My question is why did the horizontal part of the 'A' not fill in until after the A was finished?

Yeah, it's faked. You hear the top note in the last chord drop a bit from the next to last chord - but in the MIDI, the top note stays the same.

No, I'm pretty sure that the top note is the same in both chords. Also, as for the letter 'A', it's just that the MIDI doesn't show the note until it's released.. just look at his left hand holding down the note. Not fake

This guy doesn't know who they're replying to.

In all honesty though, it could just be desync between the video and audio, but I'm not going to say for certain since I only work with the video side, not really audio yet.

I see some A/V desync (the audio is obviously late), and I find it extremely plausible that the software does not display notes until after they *end* (note-off). I do not hear the top note moving. I do not see nor hear any evidence of this being fake so far.

Even professional musicians mishear things sometimes, and I'm pretty sure whatever @raphmusic thought they heard as the top note was the second or third highest note . The chords are changing but there's a low and high C all throughout the piece to make it line up.
