Help restore interlaced sped-up PAL DVD

[Paperweight]

Do you like Pink Floyd?
I own a DVD that I need to restore. A proper release is not available. It was originally in film (35 mm Mitchell Camera), then awfully encoded sped up to interlaced PAL (higher pitch audio too.) This is the only release available!
I am familiar with Avisynth but are there any gurus out there who can tell me the BEST way to make a slowed-down interlaced NTSC DVD out of this?

Not without a sample.

Also, slow-down *and* interlaced doesn't seem to make sense. If it went the route through a normconversion box, then it would be interlaced (fieldblended), but at original speed without speedup. When 24->25 speedup was used, then it shouldn't be interlaced.

Well possible that the only "interlacing" is the mpeg coding type.

Did you even look at it? It's not interlaced. It was only encoded as interlaced. For PAL just encode it as-is, perhaps after doing any filtering you might have in mind. Or don't, and keep the original PAL DVD.

For NTSC I slow such things to 23.976fps with an AssumeFPS(23.976) in the script, resize them to 720x480, encode them as progressive 23.976fps, apply pulldown, and then stretch the audio to match.

Around here we don't ask what's best, as there might be a number of valid opinions as to how something should be done. It's even in the rules:

Your sample is not interlaced, it's progressive PAL encoded as interlaced.
You may still want to apply
QTGMC()
SelectEven()
It improves the quality IMO.

Added:
You should also try
QTGMC(InputType=2)
or
QTGMC(inputType=3)
These modes are for improving flicker in progressive video, read here:
