[HELP] Processing speed
Can I do anything to speed up the processing of files which are around 5 - 10 minutes long, and are taking over 2 hours each to process? Is there anything in the filter order which I can change to speed up the processing?

Using a faster system.
  • Not totally sure whether it works on MacOS, but on Windows I would say try sending some of the work to the GPU, by:
    • changing: "Filtering->Vapoursynth->Misc->Source->Libav hardware decoding mode"
    • enabling "Filtering->Vapoursynth->Frame->Resize->NNEDI3->GPU"
  • moving the denoising and degrain above sRestore might speed it up.
Also I would not recommend using NNEDI3 when you are just resizing horizontally, since it seems like a waste of time.
With NNEDI3 you are resizing your input 1440x1080 to 2880x2160 and then to 1920x1080.
I doubt there is much of a gain using NNEDI3 in this scenario.

Thanks - removing NNEDI3 has cut 2 hours from the processing time.
