DVO Cross Colour
Cross Colour (also known as Chroma Crawling) is a defect that results from
crosstalk between the chrominance and luminance components of a
composite video signal (PAL or NTSC). Once a video signal has been in the
composite domain, this defect is not easily removed.
Parameters
Enable
When enabled, DVO Cross Colour will process the input as per the settings
described below.
Aggressiveness
Allows the tuning of the degree of removal.
If we increase these parameters too much we increase the
possibility of introducing artifacts.
Spatial
When the Temporal setting is decreased, The Spatial control may be
increased instead to remove cross-colour at the expense of slight spatial
chroma bleeding.
Temporal
Increase for maximum cross-colour removal. Reduce if temporal chroma
bleeding becomes too intrusive.
