Configuring your video settings
q Apply Chroma Filtering to Graphics
Select this option to reduce
the chroma bandwidth of RGB graphics, if needed. For most video
editing programs, it’s best that you not select this option. If your
rendered images appear to be blurred, try clearing this option.
q Apply Edge Filtering to Key
Select this option to help eliminate
distorted or “ringing” edges in your keyed images. This problem
typically occurs in hard-keyed images where you have abrupt changes
between opaque and completely transparent areas. Because edge
filtering reduces the sharpness of your images, you should apply it
only when needed. For most video editing programs, it’s best that you
not select this option.
q Allow Super Black/Super White Output Select this option to allow
the lowest luminance level of your output signal to fall below the
standard black level, and the highest luminance level to exceed the
standard white level. When producing your final video production for
broadcast, you should clear this option to ensure that you output a
standard (legal) video signal.
