== Abstract ==
This is a script to fix color bleeding.

=== Requires Filters ===
* [[ChromaShift]]

== Description ==
The colors that bleed most are the ones that lie in the extremes of the chroma scale (the V channel): saturated blue and red. This Avisynth script, which isolates those extremes, makes a mask out of them and uses the mask to shift the chroma (and lower the saturation) only in those areas where the bleeding is more severe.

== Examples ==
<pre>
Avisource("blah.avi")
FixChromaBleeding()
</pre>

== Links ==
Download [[Media:FixChromaBleeding.avs | FixChromaBleeding.avs]] current known version.
