Here is the background:
"In YCC 709 (itu.709 is the norm for HD televisions, except some very very old ones that followed SMPTE 240), black is mapped to 16/64 and white to 235/940 in 8/10 bits. Values below 64 (10 bits) are called super black and above 940 super white. The "super" colors are mainly used for color correction as they won't be noticeable on the television."
This is clear as well. BUT, if you work in Davinci Resolve should I set the scope range (waveform/parade) to 64 and 940 if I'm monitoring in Rec.709? Or it is useless because I see what I get (I work on a calibrated Sony 2541 Settings: Color Space ITU709, Color Temp. D65 and a Decklink Extreme 3D).
I'm assuming, that after grading, I just have to set the "video levels" in the delivery page to avoid illegal signals and I'm done.
