I had not seen that before, very tempting.

If there was any sound on the video, I couldn' t hear it, so does 
anyone know what the 'pen' was?

It looks like a highlighter, but clearly thats not the case. I assume 
it wasn't solder paste, as this regular solder was used.

I assume therefore that it was flux, but then the iron was used to 
'glue' the chip into place.
I guess that must have relied upon the tinning on the PCB,

Anyone any experience of this?

What sort of thickness of solder is required. It looked about the same 
width as the pitch of the pins (or at least thicker than the width of a 
pin).

Yep, it was flux.  The solder is 0.015" diameter.  More on his webpage
