Selur's Little Message Board

Hello, I encountered such a distortion in the video., an example from the link.
https://drive.google.com/file/d/1_7xgg6i...sp=sharing
QTGMC does not solve the problem.
Is there any way to fix it? What filters can I use? Thanks

That video was once interlaced, but then it was resized without taking into account that is was interlaced and then saved as progressive video. That video is messed up, only way to salvage it
Usual approach would be to: lower the resolution of the height till the lines are gone.
For example, try:

• loading source
  
• enabling Crop/Resize->Base->Resize
  
• enable "Filtering->Vapoursynth->Misc->Script->Lower res. before resize"
  
• enable "Filtering->Vapoursynth->Misc->Script->Lower res. before resize->height
  
• set the factor in "Filtering->Vapoursynth->Misc->Script->Lower res. before resize" to 2.
  
• check the Vapoursynth Preview to see the effect.

Thanks, everything is fine in the preview. Only the file is saved with the same problem. Maybe something needs to be enabled to encode?

Ah, Hybrid will skip Vapoursynth be default since you are only resizing and not using a special resizer.
->Enabling "Filtering->Vapoursynth->Misc->Script->Always use Vapoursynth" change that.
