Partially blended telecine - use srestore all the way?

I have a telecined source (film to NTSC) that is partially blended. Srestore followed by tdecimate does a good job fixing the blended parts, but what about the plain telecined parts?
How can I combine it with tfm to handle the full clip properly?

I don't think anyone can give you an answer unless you post a short sample.

If you don't mind going through and finding all the places where it's blended:

TFM.TDecimate
A=QTGMC.Srestore
ReplaceFramesSimple(Last,A,Mappings="[1000 2000] [10000 11000] [15000 16000]")###the frame ranges needing replacing

Surely you don't mean that? If you do then, yes, please post an untouched sample.

ReplaceFramesSimple is included in RemapFrames.

That sounds like SRestore's double-blend-removal mode, for fixing telecined sources that were blend de-interlaced instead of IVTC'd.
It doesn't automatically decimate.

Yes, perhaps you're right. I hadn't thought of that. The sample will tell the tale.

Here they are:

This is a blended part: https://www.mediafire.com/file/0t0sl...57/blended.mkv
I get good but imperfect results with this script
Code:
LWLibavVideoSource("blended.mkv").srestore(frate=23.976, omode="pp3", speed=-25).tdecimate(mode=1)

This is a plain interlaced part: https://www.mediafire.com/file/nu6hf...interlaced.mkv
I get perfect results with this script
Code:
LWLibavVideoSource("interlaced.mkv").tfm(order=1).tdecimate()

Your blended.mkv is interlaced so you don't want to use omode which is for something else entirely. In addition, setting a framerate when using omode does nothing - the framerate doesn't change. It's kind of messed up, I agree, but my script earlier might provide a good place to start, but with a slight modification:

TFM.TDecimate
A=QTGMC.Srestore(Frate=23.976)
ReplaceFramesSimple(Last,A,Mappings="[1000 2000] [10000 11000] [15000 16000]")###the frame ranges needing replacing

Bobbing + Srestore doesn't eliminate the blending entirely. Am I right to assume that this Bluray is impossible to fix completely?

It can't be entirely fixed as there are just too many blends. I'm pretty sure those blends are intentional and are a by-product of the dissolve effects created in that and (perhaps) other sections.

If they are intentional, you might just as well continue with the TFM/TDecimate you used on the rest of it as unblending doesn't improve it a whole lot.
