How can I erase this interlace line?

[dvdcodek]

[I am not an English speaker, and my knowledge of encoding is short]


I'm currently encoding this classic bluray video.
I have attached the sample below.

Even if I use QTGMC or YADIF
interlace line will not be erased.




Any ideas to erase this?



thanks for read this post. have a good day

If you look at the separated fields, you still see combing artifacts in the fields. => normal deinterlacing won't help there.
Looks like someone wrongly resize interlaced content, and resaved it as interlaced content.
You will probably have to separate the fields, filter the fields, then weave them again and deinterlace.
(ugly solution: don't deinterlace, downscale horizontal until lines are gone then upscale to the original resolution)

Less ugly than what you have now. Experiment with some of the descaling options , upscaling options

LWLibavVideoSource("cut.ts")
ConvertToYV16()
DeSpline16ResizeMT(1920,486, order=2, accuracy=2)
AssumeTFF().QTGMC(preset="faster", sharpness=0)
LanczosResize(1920,1080) #or whatever upscaler

Thank you. I learned something new!
It will help me a lot to deal with the problem

Your care is perfect!

My knowledge is not enough to add anything right now!
I'll study a little more and give it a try!

I have a question.
When I try to encode,
megui will force it to add the following color conversion script,
Is it okay to put this in and encode it?

ConvertToYV16()
DeSpline16ResizeMT(1920,486, order=2, accuracy=2)
AssumeTFF().QTGMC(preset="slower", sharpness=0).selecteven
LanczosResize(1920,1080)
crop(240, 0, -240, 0)
ConvertBits(8)
ConvertToYV12()

It's ok - but SelectEven() drops every 2nd frame - 29.97p instead of 59.94p . Motion will be less smooth.

The original before the BD upscale was interlaced - 59.94 fields/s . So when you properly deinterlace - you should get 59.94 to retain the motion
