MacOS Problem

[papioski]

Hello,
I successfully installed Hybrid on my MacBook Pro M5, but I am unable to perform the video preview process. I have had issues with VSPipe, even though I installed it using brew.
Despite being unable to preview, I was able to start the rendering process because I did not select a model from the frame section. Could you assist me?

Assist you, how?
Is Vapoursynth added to the PATH like the README.txt stated?
Hybrid does come with all the Vapoursynt filters (Hybrid.app/Contents/MacOS/vsfilters) I could find.
I can't really say whether those filters work on m5, but I expect them to.
It also comes with the scripts Hybrid uses (Hybrid.app/Contents/MacOS/vsscripts).
Does the Vapoursynth Preview show an error, if it does what error?
Where is the debug output? (seems like you ignored the notice to read the sticky,.. [INFO] Infos needed to fix&reproduce bugs,..)
If you want to use Vapoursynth, make sure the Vapoursynth Preview works.

I am experiencing a similar issue to the original poster.

What Hybrid version did I use?
Hybrid version 2026.03.21.1 (64bit)

What is used operating system?
macOS Tahoe (26.4.1) on Apple Silicon M5.

What did happen? If an error message came up what did it exactly say?
My goal was to deinterlace a .mov video using QTGMC and output it in ProRes format without audio. When I tried to run the job, the process crashed immediately during the video encoding stage (video sub-job).

Steps:

1. I followed the installation instructions exactly as described in the
   readme.txt file provided in this folder: https://drive.google.com/drive/folders/1...drive_link
   
2. I configured my paths as described in your guide here: https://forum.selur.net/thread-3.html
   
3. Loaded a .mov file. + the output path and file.
   
4. Set Filtering -> VapourSynth -> QTGMC enabled.
   
5. Set Video Handling to ProRes and disabled audio export.
   
6. Added to Queue and started the job.
   
7. The job crashes instantly.
   

Other:
I also noticed that the video preview in VapourSynth is not working (screenshot attached).
I am unsure what the correct 'official' path is that needs to be configured in the VapourSynth Editor settings to make it function correctly on this system.

Hybrid uses and should come with vsViewer,...

The Vapoursynth script:

core = vs.core
core.std.LoadAllPlugins('/Applications/Hybrid.app/Contents/MacOS/vsfilters')

seems fine.

Ahhh,...

AttributeError: No attribute with the name nnedi3cl exists. Did you mistype a plugin namespace or forget to install a plugin?

ahh,... disable the GPU in QTGMC
I thought I bundled nnedi3cl with Hybrid.

/opt/homebrew/lib is the path vsViewer points to here,.

Thank you for your response. Could you please clarify exactly where the GPU setting should be disabled? I am unable to find this option under the Filtering -> (De-)Interlace/Telecine tab, for instance.
