Area-based Spatial Filter For PAL

[alexh110]

Does anyone know of an area-based spatial filter, that will only allow a change in PAL phase quadrant if it finds a luminance boundary?

I need it for a chroma noise reduction experiment.

If there isn't a filter, would a combination of filters do the trick?

This isn't what you want...

mergechroma(last.aWarpSharp(depth=20.0, thresh=0.75, blurlevel=2, cm=1))

...but it will attempt to create sharp chroma boundaries at any luma boundaries it can find.

Cheers,
David.
