Hybrid 2025.11.09.1 - No module named 'havsfunc' - DCCentR - 04.03.2026
Hi,
When I click the Vapoursynth preview button, I get an error:
Failed to evaluate the script: Python exception: No module named “havsfunc” Traceback (most recent call last): File “src/cython/vapoursynth.pyx”, line 3378, in vapoursynth._vpy_evaluate File “src/cython/vapoursynth.pyx”, line 3379, in vapoursynth._vpy_evaluate File "C:\Users\Goryunov\AppData\Local\ Temp\tempPreviewVapoursynthFile13_06_03_422.vpy“, line 16, in import FrameRateConverter File ”C:\Program Files\Hybrid\64bit\vsscripts\FrameRateConverter.py", line 98, in import havsfunc as havs ModuleNotFoundError: No module named “havsfunc”
I am using: Filtering > Vapoursynth > Frame > Interpolation > Frame Interpolation (FrameConverter)
I tried changing “import havsfunc as havs” to “import havsfunc_org as havs” in FrameRateConverter.py, after which Vapoursynth preview started to run.
I don't know how correct this was, but it seems to have helped

Try latest dev.
Instead of havsfunc misc should be used.
=> replacing the FrameRateConverter.py with https://raw.githubusercontent.com/Selur/VapoursynthScriptsInHybrid/refs/heads/master/FrameRateConverter.py
should fix it.
