Hi Group,
I am concerned with creating graphics on PC's and Mac's and then moving
it into video production applications.
When I create a graphic in the NTSC color space in Photoshop it allows
me to create colors where RGB values go from 0 to 255. If I then run
the "NTSC Colors" filter, the saturated colors, Red, Green, Blue, Cyan,
Magenta, and Yellow are limited to values less than 255. Some are cut
back as far as 170. Note that the color white is still 255, 255, 255.
Is this limiting due to NTSC composite encoding?
If all of the video production were kept as component video (Y Cr Cb)
could I use the full 0 to 255 that can be reached in the NTSC 1953 profile?
I am trying to understand where the bottle neck is in the video
production process. Is it the NTSC 1953 profiles or is it further
restricted by the NTSC composite encoding?
Can anyone point me to a book on this subject?
Bruce are you going to write a book on "Real World CMS for Video"?
