Hi, try some filter, put deinterlace, santiag, removegrain, deblock, In what order should I use them?
logically I put them as I wrote them...

Personally, I would use deblock after deinterlace or at least before removegrain to be sure the macroblock structure on which deblock filters work is as untouched as possible. But the 'best' order always depends on the source and the used deblocker. (i.e. machine learning based deblockers don't really work on the macroblock borders.)

Sometime I try tdecimate and srestore to put down the framerate at 23.976 from 29.97, seems working in some files, but after can I put up again the FR for original smoothness?
How can I understand if files are telecined?

You look for pattern if you bob the content, read: [INFO] Interlacing patterns

Quote:after can I put up again the FR for original smoothness?
You could add interpolated frames: "Filtering->Vapoursynth->Frame->Interpolation->Frame Interpolation" (on Mac, there are way less available methods for this, than on Windows, especially with a modern gpu and vs-mlrt or torch add-on).

Obviously: If you have a real 29.97fps source (with 29.97 unique non-blended frames) and you remove frames, you will lose motion smoothness and there is nothing you can do about it.

Here what I need to do with that separated fields (2 fields per block) ? Also bob dont have smooth

That does not indicate anything special and warrants no special handling.
I suspect the file is not interlaced, but telecined.
Look at what happens in the Vapoursynth Preview and compare it to [INFO] Interlacing patterns, then overwrite the scan type and adjust your interlace/telecine settings accordingly.

Ok make some test and maybe found solution...try telecine at 23.976 and then frame interpolation with rife with fps factor 5/2 to 59.94..

But why if select FFV1 always have file with PAR 3:2 also if select 8:9 or other format??  Huh

RE: What noise is that? - Selur - 28.06.2025

I wouldn't add the frame interpolation, but if you need that frame rate use it.
Quote:But why if select FFV1 always have file with PAR 3:2 also if select 8:9 or other format??
Hybrid reads the PAR using MediaInfo if the there is no 'Input PAR', Hybrid assume 1:1.
If you know your input PAR (= pixel aspect ratio) isn't detected properly, you need to let Hybrid know the correct value for it to work properly.
3:2 usually is a DAR not a PAR.
Can't produce the effect that FFV1 always comes out with a 3:2 PAR, here at all:

At me hybrid know 8:9 but become 3:2  Huh
