Need help with deinterlacing, frame blending and color correction.

[Selur]

In general about blends for interlaced content:
a. if the separated fields are not blended and the blending is caused by the deinterlacing, trying different settings or something like QTGMC+sRestore helps
b. if the separated fields are already blended, only usually tried to lessen the blending in the fields by separating them and applying some denoising&co on the fields, then weave the content back together deinterlace and may be denoise some more and maybe even remove frames with sRestore or similar.
c. if the blends are everywhere, but there are enough good frames, bobbing and removing frames might work too

To filter separated fields, you need to set "Vapoursynth->Misc->Script->Filter interlace handling" to 'separate fields' and move any filter that should be applied on the separated fields before the deinterlacer.

here's an example (which is rather slow) where I:

• separted the fields
  
• applied SpotLess
  
• applied BasicVSR++
  
• combined the fields again
  
• deinterlaced the clip
  
• applied temporal stabilization
  
• reduced the frame rate using RIFE (yes, RIFE can be used for frame reduction too)
