It is a small fragment of a video where you can see some intermediate frames with lines, which of the ways do you recommend me to diminish this effect.
What would you try to use in the first instance to mitigate it.

The original format is of very bad quality.
Thank you very much!

Following the indications of another post, the answer given by Selur also worked perfectly for me.

How about this?

You really did an excellent job. I really like the final result. I would like to know what path you took to solve it, I watched the video and it looks really good. It exceeded my expectations.

How about this?

It will probably take a lot of work to do the entire video -- you'll have to adjust the code for every break in the pattern. But here's what I did for the short clip:

LWLibavVideoSource("Movie interlaced.mov") 
src = last

BilinearResize(width,240).Spline36Resize(width,height)
p1 = Overlay(last, Loop(2,0,0), mode="Subtract", opacity=0.5).ColorYUV(gain_y=256, cont_u=256, cont_v=256)
p2 = Overlay(last, Trim(1,0), mode="Subtract", opacity=0.5).ColorYUV(gain_y=256, cont_u=256, cont_v=256)
p12 = Merge(p1, p2.Trim(1,0))
p12 = p12.SelectEvery(5, 1,1,1,1,1)

Interleave(src, p12)
SelectEvery(10, 0, 3, 5, 6, 8)
TDecimate()

# some temporal noise reduction may help here

ConvertBits(8) # for x264 cli

Believe me it is very helpful what you did, a great contribution, thank you very much for your time.
