Sequence showing mushroom cloud formation from a U.S. test at the Nevada Test Site. Probably from Operation Tumbler-Snapper, 1952 (rest of the film is from it). Frames 2-3 look a lot like one labeled as Upshot-Knothole Climax (1953), though.

The scale is not precise, but the entire sequence from beginning to end is about 55 seconds, which makes each frame represent a 2.6 second interval.

A good way to display it is like this:
