Hi, I am trying to erase these crawling lines. I had fairly good results, I would like to ask if it is possible to improve them.
Code:LWLibavVideoSource(".....Lines.avi", format="YUV420P8") ConvertToYV12() input=last AssumeTFF() TurnLeft() even = SelectEven() even = MergeChroma(even, even.DeScratch(mindif=255, maxgap=255, minlen=100, maxlen=2048, blurlen=50, keep=100, border=5, maxangle=0)).RemoveDirtMC(150) odd = SelectOdd() odd = MergeChroma(odd, odd.DeScratch(mindif=255, maxgap=255, minlen=100, maxlen=2048, blurlen=50, keep=100, border=5, maxangle=0)).RemoveDirtMC(150) Interleave(even,odd) TurnRight() StackHorizontal(input, last)https://forum.videohelp.com/threads/390085-Chroma-noise-removal-just-on-a-part-of-the-...eo#post2528319Code:LWLibavVideoSource("....Lines.avi", format="YUV420P8") input=last AssumeTFF() even = SelectEven() even = MergeChroma(even, even.deVCR(30)).RemoveDirtMC(150) odd = SelectOdd() odd = MergeChroma(odd, odd.deVCR(30)).RemoveDirtMC(150) Interleave(even,odd) StackHorizontal(input, last)

That's an extremely difficult problem to solve. You say that you "had fairly good results," but I see no improvement in any of the videos you posted.
I tackled a somewhat similar problem with floating noise bars on an amateur 1950s Kinescope. Here is the thread I started at doom9.org where I showed my problem clip and then, with a lot of help from StainlessS, was able to fix the problem almost completely (as you can see in the video above):
Bad 1950s Kinescope - Hopeless?
And here is a video showing the results I was able to achieve:
Your video has a very similar problem, but it may be difficult to track the noise bars using the same technique I used because they are more subtle than the bars I was tracking.

Don't get me wrong johnmeyer, I wrote fairly good not out of arrogance but because while pausing the video I saw a slight improvement. However, to see the flowing movement is a different story. I read your interesting Kinescope post, thank You for posting.

I don't think you will be able to get any improvement with that script because the artifact you are trying to remove is constantly moving and therefore requires a different approach than the one taken in that script.
