[HELP] Having a few problems
PAL DV 25fps to 29.97 1080i, interpolated etc. Crashing, files not completing etc.

Seems like a problem with the Vapoursynth script.

Looking at the Vapoursynth script:

Should work since only the width is adjusted (not the height) and Hybrid properly converted to YUV444P16 beforehand.

=> Does the Vapoursynth Preview work properly?

Cu Selur
The preview works fine, but then when I run the file it always crashes, Exit Status 0.
Okay, since the preview works fine, the Vapoursynth script in general should not be the problem.
Here a few things to try, to get to the bottom of the problem:
  • Does it work if you don't add the letterbox?
  • Does it work if you limit the thread count to 1 (Filtering->Vapoursynth->Misc->Script->Limit thread count)?
  • Does it work if you enable the 'Neo' option of FFT3DFilter?

Cu Selur
None of those options make a difference, it still crashes.
Does it work if you don't crop?
Okay, then try to disable filters until you see which filter is causing the problem.
Does this only happen with this source? (Does it work if you use a source you previously handled with Hybrid?)

Cu Selur
I will try another file tomorrow.
I switched over to SMDegrain, and it asked me to re-crop, then it worked fine. 

Perhaps the cropping needed for FFT3D is more sensitive to the crop/mod size?
Hmmm,... then the Vapoursynth Preview also should not work and throw an error. Huh
