In the MediaFire link in the signature of StainlessS. In the DATA folder there, I believe.

I am not 100% sure what madVR does in "film mode".
Anyway you do not need inverse telecine for Pal DVD's.
Did you try to disable deinterlacing for DVD's?

Yes I tried, just now I'm watching a dvd. And I can't see any difference. How possibile?

I thought I need it.

Lav reads that the file is interlaced so send this info to madvr. I think it works this way.

In fact madvr says, deinterlacing on (says upstream).

Many thanks!

@Ruler FYI, your C32HG70 monitor is not a real 10-bit but, 8-bit + FRC. Apparently, you need a Quadro or Radeon Pro to support it. Literally, no consumer (GeForce/Radeon/Intel) GPUs support true 10-bit rendering.

Asmodian · 23rd February 2018, 08:00

No, madVR can render in 10-bit perfectly well on almost any GPU out now but only when fullscreen. Both Nvidia's and AMD's standard consumer GPUs can output 12-bit to anything that supports it.

I also have some questions regarding deinterlacing/IVTC in MPC-HC with madVR:

1. What is generally better quality, GPU deinterlacing (NVIDIA 1050Ti) or software (YADIF)? If both are equal, which option is more efficient and lets me spend more GPU resources for upscaling etc.?

2. If I choose Software deinterlacing (YADIF), and it is active e.g. for an interlaced PAL DVD, madVR reports the correct framerate (50fps) but tells me "deinterlacing off". Why?

3. If I choose Software deinterlacing with an IVTC source, what exactly happens? Does YADIF correctly perform IVTC or does it (wrongly?) deinterlace? I am asking because there seems to be no way to activate IVTC in madVR because YADIF already sends the double framrate to madVR.

4. IIRC, native D3D11 decoding cannot be used with GPU deinterlacing. But can it be used together with Software (YADIF) deinterlacing?

Thank you for helping me out!

huhn · 23rd February 2018, 09:51

1. there is no general answer to that at the moment nvidia deinterlancing is broken and really bad but that doesn't mean it will always looking worse than YADIF.

2. because the source is already deinterlaced no need to deinterlance a deinterlaced source.

3. it get's deinterlaced so no it doesn't get IVTC and sources are either telecine, PsF or interlanced.

4. d3d11 >native< doesn't support hardware deinterlancing and doesn'T work with software deintelrancer d3d11 copyback works fine with YADIF.

Thank you. But what are the "side effects" (if any) of incorrectly deinterlacing IVTC content? Does it lead to artifacts?

About the Progressive Segmented Frame (PsF): How do I recognize that a source is PsF and what is the correct way of handling this source? Deinterlacing on/off or IVTC?

Use 10bit. (My TV panel also 8+frc and I also use 10bit.)

huhn · 23rd February 2018, 10:47

a really good deinterlancer doesn't harm PsF it just doubles the frames with "perfect repeats" soy ouz just loose performance.

on a PsF source everything can produce correct results IVTC (by doing nothing), disabling deinterlancing and a really good deinterlacer will just double frames. disabling will always produce the best results if the whole source is PsF with no exception and no strange pattern like 4:2:2:2 else IVTC a really good IVTC is better madVR IVTC is limited in this example (frame times are not corrected).

and again there is no IVTC content there is telecine.
the big benefit of a IVTC algorithm is that it removes judder from the source something a deinterlacer can't do(it'S not made for it). NTSC is know for 3:2 cadences.

so the artifacts you get by deitnerlacing a telecine source is judder for 3:2 sources if the deinterlacer is really good or you will get all kind of known deinterlacer artifacts.

for Psf DXVA or YADIF are neither really good. DXVA was in the past really good for this.

I learned that often pal dvd are encoded as interlaced but they come from progressive source. So deinterlacing is not needed.(here @huhn comes to kill me

)

Aside of my eyes how I could configure properly my dvd profile? There is some value I have to look at and that I can use as rule for my profiles?

So actually my lav read a movie is encoded as interlaced and madvr starts deinterlacing also when it doesn't need it.

So... how can I check if a content is really a source progressive and doesn't need deinterlacing? In particular with dvds.

-sTi- · 23rd February 2018, 17:11

So a DVD flagged as "interlaced" can either be truly interlaced (=> deinterlacing must be on), PsF (=> deinterlacing must be off) or telecined (=> deinterlacing must be off, IVTC on)
This interlacing stuff is killing me...

nussman · 23rd February 2018, 17:16

I am using a hotkey so switch between deinterlaicng (GPU) and deinterlacing off for progressive sources (most Pal DVDs)
Dont think this can be done automatically.

Yes but IVTC is not needed on pal dvds.

You mean deinterlacing when you say interlacing? Can you clarify this?

Maybe not in general, but I have a feeling someone will come along soon and provide us with an exception for this rule...

Yes, and I was thinking. If a dvd is encoded as interlaced but it's basically from a progressive source, and I can play it fine on my monitor without deinterlacing.

What happens when this DVD is played inside a DVD player (with or without deinterlacing support) on an Interlaced monitor/tv?
