Chris, SMPTE bars were created to set a standard for color in the NTSC range for RGBCYM. You can create your own bars but then they wouldn't conform to that standard. As you summise they are for calibration. As video can have Hue Saturation and Luminance adjusted, color bars provide a reference. The bars you downloaded are fairly accurate and your work should be adjusted so that the bars are a color reference not the other way around. John
