Mixed interlacing and frame blending – workflow recommendations?

[Selur]

Small follow-up on the second sample.

I just remembered, I made a port of Avisynths AutoChromaFix a while ago.
Which automatically adjusts chroma shifts, I did a with your second source and it worked fine.

So you could:

• save https://pastebin.com/YtP0mP0R as autoChromaFix.py into your 'Hybrid/64bit/vsscripts'-folder
  
• load your second source in Hybrid
  
• overwrite the input frame rate to 29.970029 (Filtering->Misc->Overwrite Input->Frame rate)
  
• overwrite the content scan typt to 'telecine' (Filtering->(De-)Interlace/Telecine->Overwrite scan type)
  
• Create a custom section behind the deinterlacer, by using 'Filtering->Vapoursynth->Custom->Insert before->ReplaceBlackFrame' and adding
  
  import autoChromaFix clip = autoChromaFix.AutoChromaFix(clip, nodisplay=True)
  inside the text field.
  

This way the first scenes:

and the second scenes:

chroma are fine, without having to adjust the chroma shift per scene.
General cleaning of the source shouldn't be an issue: https://www.mediafire.com/file/a5hqjjwdx...d.mp4/file
