How about forgetting that video for a moment and trying to consider the following picture: https://static.projects.iq.harvard.edu/files/styles/os_files_xxlarge/public/eht/files/unnamed-2.png https://static.projects.iq.harvard.edu/files/styles/os_files... Taken from here: https://eventhorizontelescope.org/science https://eventhorizontelescope.org/science (the official site of the project). On the left is how it would look like if we weren't so far -- we are 55 million light years far from that. You know the distance from us to our Sun, which you see on the sky but can cover with your own thumb? That object is 3,500,000,000,000 times farther than the Sun is far from us. On the right is what we can reconstruct from the signals measured because we are so far and we have "only" the telescope the size of the Earth. More details would be visible (the picture would look more like the one on the left) either if we had even much bigger telescope than the Earth, or if the black hole of the same size were much closer to us, which it is not.
