Rotate the hue knob until the background keys through the desired color. Gain The gain adjustment determines how the colors around the select hue are keyed. Adjust the gain knob until the edges of the keyed region appear the way you want them. Ys - Luminance Suppression The luminance suppression adjustment sets the black level of the region where the chromakey level has been removed. Adjust the luminance suppression knob until the black level of the chroma removed region is correct. Lift Key lift should normally be set to zero for a well set up chromakey scene. Key lift allows very low saturation values of the keyed color to be excluded from key. Colored light spilling onto a neutral colored object in the foreground will sometimes cause small areas to key to the background source. Key lift allows you to fill these small holes in the key signal. Narrow The acceptance angle of colors around the selected hue should generally be as broad as possible to achieve natural looking chromakeys. Sometimes, if some colors in the Fill source are too close to the chromakey color, it may be hard to exclude them from the key. Selecting the Narrow button uses a smaller acceptance angle around the chromakey color. Selecting Narrow temporarily, may help you center the Hue adjustment. Matte Preview When a chromakey is on the preview monitor, selecting Matte Preview will display the key signal generated by the chromakey. Viewing the matte sometimes helps solve lighting or adjustment problems. 40 Nova 1416 manual · Check updates at www. echolab. com/1416 Setup with a Vectorscope It is sometimes instructive to set up a chromakey using color bars as the background source, and watching the result on a vector scope as you perform the following procedure. 1 2 Turn off Narrow and set Lift to 0.
