Blu Ray Color Space
I am having a hard time understanding what the color relationship is in a HD video and a Blu-ray disc. Working with SD footage and now learning about HD I always assumed HD was useing a NTSC single and I would color correct using FCP NTSC scopes. I would then burn my HD footage on a blu-ray disc.
the more I dig the more confused I get and it seems that HD footage is not NTSC dependent if I go from Blu-ray to HD monintor?
Is a blu-ray disc using a NTSC single and there by its color space? If HD and Blu-ray has a better color depth or range then SD video then I would assume that I would not color correct it using a NTSC NTSC scopes and parameters.
It seems applying a NTSC color space to a HD blu-ray single would be dumbing it down.
Sorry for how dumb this question is!

SD and HD use different color spaces.
SD = Rec. 601

HD = Rec. 709

thanks Alan,
this helps out a lot. but I still do not understand why if HD has a better color range do we color correct with NTSC tools like the vector scope or Waveform monitor that are NTSC.
I am an old Photoshop guy and I can’t help but think it is like color correcting my ProPhoto RGB 32 bit color photograph with Proof Colors on to Generic RGB.

Who say these are NTSC tools?
Then the people in PAL land we can not Color Correct?What you need to color correct is a good monitor where you can change the color space depending of the stuff you are playing.
