FYI, I reported the Chroma Weight bug affecting 2022+ TVs to Dolby.
The last time I reported an issue(positive lift), I made it obvious that I was using third-party tools, and they never responded. This time, I approached it differently, and they did respond, so hopefully the bug is fixable rather than something baked into the newer SoC hardware.

Sweet! That would be awesome.

I've just updated to latest 3.1.2 version and new files in tools folder. For a while, when doing 6-2 plotting, I get a LavFilterSource error. I have stable 0.81 installed on my system, and recently extracted libs in tools folder. How can I mend this?

LAV Splitter Source not found.

Is this with or without cropping? Cropping can be tricky. I have two PCs with the same software and NVIDIA graphics cards, but I can only get cropping to work on one of them and can't figure out why. The workaround is to use ProRes, which is much faster anyway if you have a good CPU.

Have you tried re-installing lavfilters?
Also, you could try the latest nightly (https://files.1f0.de/lavf/nightly/LAVFilters-0.81.0-27.exe).

I've just pinpointed the issue: apparently 6-2 Plotter demands x86 LavFilters library. I had only installed x64.
With x86, it executed properly, except for a small python error in madvr_parser.py (one of the recent new files in the tools folder):
Traceback (most recent call last):

Thanks for this nice tool and all the hard work.
Is there a possibility to choose a different resize filter, when using 8-2 with the downscale option? Default is spline36.

[Kuler087]

it's in the screenshot settings
line 133
set upscale_algo=Spline36

Thanks, works ;)

Latest Beta (https://drive.google.com/file/d/128gq8aDUTKA_aT7SQsM9dkjA1EP1sosR/view?usp=drive_link), added a new frame-by-frame HDR plot method (SMITH-ZINK) in 6-2. Faster and includes an accurate auto letterbox detection for movies with variable AR, but values are calculated differently than madvr, and I personally prefer madvr.
example: https://slow.pics/c/0Zv5dLCI?canvas-mode=fit-width

Also added frame-by-frame plotting from madvr in 6-2, which is now the new default:

Hello Kuler087

1.What is the more accurate method for the screenshot?
HDR= 1 > SDR_DV_Trim_Pass= 3 > SDR_Libplacebo= 0
2.Is the SDR_DV_Trim_Pass pretty accurate?
3.I found a bug with "SDR_DV_Trim_Pass= 3". When there are multiple inputs only the screenshot of the last input are created.
I was using 3 inputs and it seems that input 2 overwrite input 1, and then input 3 overwrite input 2.
The same thing happens with "SDR_DV_Trim_Pass" when I use "Both= 2".
For "HDR= 1" and "SDR_Libplacebo= 0" work correctly.

[Kuler087]

1- DV trim, even if the input is just HDR10.
2- nothing is more accurate than it
3- strange, I do comps with 3 inputs all the time. Just did that yesterday in my latest YouTube video about The Day of the Dead. What are your 3 input formats?
4- I'll check it out but when i did it, it was working.

I am using DoVi Scripts v3.1.2
I don't used "auto mode" for the frames.
I change this setting to "set DEL_temp=NO"

[Kuler087]

ha ok, I never compare multiple HDR sources in SDR because I dont see the point. But I see the issue I introduced in the latest stable and the latest beta (https://drive.google.com/file/d/128gq8aDUTKA_aT7SQsM9dkjA1EP1sosR/view?usp=drive_link) should fix it.

This version requires many new files/folder and Python libraries. This version has new audio analysis options (6-8) and image comparisons viewer capabilities (similar to the slowpics website )

new python libraries to install: pip install pyyaml librosa scipy soundfile
new files/folder to put in the tools folder: https://drive.google.com/drive/folders/1CKLmJhbh0gbItC7auSHhFbwAYsJNp1Ml?usp=drive_link

Worked. Thanks.
Someone asked for this, but hope you can find an easy way to add the frame type to the "SDR_DV_Trim_Pass" screenshots.
