Reinterpolation411-style script insertion

[Selur]

Will look at it after work.

A fast and simple filter to correct the improper 4:1:1 to 4:2:2 conversion that seems to occur with some NTSC DV/4:1:1 codecs. It assumes the odd chroma pixels are duplicates and discards them, replacing them with the average of the two horizontally adjacent even chroma pixels.

Have you checked that this is the case for your content?

Hybrid doesn't have a preloaded reinterpolate411 filter,

That it is correct, it would use normal conversions for 4:1:1 to xy subsmapling.
