Just wondering how to use the Measuring Instruments in VPX6 for Broadcast
range of 16 - 235?
I understand that Rec 709 is 0-255 for Web, and perhaps for DVD, Blu-ray,
etc. But I've read that Rec 709 must be set to 16-255 for Broadcast. Some
editors even consider it safest to set Rec 709 to 16-255 for DVDs, Blu-ray,
Web, etc.
In the Measuring Instruments the range seems to go (basically) from 0 at the
bottom to 255 at the top. Auto Correction for Exposure and Colour moves the
Waveform Monitor content, for example, down to 0 and up to 255.
But where is the range for 16-235? I see in the Help Dialogue about the
Waveform Monitor, it says...
'The dotted lines on the upper and lower borders of the waveform monitor
correspond to the values for digital 0 (black) and digital 255 (white).
The lines 0 and 100 on the left border correspond to the limit values for
analog transfer of video signals.'
Does the last sentence (The lines 0 and 100 on the left border, etc.) refer
to Rec 709 16-235? If yes, I find it's easy to bring the white down to the
100 line, but very difficult to bring the black up to the 0.
Anybody any advice on the above?
