You can get a good idea of the angular speed of the object this way, but not the physical speed because you need distance to object or size.

I mean, I wouldn't use the word.

I know they like to use the word instantaneous acceleration.

There's no such thing.

There's just acceleration faster than you can measure is what it would be.

Nobody wants to say that, though, and it doesn't sound as cool.

So it's clearly accelerating at a very high rate, but it's hard to know what that rate is and how unreasonable it is.

That's great.

Now what I was focusing on just now was the ships.

if you know what kind of ships they are, then you know the size of the ship and the wake size, the wake angle,

is going to be related to the speed of the ships in the water.

So if you knew the size of the ships and you can measure the wake angle, you might be able to get the speed of the ships and the distance to the ships.

Now this object is clearly closer than the ships to some degree.

So it might be able to put some bounds on sizes and distances this way.

But there's something funny about these ships.

I'd have to look at other videos of ships, but it looks, I mean, these ships are all oriented in almost the same direction.

They almost look like they were pasted onto the image, which is a little weird.

Have they redacted the ships in some way?

Is that a redaction that they pasted onto the ships so you can't tell what kind of ships they are?

That's what it looks like.
