Case closed
I have put no software deinterlacing in LAV and now there are no more repetead frames and movie info in madVR shows 25fps instead of 50 fps.

all mepg2 dvds are interlanced i can only guess that this DVD doesn't need an deinterlancer and works fine without. but that a guess.
media info is not 100% reliable.

the repeated frames are still a bug "somewhere"

if it is in madVR or lavfilter is sending work frame times or if the file is "broken" i have no clue.

Is there a flag for 3D that can be used to pick profiles? I didn't see anything in the 3rd post. I see HDR, but no 3D.

Or is there some other way to identify when madVR switches to 3D (frame packed) output?

Edit: 3D is a valid boolean value for profiles. The profile guide in post 3 is outdated.

I tried making a custom refresh rate with nvidia and the 3d got amazingly messed up. I gave up on the Nvidia at this point as I'd like to be able to try DTSX and Atmos and they need to bitstream with 23.976.
Reclock cant adapt 23.976 to 23.971, it hasnt such an option (usually its 24 or other STANDART refresh rate).
And 24fps movie + 23.971 refresh rate = drops

You are quite right, super-xBR + SR1 is very nice, I think I will switch to super-xBR 100 + SR1. I had tested super-xBR for chroma when it was first added but with the current SR1 I like the look of super-xBR for chroma upscaling a lot more. Thanks.

Reclock adapts the audio to your actual measured refresh rate. This is why it has its video clock database that you can clear, it is constantly measuring and updating the audio speed adjustment to keep everything in perfect sync. Watching 23.976 video on a 23.971 Hz display, without frame drops or audio skips, is what Reclock is for.

As far as I know there are no 24fps movies, I have never seen one anyway. Almost everything is 24/1.001 fps.

With classic blu ray you must activate the HDR functions madVR or not?

NP. Hope you ticked AR. I still think SR1 is a tad over the top with chroma and prefer to just notch up to 125 myself.

than we have interlanced content that is PsF and don't need a deinterlancer.
and we have telecine which is 24 frames on 60 fields (and other stuff) the film mode in lavfilter is not restoring these the film mode in madVR is.

if the source is telecine a IVTC (film mode) algorithm is clearly better.

50i usually needs a deinterlancer or can be treated progressive.
Yes, thanks for the correction.

Classic Blu-rays are not HDR, so you do not need to do anything there.

Of the top of my head, Yip Man (2008) is 24.000 fps, and I recently watched 5 to 7 (2014), also 24fps, there were others, can't remember now.

There are.
Some regional blurays outside of North America and UK will sometimes transfers movies in 24fps.

Yep. Don't forget that 23.976 fps only really exists because of legacy reasons. Films are usually shot at 24 fps and some are transferred to BD like that.

Honestly, I feel chroma Bicubic 60 AR paired with image Jinc AR is a good combination. The image doesn't get oversharpened, and the colour has a smoother almost creamier tonality to it.

A video test I believe that helps prove this is the first few seconds of the opening of the movie the Revenant. The entire movie is filmed in natural light. The bit where the boy is backlit by the flames, with bicubic 60 AR you see a soft red glow around him on the ground. With some of the other chroma algos this glow seems to be faded or less saturated.

I'm fully aware of that. I have been for a long time but it's good to let others know.

How bad are these videos?

The first thing you should be doing is viewing high bitrate videos, I keep mine on low, set a shortcut to change it if the source requires.

On 720P I usually just upscale with NNEDI3 (which doesn't make that much of a difference on a 1080 screen TBH) downscale with SSIM 1D without AB maybe do some reasonable SE and CE sharpening and that's it. Line thinning was kinda useful on some soft ~640x480 anime I had but it even at lower settings in some areas didn't produce good results which is why I asked madshi about adding warpsharpen to madvr which is considerably better for anime.



Link me a sample file that you feel your settings look good on and upload your settings.dat and I'll do a screenshotcomparison vs what I would use.
I might be able to make you reconsider what is considered good image quality.



Madshi, would it be possible to add to madVR the ability for it to remember settings for certain videos?

For example if I watch a video that has poor color and lots of banding and I hit a couple of hotkeys to change these defaults, could another hot key be pressed to remember those changes for any future videos played within that directory? That way if watching a series the user doesn't need to perform these adjustments again and again.

I actually like the smoothing effect that debanding on high has.

One observation though, for some anime* reducing ringing and reducing halos thingies can degrade seriously the gradients and the overall quality of the image.

Are you watching close to a large low resolution display?



Debanding high/high? Thin edges 8.0? Sharpen edges 4.0? Dithering off?

I watch mostly anime and I would never use anything like that and strongly recommend no one use them unless testing for themselves. Definitely settings that should not be recommended generally.
Those settings give off a sensation of higher quality / resolution without adding color noise, or creating what I call false texturing.

The idea for anime is that some color portions are supposed to be smooth, not have a certain color noise texture. I want to erase that texture and be left with very smooth gradients on full color areas.

Dithering is a cause of [false texture]. It adds a texture that is not supposed to be there. And because madVR has a high bit depth, I am able to use no dithering, otherwise it would look really awful. Testing through many settings, for Dithering to work nicely on off, one has to select 10 bit in Devices -> Properties.

Then again, some people might expect color texture instead of smooth color gradient areas, and as such, might not fully like these settings.

Observation: Not all anime look their best on these settings, since some anime intentionally have a texture, that if erased, the entire thing looks awkward, this type of setting works best with most anime, not all.

All this said I have no idea how anyone can bear having any of the two dithering sub-options enabled so maybe you could try vanilla ED2 with both of these pesky things disabled as one makes the noise dance around on top of the picture and the other creates very faint color fringing
I will keep testing, It's a pretty nice hobby

One thing though, when testing all dithering features, I still can't escape the new texture created thingy (?)

I do wonder why we would need dithering at 10 or even 8 bit.

It's easily visible on what dithering brings to the table on less than 8 bit processing, but it's unclear on what the advantages are on more than 8 bit processing. If someone wants to post comparation images that can show a visible advantage, I'm very curious. When doing this, also have activated debanding on high, since that alleviates all other problems that ditehring was supposed to.

If you're aware of limitations on certain content with reducing ringing please upload before and after screenshots or a sample, thanks. The halo reduction as stated in the options isn't recommended for anime.

it is not hard to show why dithering is needed.

dithering
no dithering

it is needed for correct color anyway.
