I grabbed that from one of the videos I though had the highest res. Dragging the timeline left and right gave maybe one or two other frames you might be able to use. Initially I was thinking Mason symbol, but it looks more like an X or a cross with receding points. Red backdrop maybe?
Can no one here clean up and blow up the image? I am versed in symbolism, due to my graduate degree in art history. Autists assemble!
