[HELP] Having a few problems

[Selur]

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?
