BT.709 to BT.601 conversion with ColorYUV ?

[Brazil2]

Is it possible to do a BT.709 to BT.601 conversion with ColorYUV ?
And if so, how to do it ? Which parameters to use ?

I've read the documentations but it's over me and gave me a headache so any help is welcome.

I know about ColorMatrix but I want to know if it's possible to do it with ColorYUV.

I don't think it can. The documentation says nothing about being able to convert colorimetry.

What's wrong with doing it with ColorMatrix?

Yeah, using ColorYUV to do this is unneceassary and will only approximate the values, I think. If for some reason you don't want to use the ColorMatrix filter (why not?), there's also a BT709ToBT601 filter available here:

Except the entire AviSynth site seems to be down for me at the moment.

Never mind, if you want it, I found it at TR Barry's site:

OK thanks for the info.

I have nothing against ColorMatrix but after trying many tools and GUI's I've finally choosen to use Avidemux because it's quite simple and easy to use for all my family, and also available on both Linux and Windows.
But ColorMatrix is not available as one of the built-in filters, whilst ColorYUV is, and unfortunately I don't have the required knowledge to port ColorMatrix to Avidemux.
