I tried setting the HVX at "0" but found it to look muddy. By instead setting the "Master Pedistal" to -6 and leaving the camera at 7, (NTSC Standard), I get better results.
Maybe others have better suggestions though?
Check your scope on DVRack and see if you're getting bumped up or not.
The IRE setup in DV Rack does NOT affect how the video gets recorded -- the IRE setup is determined entirely by the camera, DV Rack just records what the camera send out the DV port. The IRE Setup option in DV Rack merely affects the display of the Waveform Monitor and the Spectra 60 Quality Monitor.
You can change the IRE setup in the Field Monitor menu.
