Deoldify Vapoursynth filter

[Dan64]

In the new RC4, the following plugins: Retinex.dll, MiscFilters.dll, ReduceFlicker.dll
Will be automatically loaded by HAVC as needed.
It is not necessary that you add the loading of these plugins in the script.

Okay,.. sounds like a bad idea to me, but no problem.
I assume that you will only implement the autoloading for Windows.

MiscFilters: still hoping https://github.com/adworacz/zscene will be changed to not require an external call,...

I tested it and it works. Here an example of loading the SCDetect filter

vsutils_dir: str = os.path.dirname(os.path.realpath(__file__))
MiscFilter_dir: str = os.path.join(vsutils_dir, "..", "..", "..", "..", "..", "vsfilters", "MiscFilter", "MiscFilters")

def load_SCDetect_plugin() -> bool:
    """
    Ensures SCDetect VapourSynth plugin is loaded.
    """

    plugin_path = os.path.join(MiscFilter_dir, "MiscFilters.dll")

    try:
        if hasattr(vs.core, 'misc') and hasattr(vs.core.misc, 'SCDetect'):
            HAVC_LogMessage(MessageType.INFORMATION,"[INFO] Plugin 'SCDetect' already loaded.")
            return True
        else:
            vs.core.std.LoadPlugin(path=plugin_path)
            HAVC_LogMessage(MessageType.INFORMATION, f"[INFO] Plugin 'SCDetect' loaded from: {plugin_path}")
            return True
    except Exception as error:
        HAVC_LogMessage(MessageType.WARNING, "[WARNING] Plugin 'SCDetect': check/load failed ->", str(error))
        return False

The code is path-independent and does not explicitly use directory separators.

The code is path-independent and does not explicitly use directory separators.

MiscFilter_dir: str = os.path.join(vsutils_dir, "..", "..", "..", "..", "..", "vsfilters", "MiscFilter", "MiscFilters")

It assumes, a specific structure. (and names),
Just saying, I think this is unwise, since it only works with the current structure and will break in case I ever rename or move a folder, or a non-Window setup is used.
So just from a design point of view, I would advise against this.
From my point of view, it would be better to throw an error if those filters are not available, but needed.
It's your thing, I just wanted to give my input.

I'm not aware that HAVC is working also on not Windows OS, which are the supported OS ?

In such case could you privide the names of DLLs for the non Windows OS ?

Yes it is specific to Hybrid structure, so you should advise me in the case you decide to change it.
I provide an error in the case of loading error, so that the DLLs can be added manually in the script if needed.

I added this loading to be more free on which plugin load and use inside HAVC.
But the 2 approaches are not exclusive and can be used both.

Hybrid atm. does not offer torch add-on and similar on other OSs than Windows. (but this can be done )

Names depend on how you compile them to be named.

fine, by me, just wanted to note that it seems like a bad design.

Hello Selur,
  
    I added some changes to B&W methods (method 5 and new method 6) as shown below

:param BlackWhiteMode:      Method used by BlackWhiteTune to perform colors adjustments.
                                Allowed values are:
                                      0 : Apply Contrast Limited Adaptive Histogram Equalization on Luma (default)
                                      1 : Apply Simple Histogram Equalization on all RGB channels
                                      2 : Apply CLAHE on all RGB channels
                                      3 : method=0 and method=1 are merged
                                      4 : Automatic brightness and contrast optimization with ScaleAbs
                                      5 : Multi-Scale Retinex (HAVC)   <-- "on Luma" replaced by "(HAVC)"
                                      6 : Multi-Scale Retinex (B&W)    <-- new method #6

 I hope that you can release an updated test version.

Thanks,
Dan

Uploaded a new test version.

I was finally able to find a way to get colorful and stable video clips.

Here a sample using Retinex (HAVC version) + "Video+Artistic" (Constrained-Chroma merge, veryvivid) + tweaks

https://archive.org/details/young-franke...etinex.mp4

The combine method Constrained-Chroma is already able to filter-out most of flashing colors, but to get the best result is possible to add to the above settings the temporal stabilizer

Dan, these results are amazing!!!  A huge step forward.  I always thought there was something special about retinex, but it had many issues that now appear to be resolved.  
Looking forward for this to be released and reading the new user guide.

this retinex really gives good results
but why can't i load it in the hybrid preview

Whatever I do, I always get this error and it doesn't code accordingly
Maybe I didn't install something?

about Retinex: try installing Microsoft Visual C++ Redistributable 2013 Package
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.)
