Concerning horizontal line color.mpg the grey lines defect stays/moves across a large number of frames, is difficult to repair it.

Using FixRipsp2() 4 times I was able to obtain this, not satisfying for all frames:

some small result:

bad result:
Attachment 14141

Here the script, it's very "heavy, you may want to split the operations using only 2 FixRipsp2() calls at the time:

Code:

# interlaced  fields TFF

# problem: horizontal stripe

# solution: repair with FixRipsp2



# FFmpegSource

loadPlugin("C:\Users\giuse\Documents\VideoSoft\MPEG\AviSynth\extFilters\ffms2_87bae19\x86\ffms2.dll")



#video_org=FFmpegSource2("horizontal line color.mpg")

#video_org_trim=video_org.trim(10,100)



video_org_trim=AviSource("1_rep_sequence.avi").convertToYV16()



# plugins directory

plugins_dir="C:\Users\giuse\Documents\VideoSoft\MPEG\AviSynth\extFilters\"



        # FixRipsp2

Import(plugins_dir + "FixRipsp2.avs")

        # RgTools

loadPlugin(plugins_dir + "RgTools-v1.0\x86\RgTools.dll")

         # DePanEstimate

loadPlugin(plugins_dir + "depanestimate110\DePanEstimate.dll")

        # FFTW

loadPlugin(plugins_dir + "LoadDll\LoadDll.dll")

loadDll(plugins_dir + "fftw3_20040130\fftw3win32mingw\fftw3.dll")

        # DePan

loadPlugin(plugins_dir + "depan1131\DePan.dll")

        # MaskTools2

loadPlugin(plugins_dir + "masktools2-v2.2.23\x86\masktools2.dll")

        # MVTools

loadPlugin(plugins_dir + "mvtools-2.7.41-with-depans20200430\x86\mvtools2.dll")



### separate fields

video_org_trim_sep=video_org_trim.AssumeTFF().separateFields()



### select even fields

video_org_trim_sep_even=SelectEven(video_org_trim_sep)



### select odd fields

video_org_trim_sep_odd=SelectOdd(video_org_trim_sep)



### repair

video_org_trim_sep_even_rep=video_org_trim_sep_even.FixRipsp2().FixRipsp2().FixRipsp2().FixRipsp2()

video_org_trim_sep_odd_rep=video_org_trim_sep_odd.FixRipsp2().FixRipsp2().FixRipsp2().FixRipsp2()



### interleave

video_interleaved=interleave(video_org_trim_sep_even_rep,video_org_trim_sep_odd_rep)



### weave

video_restored=video_interleaved.Weave()



return(video_restored)

For a similar problem on a file captured by a friend in the past, we also experimented a frame by frame restoration with Photoshop, where you can rebuild the corrupted lines from adjacent lines or lines from previous frames. Result was better but still not excellent. The first frames were good, but in the latest the proportions in the body of the girl and the table were altered. If you switch fast between the 2 images you will see. More work would have been required!

good result:

bad result:

thank you very much sir, you are the best ^^

Not really, I did not solve the problem.

About the bad frames in the third video a quick fix is replacing them with previous or following frames (very basic AviSynth script). Some frames have bad color, must be fixed with restoration.

Code:

loadPlugin("C:\Users\giuse\Documents\VideoSoft\MPEG\AviSynth\extFilters\ffms2_87bae19\x86\ffms2.dll")



video_org=FFmpegSource2("bad frames.mp4")



video_frames_replaced=video_org.trim(0,34)++video_org.trim(34,34)++video_org.trim(36,37)++video_org.trim(37,37)\

                    ++video_org.trim(39,116)++video_org.trim(116,116)++video_org.trim(118,129)\

                    ++video_org.trim(129,129)++video_org.trim(131,209)++video_org.trim(209,209)\

                    ++video_org.trim(211,303)++video_org.trim(303,303)++video_org.trim(305,316)\

                    ++video_org.trim(316,316)++video_org.trim(319,319)++video_org.trim(319,409)\

                    ++video_org.trim(409,409)++video_org.trim(412,412)++video_org.trim(412,492)\

                    ++video_org.trim(492,492)++video_org.trim(494,585)++video_org.trim(585,585)\

                    ++video_org.trim(587,597)\

                    ++video_org.trim(597,597)++video_org.trim(599,599)++video_org.trim(599,599)\

                    ++video_org.trim(601,610)



return(video_frames_replaced)

Result here: Attachment 14150

thank you very much sir
