Vignetting Effect

You can add custom vignetting effects to videos in CyberLink ColorDirector.

Shade: use this slider to adjust the shade of the vignetting effect. Dragging the slider to the left darkens the corners of the video image towards black, while dragging it right lightens them towards white.
Size: use this slider to adjust the size of the vignetting effect. Dragging the slider to the left increases the size of the vignette effect, closing in a circle on the center of the video image.
Roundness: use this slider to adjust the overall shape of the vignetting effect.
Feather: use this slider to adjust the edge sharpness of the vignetting effect. Dragging the slider to the left makes the edge blunt, while to right uses more of a gradient.
