#croping

#resizing Lanczos4Resize() or Spline36Resize()

super = MSuper()
backward_vectors = MAnalyse(super, isb = true)
forward_vectors = MAnalyse(super, isb = false)
forward_compensation = MFlow(super, forward_vectors, thSCD1=500) # or use MCompensate
backward_compensation = MFlow(super, backward_vectors, thSCD1=500)
interleave(forward_compensation, last, backward_compensation)

Checkmate()
VagueDenoiser(threshold=1.2, method=1, nsteps=6, chromaT=0.8)

RemoveSpots() will remove many spots that appear in only one frame.

RemoveSpots() works good. it's removes the most of the spots but it's missed some spots.

any idea about using multible times.. for full spot removable.?

RemoveSpots().RemoveSpots() ..?

it can't removes moving areas..

You can call RemoveSpots() multiple times but you'll start noticing image degradation. Most of the spots that RemoveSpots() misses are in moving parts of the picture. It only works well on still parts of the frame. There is a motion compensated version around that might work better. Look for RemoveSpotsMC().

RemoveSpotsMC() not removed motion area spots..

RemoveSpotsMC() not removed motion area spots..

You can try using something like ReplaceFramesMC(), also know as RX(), to create a new frame based on the two surrounding frames. Or that in conjunction with manually created masks. Or copying bits from other frames manually.

Also, make sure you video doesn't have duplicate frames. Remove spots won't work if the same spot appears in two successive frames.
