How can deblend this ?

[Selur]

ReduceFlicker(clip, strength=3, aggressive=1) seems to work fine with the flickering.
This script seemed to work fine for me.
Filters I used are:

• TIVTC for the combing
  
• ReduceFlicker for the flickering
  
• Crop for the black bars
  
• Checkmate for some of the dot crawlers (especially on the right side of the frame)
  
• RainbowSmooth for the rainbows
  
• (edge masked) BasicVSR++ to fix the general edges
  
• LumaSharpen to emphasize the edges
  
• YAHR to lessen the white halos
  
• Resized to 1:1 PAR
  
• Santiang to remove staircasing artifacts on edges.
  

There are still rainbows in a few frames, but nothing that annoys me.
