[HELP] NTSC SD master, best De-Interlace?

[Miranda]

I would suggest:
Bob the content i.e. using "Filtering->(De-)Interlace/Telecine->QTGMC Vapoursynth->Bob" and look at the output in the Vapoursynth Preview.
If each frame shows motion, the source is telecined, if you see a 3 frames with motion 2 identical ones the source is telecined.
If you see something else the content probably is some mix of interlacing, telecine and progressive fields.

Assuming your content is interlaced use "Filtering->(De-)Interlace/Telecine->QTGMC Vapoursynth->Bob" with Preset 'Slower', depending on the source using preset 'Custom' and adjusting the settings might also help to get a bit more quality.

Assuming your content is telecined:

• enable "Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine->Overwrite input scan type to" and set it to "telecine"
  
• then try "TIVCT (Vapoursynth)" and "VIVTC (Vapoursynth)"
  
• if your content has mixed 3:2 pattern, keeping the content als bff, bobbing with QTGMC and using sRestore to get to 23.976 might help.
  

If you got some residual combing "Filtering->Vapoursynth->Frame->Vinverse / Vinverse2" might help.

Regarding the moire pattern: I would need a small sample which shows the issue to recommend anything.

The video is a feature film, would that not indicate that it was telecined to video?

ps - congrats on the software, it's incredible.
