It seems the writer of that has no personal experience such as
single-stepping through movies or recorded TV to re-examine something
noticed in rapidly changing scenes. The VLC Player is a good tool for this.
A single frame at 1/24th (film) or 1/30th (US TV) of a second may be visible
and remembered. Can you see fast-moving insects?

I can make out single short words, longer ones aren't all in focus.
When I was a film maker's technical assistant we experimented with a
variable frame rate projector to explore visual persistence and "flicker
fusion" which are important for the frame-by-frame animation and stop-action
live actor filming he was doing. For me individual high contrast frames
could be distinguished at up to about 28 per second. I could see M60 tracer
bullets passing overhead, and I can still resolve the individual wheel
spokes of cars passing at 40MPH with my peripheral (side) but not my foveal
(central sharper) vision, which is indeed slower.
In 6th grade the Evelyn Wood people came around to promote their
speed-reading course and give a test to show us how badly we needed them. I
found I was already reading at 600 words a minute, 10 per second, and I wear
glasses for poor eyesight.
