Updated the torch add-on download to include v5.6.1.

Since HAVC uses CLAHE, have you tried using zsmooth instead of cv2 for it?

No, but cv2 should be already optimized being written in C/C++.
In any case in the coloring pipeline, the bottleneck are elsewhere.

For example, recently I had to perform some color adjustment on a 1440x1080 clip already colored, using this code

Code:
clip = havc.HAVC_ColorAdjust(clip=clip, BlackWhiteTune="strong", BlackWhiteMode=4, BlackWhiteBlend="True", ReColor=False, chroma_resize=True)

clip = havc.HAVC_ColorAdjust(clip=clip, BlackWhiteTune="medium", BlackWhiteMode=3, BlackWhiteBlend="True", ReColor=False, chroma_resize=True)

The encoding speed was about 30fps and in this case are used both LUTs and CLAHE.
I admit that is not very fast, but given that in this case the CPU usage was 25% and the GPU usage was 9%, I think that the best option to increase the speed is using the chunk encoding as suggested in the chapter 4.0.4 of HAVC user guide.

I tried to use Filtering->Filter Order/Queue->Use Filter Queue
To build a script calling 2 times HAVC_ColorAdjust, using these settings

[Image: attachment.php?aid=3364]

The expected code to be generated is

Code:
clip = havc.HAVC_ColorAdjust(clip=clip, BlackWhiteTune="strong", BlackWhiteMode=4, BlackWhiteBlend="True", ReColor=False)

clip = havc.HAVC_ColorAdjust(clip=clip, BlackWhiteTune="medium", BlackWhiteMode=3, BlackWhiteBlend="True", ReColor=False)

But Hybrid instead of generated the following code

Please, could you fix it.

Thanks,

Will look at it after work and try to reproduce it.

Had quick peek at it before work:
BlackWhiteBlend="True" doesn't show up, since it's the default.
chroma_resize=True <= that is an unknown option to Hybrid.
I will look into why 'BlackWhiteMode' isn't there.
Looking at the FilterQueue entry 'vsColorAdjustBWMode;ScaleAbs - LUT' is listed.
Okay, it was a mistake where I used:

Code:
if (this->getBool("vsColorAdjustBWTune", parameters)) {

instead of

Code:
if (this->getString("vsColorAdjustBWTune", parameters) != "none") {

=> Uploaded a new test version which should create:

Code:
# stabilize colors using ColorAdjust (HAVC)

clip = havc.HAVC_ColorAdjust(clip=clip, BlackWhiteTune="strong", BlackWhiteMode=4, ReColor=False)

# stabilize colors using ColorAdjust (HAVC)

clip = havc.HAVC_ColorAdjust(clip=clip, BlackWhiteTune="medium", BlackWhiteMode=3, ReColor=False)

as expected.

Now it works as expected.

Thanks,

"No clue" from me without a debug output.
Maybe Dan has an idea

Please provide the full script generated by Hybrid.

Assuming the folder exists and holds the expected files, the call:

Code:
clip = havc.HAVC_main(clip, EnableDeepEx=True, DeepExMethod=3, ScFrameDir="E:/Colorization NEW/Mahamantri Timmarusu/new colour/akvis", DeepExModel=0, DeepExEncMode=0, DeepExMaxMemFrames=0)

seems fine to me.
