Cloning this effect in Staxrip / Avisynth

[salvo00786]

Hi...

First of all, thanks for all your support for the past questions.

Now I have two questions. It's possible to use a Lumetri cube file in Staxrip / Avisynth. If this is possible, how to use it?

Now the second question that is more complex.

After QTGMC, I use sometimes this effect (BCC Broadcast Safe) in Premiere that is beneficial for some files and not for some other files.

Let me explain. Here there is a screenshot of the normal file without the effect

This is a screenshot with the effect applied

Someone can explain to me what this effect does? It's something like it brings out hidden details. And why on some files, like in this case it bring out all these details and in some other files it does absolutely nothing? It's possible to reply this effect wth Avisynth / Staxrip avoiding the use of Premiere in the process only for this effect?

3D LUT .cube files can be applied with AVSCube (http://avisynth.nl/index.php/AVSCube) in Avisynth.

Or DGCube for avs or vpy . CUDA accelerated

The "hidden details" are because of high red saturation . Whenever you have very high saturation (any color), it can obscure details . On videos that have normal saturation, nothing will happen with that filter, because nothing is obscured . Most broadcast safe filters are "smart", in that they don't globally reduce saturation - they selectively adjust only areas or colors or levels that require it .

Do you know a broadcast smart filter that can auto correct saturation for avisynth?

There have been attempts, but they tend to do it crudely.

There tends to be more logic involved (smarter), more selectivity (less damaging), for some NLE broadcast safe filters and plugins. (Some of them are crude too)



You can try this one, but I think it clips instead of selectively reducing saturation in an affected hue range . If it clips , as the graphic suggests (the hardline) that can produce undesirable results in some circumstances

Ok, thanks for this. Another question:
if I want to use this:

Neo_f3kdb(dynamic_grain=true)

and this:

CAS(0.5)

What is better to use first?

I think that is better to use first CAS that sharpen and after that Neo_f3kdb(dynamic_grain=true), because deband and add grain as the last step, but tell me if my thinking is wrong.

Yes - But it depends on the source and scenario - you run the risk of sharpening grain if you use CAS after . In general I would probably be better to use CAS first. But for some cases it might be better or worse. You have to check on your source - preview it

this was exact my thinking, I don't want to sharpen grain.
