the patterns are not actual moving video, but instead are still frames, so you have to make the color changes in TT, then change chapters, and then go back to the chapter you are measuring in order for the changes to take effect.
I am well aware of the issue with still frames and VMR9.
Even though I can clearly see the crushing on the screen, if I crank up the white level, the value shown by the MWSnap color picker is still 235,235,235.
So be aware: The values obtained from the color picker are NOT always the same as what is being sent to the display.
Here are my values for the DVE Title 12 Ch 15-20
Your DVE values ....... my DVE values
75% red window measures 238,0,0 ..... 183,15,16
75% green window measures 0,213,0 ..... 14,181,13
75% blue window measures 6,7,253 ...... 15,16,184
75% cyan window measures 0,205,204 ..... 13,181,181
75% magenta window measures 228,0,229 ..... 182,15,184
75% yellow window measures 191,190,0 ..... 182,181,13
These were taken direct from the screen, using MWSnap 18.104.22.168. Card is an NVidia 5950 Ultra running the 71.72 drivers.
VMR9, renderless full screen or window are the same, ffdshow using Lanczos2 resize and DScaler sharpen, YUV mixing enabled.
