Over the years I've come across a couple of people who've professed to have

Amadeus or Farinelli on TV and they've both not reported any problems
despite AFAIAA 24 frame per sec film is shown at 25 frame per sec on UK TV
telecine so a 4 per cent frequency shift, whatever that is in semitones.

A lot of people believe perfect pitch is something other than what it
really is. I have very weak perfect pitch, in that during periods when I'm
doing a lot with musical instruments I can remember a note like A, and
mentally walk up or down the scale from there to the note whose pitch
I'm trying to name.

I am easily aggravated by a single instrument that's out of tune, even
slightly, in an entire orchestra. Of course, accurate instrument tuning
is the most obvious thing differentiating professional orchestras from
grade-school bands.
