Removing interlace artifacts from progressive scan video

[mathiassk]

Hey, Iv'e been trying to restore this video for days without success and I hope someone here can help me, if it's even possible. The source file is from a spanish TV broadcast from 2005 downloaded from the internet many years ago, and it seems it has been converted to progressive scan without being deinterlaced first. As you can see it suffers heavy from compression and interlace artifacts and I was hoping someone could take a look and see if there's any way of making it look better? I have avisynth and virtualdub2 but I'm I newbie, so there's a lot of technical stuff I don't understand. I'm only interested in the concert footage from 6:57-13:16 but restoring the whole file won't hurt either

As a last resort, you could resize vertically (keep horizontal resolution) until the combing lines are gone and then upscale to your source/target resolution to get rid of the combing artifacts, but you will mess up the hard-coded subtitles, and you will lose details (especially in more static scenes).

I'm only interested in the concert footage from 6:57-13:16

then the resizing might 'work', but you will still lose (lots of) details

=> I would recommend looking for a better version, to start out with,...

Thank you, that's kinda what I ended up doing. I did some more trial and error and ended up with a better result than the source, in terms of interlace artifacts.
If anyone are interested for similar issues, I used these settings:

SetFilterMTMode ("QTGMC", 2)
FFmpegSource2("2004 11 11 - SOL, Badalona, Barcelona, Spain [AVI] [82.6 mb].avi", atrack=1)
Spline64Resize(480,196)
AssumeTFF()
Spline64Resize(480,392)
QTGMC(InputType=2)
Prefetch(10)

Unfortunately there's no way of finding a better source, but I'm pretty happy with the result anyway
