Couple of things first. That DVD was produced using the very 1st gen of the HVX 200 ( I did the initial tests with a prerelease camera) – the later versions and certainly the current 200a model has much less noise and more refined gamma curves than the software in the original camera.
Secondly- I agree with Noah about the light – and a properly lit shot will always show less noise in the shadow areas
However by adjusting the Pedestal settings, as part of shooting with Cine Gamma settings allowed the earlier versions of the camera to capture a slightly longer curve in medium to higher contrast lighting environments without showing as much of the compression (often called mosquito) noise in the areas below 15 IRE
Note that I like to shoot “Film Style” and not “Video Style” so I am used to looking a files that have more headroom in the shadow areas and highlights that appear flat or almost muddy to people that have only shot with off the shelf video cameras. So the difference in appearance of my images with the Pedestal set to -6 or so is always adjusted for in post because I set up my camera and post workflow to support that look.
The Extras folder on the DVD should have stills of a DSC test chart showing the effects of the adjusting the PED settings.
