The first shot can be cropped, yes. I will try to clean up the second shot. I have also thought about creating a new shot, like you say. I even ordered a pair of cheap chinese Solo dice online yesterday, we’ll see if they look good enough when they turn up.
As you say there is a bit of a continuity issue going from the original shot in the movie to the first new shot with the dice so I’m trying to put a different shot or two between them to make the transition work. There are a few more shots of Han in the cockpit in the documentary, so I’m trying a few things with those.
