I'm pretty much tearing my hair out here so any advice/tips are very much welcome.
Is it OK for you ?

I'm a bit rushed so I can't check the whole thing frame by frame now, but the scene change you mentioned seems to be duplicate free if you do this:

TFM(micmatching=0).TDecimate()

I think there's telecine each side of the scene change, and possibly an orphaned field or two (shoot me if I sound like Katie), and maybe in an attempt to make it a whole frame TFM is trying too hard to find a matching field, so when it does it creates an extra duplicate frame instead of dropping the orphaned fields. Or maybe that's a load of bullocks....

Thank you for taking the time! I went through your clip frame-by-frame, and found only two instances of frame duplicates (at 00:27.110 and 00:44.169), neither of which were in the tricky section I described. Very promising indeed! I'll process the entire video with micmatching disabled and we'll see what happens. Thanks!

00:44.169 is the last frame, so I'm not sure it should count, especially as the video was cut at the end.

It looks as though the duplicate frame around 00:27.110 might have been a decoding oddity. I've decided to pretend it didn't happen once I've finished typing this post, but I couldn't work out why there was a duplicate frame encoded, yet I couldn't see one looking at the script, until I remembered I indexed and decoded with ffms2 last time and Lsmash this time, so I tried ffms2 again and sure enough, the duplicate frame re-appeared. Back to Lsmash, no duplicate.

I'm using XP compatible versions of lsmash and ffms2, so hopefully it's just an "old ffms2" thing.

Yeah, good point.

I'll stick with Lsmash then; should have time to finally test this out today. Thanks!

Why old? ffms2 C plugin XP compatible was last updated on the 3rd of May 2020 here: https://rwijnsma.home.xs4all.nl/files/ffms2/
You'll find next updated builds on that website.
Reino keeps both ffmpeg and ffms2 updated and XP Compatible.

Not only XP compatible, Reino's builds do not even require a SSE2 capable CPU. Plus these builds are extremely well tested and totally reliable.

Now that the Zeranoe forum has disappeared it is a little bit hard to find Reino's builds. I hope that he will open a new thread about his builds right here at Doom9...

FranceBB,
Methinks that you are just the guy to maintain thread/list of all things XP compatible,
wadya think HH, is he the guy ?

For some unfathomable reason LSMASH refuses to open the source .m2ts. I can't understand why. An issue with Staxrip 2.1.1.4?

LWLibavVideoSource opens it fine, but micmatching=0 doesn't produce the results I hoped for: a duplicate frame raises its ugly head at 00:21.355. Did not bother to check the rest of the file, tbh.

Tested DSS2 as a source filter; opens .m2ts fine but same duplicate frame pops up. I even gave VapourSynth a shot, with VFM and VDecimate, to a horrible result of duplicate frames everywhere.

LSmashVideoSource is for ISO containers only, according to my list M2TS is not type ISO.
Code:
    Function IsISOFileName(String s)        {s=RT_GetFileExtension(s) Return(s==".mov"||s==".mp4"||s==".m4v"||s==".3gp"||s==".3gpp2"||s==".3g2"||s==".mj2"||s==".dvb"||
                                            \ s==".dcf"||s==".m21"||s==".m4a"||s==".m4b"||s==".m4p"||s==".k3g"||s==".jpm"||s==".jpx"||s==".mqv"||s==".ismv"||s==".isma"||s==".f4v")}

Enabled Display option for TDecimate to see what the heck it was doing, and discovered that TFM is outputting duplicate frames that break the cadence which seems to confuse TDecimate. In the attached pic you see six duplicates instead of five in a 25 frame cycle, and TDecimate leaves duplicate frame 636 in.

I think you've already tried increasing the cycle size for TDecimate, but have you tried giving it total discretion? You could try mode=7 first, but mode=2 on a second pass is sometimes a little better.

1st pass:
TFM(Output="TFM.txt")
TDecimate(Output="TDecimate.txt", Mode=4, rate=24.0/1.001)

2nd pass:
TFM(Input="TFM.txt")
TDecimate(Input="TDecimate.txt", Mode=2, TFMIn="TFM.txt", rate=24.0/1.001)

You sure it's not the broken cadence that causes TFM to create an extra duplicate frame when it has to rather than it being the other way around. If the cadence keeps changing, TFM can't do more than work with what it's given, so to speak.

Before this moment I was complete oblivious to it. I've done my ffmpeg shopping there for quite a while, but never thought to move away from that page (I bookmarked it) and browse the other aisles.

Cheers.

Yeah, I've tried various cycle sizes, and also mode 2 as well. There's been so many variations that I can no longer remember which mode I used when doing 2pass like you outlined. I'll give it a shot regardless.

You're right; I can't be sure what's causing the extra duplicate(s) that break the cadence so TDecimate can't do its job. To be honest, I would not be surprised to learn that the original has somehow been borked in production.

You can try use some filters from "Duplicate Frame Detectors" after "Tdecimate", to remove remaining duplicate frames.

Sure, but simply dropping the dups would mess up the frame rate.

I'm running TDecimate 1.0.4 in Staxrip 2.1.1.4, with display=true. While most frames give values like "53.94 182819" and "1.03 3485", every now and then I see things like "5442416468121445.00 18446744073709551615" which feels like it can't be correct.

Since nobody is mentioning it, for those who don't have Github Notifications turned on, I'm gonna say it: Ferenc released a new version of TDeint (v1.7) to address an high bit depth issue related to edeint. https://github.com/pinterf/TIVTC/releases
