0-255 colorrange to 16-235 colorrange in RGB colorspace

[EncodeThis]

I was wondering what filter or plugin I should use in AVIsynth in order to get some video footage that I have that is in 0-255 colorrange to 16-235 colorrange in the RGB colorspace? I already know there is a filter in Virtual Dub but just wondering if there is one in AVIsynth.

The coloryuv filter will let you convert between TV scale 16-235 and PC scale 0-255.

Colormatrix is used for BT.601 <-> BT.709 conversions

Thanks. But now where can I go to download these filters?

Levels and ColorYUV are both internal and ColorMatrix is found with a quick search.

I don't think it needs a filter. Just add Levels(0, 1, 255, 16, 235, coring=false) in your avs script.

And for completeness in RGB space you could use :-

RGBAdjust(r=0.859, g=0.859, b=0.859, rb=16, gb=16, bb=16)

This is an internal filter.

If changing between YUV and RGB colour spaces then matrix="PC.601" or "PC.709" avoids any PC<->TV levels conversion.

And Levels() can be used in either YUV or RGB colour spaces.
