Do you have a source for that?
No one would have a reason to 8,000 frames a second of another standard Trump rally, unless the liberal knew this was going to happen.
That claim of 1/8000th of a second shutter speed (not frame rate - that was claimed to be 30 frames per second) is reproduced here:

... which is an image of text, sourced to gab.com:
There’s no author noted on the gab image, but the text says: “the New York Times photographer, Doug Mills, is quoted as shooting at 30fps 1/8000.”
