Istanbul ferry traffic - GIF

[Toolmaker51]

I do wonder what the real time time frame is for those 50 seconds.

PJs (of this site) was very good at this type of thing. Estimating object size by comparative measurement, timing and elapsed time etc. Imagining his process might run 2 of such things as;
If the distance of a roadway and traffic speed was known, or a sidewalk and duration a person in GIF walked that distance; it could be approximated... I settled for watching prop wash of larger ferries dissipate; sort of. Easiest might be using a known ferry schedule, for an individual vessel to complete a round trip. Another might trace one shadow of sunlight.
I'm guessing it's not less 25-30 minutes of real time.

My frame of mind went elsewhere.

and "Even Old New York was once New Amsterdam"
Why they changed it, I can't say
(People just liked it better that way)

Lol.
