description: Convert the image color to whatever was requested by the consumer. This filter is designed for use as a normalizer for the loader producer. If the "force_trc" property is set on this filter, the filter will force the output trc to be "force_trc"; Otherwise, if a property "consumer.mlt_color_trc" exists on the frame, then it normalizes the image to the trc requested by the consumer.
