Hi Selur, I'm trying to get DDColor and vsdeoldify working on CachyOS Linux (Arch-based).
My setup:
  • Hybrid 2025.11.09.1
  • VapourSynth R73 (installed via pacman/AUR)
  • Python 3.12.13 (installed via AUR as python312)
  • vsdeoldify 5.6.5 and vsddcolor installed in ~/.local/lib/python3.12/site-packages/
  • RTX 5080, CUDA 13.2, PyTorch 2.11+cu130
  • misc.ini has: pythonPath and vsScriptPath set correctly
Hybrid detects VapourSynth correctly (log shows "-> detected Vapoursynth") but then removes DDColor, DeOldify and HAVC during the VapourSynth tab initialization. No VapourSynth tab appears in the UI.
What does Hybrid check specifically to decide whether to show DDColor/DeOldify? Is there a specific file or package it looks for?

Hybrid atm. does not support any of the torch- or vs-mlrt based filters on Linux or Mac.

If the Vapourynth-tab itself isn't available, Hybrid didn't detect Vapoursynth properly. (What does Hybrid output if you start it from a terminal?)
That no entries in the Vapoursynth-tab to DDColor, DeOldify and HAVC exist is as expected.
