With all the flashbacks and in-universe video and all the time-travel in Avengers: Endgame, it's not difficult to think of points in time that have been depicted multiple times, such as:
Most of the times the heroes traveled to retrieve a Stone from the past
The instant of the Unsnappening, which simultaneously occurs while the main heroes are in Upstate New York and in the high school gym in Spider-Man: Far From Home
But, is there any point in time, which we see three, four, maybe even five or more times?
For the purpose of this question:
The instant must be known to be the same instant (not just likely to be the same time).
The instant can be still or video, part of the film or seen in-universe (diegetic or non-diegetic). However, supporting materials (posters) and parts outside the film (e.g. the Marvel splash screen or parts of the credits) are out. Post/mid-credits scenes are okay, of course.
Different timelines are okay, if we know it's the same instant.
