Thanks for the reply.
Using “full range”, the video scopes:histogram (luminance/r/g/b) shows the values 0-255
Using “video levels”, the video scopes:histogram (luminance/r/g/b) shows the values 0-238 ( mostly – Mostly the values near 255 shifted to lower values. values near 0 did not nearly shift as much. )
What I also learned is that the “digital” “color bars” do not appear to be so perfect when displayed on the various vegas video scopes. For video scopes:vectorscopes there are 2 dots in each of the B/G/Y/R boxes. Mg/Cy boxes have only one dot. The Histogram for the R/G/B values are all different.
