Abstract
A video processing device can determine whether an input pixel includes a keyed video parameter prior to filtering the input pixel. A non-keyed substitute pixel can be generated for the input pixel that includes the keyed video parameter. The non-keyed substitute pixel can be filtered if the input pixel included the keyed video parameter, otherwise the input pixel can be filtered.
