    Is it possible to remove such noise in the form of such diagonals over the main video? Maybe someone met with a solution to a similar problem.Image

  2. Use filter working in frequency domain (most likely founded around FFT) - if i recall correctly Avisynth has defreq

    Thanks for the answer ! Very useful information! I think it is necessary to do experimentation.

  4. First approximation with defreq:

    Code:
    ImageSource("Noise.png", start=0, end=23, fps=23.976) 
    Crop(1,3,-0,-0) # mod4
    ConvertToYV12()
    defreq(show=0, info=false, fx=18.9, fy=-4.5, sharp=4757.5)
