Having looked at both videos - it would seem that the photographer is using a colour digital back on his MF camera. The lab are splitting the file into RGB to play with. The finished (reassembled) file is going to another lab who are using a (very expensive) machine to make internegs. This is a heavy-duty commercial operation.

In this case, the photographer only takes the picture - everything else is done for him.
