Yes, only the few seconds with the boats. No need to see the entire thing.Are you talkibg about this one at 15:15 on the Civil War monitor?
I believe some of the footage they would not need to alter. Who can say what this flag really is? It resembles the US flag but as we know quite a few things could be displayed on it.
You wont see it on your phone, you need a monitor. And increase the contrast if you can.
Something is not right, but no idea why.
