this does seem crazy a dig cam is just a vid cam with shutter especially if you think of live view.
so why not able to set up tv cam looking at test chart that give black lev and pw .7 v
reduce light inc gain to keep correctly exposed picture . now look at the chart with cam or light meter
you know the shutter speed set at 1/50 [ i think it would be 1/50 for interlaced pal ] the tv cam F no now work back to iso
Alternate set shutter speed take pict look up iso in exif data
this would give max iso for the vid cam
