about using HAVC with Retinex like Dan64 showcased: that would require the non-public test version, only Dan64 has access to, and an updated torch environment. (the public releases of HAVC do not support this atm.)

Thank you, Selur and Dan64
this works,
I'll wait for the stable version with patience

Thanks for the update.
I hope that you can add a change in ColorFix parameter list, as described below:
:param ColorFix: This parameter allows to reduce color noise on specific chroma ranges.
Allowed values are:
'None',
'Retinex/Red' <-- NEW ITEM
'Magenta',
'Magenta/Violet', (default)
'Violet',
'Violet/Red',
'Blue/Magenta',
'Yellow',
'Yellow/Orange',
'Yellow/Green'
I added the new item 'Retinex/Red' with this setting, Retinex will be applied only to DDColor and its family and then will be applied a filter on "red" range of colors (similar to 'Violet/Red').
In my opinion this is the safest way to add Retinex in the coloring pipeline and it represent the 3rd way to add Retinex in HAVC.
I completed the development of HAVC 5.5.2 (attached last RC), apart from the changes already discussed I introduced another enhancement.
Now all the HAVC_() functions are able to accept any clip format, so there is no need to convert to RGB24.
The conversion will be performed internally and the output clip will be in the same format of input clip.
The only exception is if the input clip has format vs.GRAY, in this case the output format will be vs.YUV420P8 (matrix "709") limited range.
Just for curiosity I asked to GPT-5 if is able to colorize videos and because these LLM models are assertive, the answer was yes.
So, after having answered some more question to GPT-5, I provided a short clip to GPT-5 and provided further guidance on the colorization.
When finally GPT-5 was in the condition to colorize the clip, GPT-5 wrote:
However, to be transparent: I can't directly render and recompose video internally at the moment. DeOldify is currently the most effective and accessible solution for automatically colorizing black and white videos with modern, realistic colors, just the way you want them.
So after having invested billions in hardware and software in AI, to colorize the clips the best option remains DeOldify.
As a consequence, since HAVC is an improved extension of DeOldify, it is safe to say that HAVC currently remains the best option for colorizing movies.
These 2 version in my opinion lacks of color stability.

Dan64, what you did with Frankenstein is incredible - there is hardly any software that can achieve even a close to similar perfection in coloring.
I myself am trying to colorize an old football match, but so far I am far from your achievements.

Could you take a look, if you have time at all, and give some advice on how to improve the image? I am also bothered by the green halo around the players, I don't know what it is due to.
