct location on the frame.
Also I noticed that the opacity option that was available in RedRushes for both the text and the background is no longer available in RCX. It would be nice to have this back.
An image showing this is attached. You can see the burn in settings in the screenshot. The ouput format is ProRes 422 at 1280*720.
