In a Cineform project with CS4.1 & ProspectHD 4.10, I could see the superwhites in my CFHD avis in the YC Waveform display.

I've upgraded to CS4.2 & ProspectHD 4.30, and the YC Waveform now truncates at 100IRE. I have 'maximum bit depth' checked in playback settings - is there another setting I've missed, somewhere?

Anyone seeing anything above 100IRE with these versions?

I'm seeing the same thing, we will have to test whether Premiere is asking for the correct pixel format for displaying the waveform.

I have Premiere 4.2 I have some AVI's from NeoHD 4.0x (not the latest build)
I can see super whites.
