For some reason, Jinc AR is showing up as Lanczos 3AR in image upscaling.

can you make a screen from the OSD?

the additional information from that screen should help in reproducing the issue.

Are saying that Plasma TV's can produce HDR effect fully???

It looks to me that 2nd picture lost details in the shadows (look below the red tent), and also lost details in highlights (look at the orange blinker of the truck). This is the complete opposite of what high dynamic range should do (at least corresponding to the term as it is used in photography).

The first image just looks washed out though. It may cause more details to be visible, but is that really what one should be seeing? If a blinker is on, can you really see its structure, or is the light just masking that in real life?

just to be sure you are scaling 1920x800 to 1920x1080p right?

if this is the case i will try to reproduce this later.

I'm not sure if this had been reported already, but I'm having strange issues with SSIM downscaling combined with various other settings. It interacts badly with NNEDI3 image doubling and SuperRes. Here are some combinations:

Doubling(luma)+2DSSIM(noLL AND-OR noAB)
or
Doubling(luma)+2DSSIM(noLL AND-OR noAB)+SuperRes


Doubling(luma)+2DSSIM(LL+AB)


Doubling(luma+chroma)+2DSSIM(LL+AB)
or
Doubling(luma+chroma)+2DSSIM(LL+AB)+SuperRes


Doubling(luma)+2DSSIM(LL+AB)+SuperRes


Doubling(luma)+2DSSIM(LL+AB)+SuperRes(AB25)


Doubling(luma)+2DSSIM(LL+AB)+SuperRes(AB75)


Doubling(luma)+2DSSIM(LL+AB)+SuperRes(AB100)


Doubling(luma)+2DSSIM(LL+AB)+SuperRes(AB150)



Also, I have a European ST60 and it seems that 10bit works in FullRGB range in all refresh rates.

Is 2x Supersampling in Image Doubling better than the standard Doubling? I can't see any difference, I got a 2160P TV And I use doubling to upscale movies to UHD.

Supersampling would be 2160p -> 4320p -> 2160p. If the source is 1080p, then you are image doubling (1080p -> 2160p).

Yeah... I'm just playing 1080p content here. It works fine on 720p content and lower. Not sure if it's supposed to be upscaling anything on 1080p tbh.

Anyway, I created some HDR screenshot videos on the Blu-Ray.com forum for us to try:

some kind of Relative Colorimetric but not exactly.

it is ycms, you can probably dig the thread.

...no answer means there is no answer, or it is so common knowledge that it is not worth answering... (in this case it might be the same…).
So, I would like to pinpoint this : there is no such option at the time being, right?
I’m surprised, since there is a lot of magic going on, like up- or down-scaling, on the fly audio delaying, positioning of subs horizontally/vertically…. So, an option to change on the fly (via keyboard keys) the position of subtitles seemed to me somehow “expectable”.
Is there a chance for such a feature?

Another feature request (maybe it is already there and I just could not find it) :
It would be good to have a keyboard command to toggle between 3D and 2D representation of a movie…
scenario : you have a 3D-MVC-MKV you would like to watch with friends, but do not have enough goggles => you watch it in 2D.
At the time being it seems very complicated to change a setup which was set for 3D, to ignore 3D and play it 2D…

Best Regards

madshi has been quiet lately... Can't wait to see what he's been working on. Hoping for something new worthy of a version bump.

reproduced.

lanczos is used or at least shown in the OSD when the image is only scaled in X or Y direction.

jinc is correctly used with a 1440x1080p 16/9 AR source displayed at 1920x1080p.
there is an additional "image y = jinc" line.

you have set your player to stretch. set it to "touch window from the inside" (name can depend on the player) if you don't want that.

I fixed the seeking problem on my HDR test screenshot videos, if anyone is interested in small (10MB) video HDR test files:
Small HDR Screenshot Test Videos

@madshi,
Is there a way I can see the ST.2086 metadata (max-cll) without you adding it into the info panel?

@nev
If you can add the HEVC metadata (mastering information) to the "LAV Video Decoder" -> "Pin Info [Input]" page this will help me (and others) a lot.

My HDR test videos are very small roughly 10MB for the 5 screenshots inside each video.

Not going to happen. Use actual file analyzers if you want to see their content.

And yet I would rather trust a professionally mastered sample video

When I watch a 24.000 fps movie with "use Direct3D 11 for presentation" enabled render queue and present queue are not full. Present time is unusually high too

With "use Direct3D 11 for presentation" disabled stats is ok.

Can I set a profile auto select rules for 24 fps movies?

THank you, I did not know such programs exist.
Shortly after reading your post, I found a good analyzer called MediaInfo LINK that shows me all the HDR metadata I need.

Downscaling with 2d it shoots up into the 80s. That can't be normal. Like i said, all other doubling scenarios 2d only adds around 2-3ms to what 1d costs, and same goes for downscaling 4k native to 1080p, no trouble at all using 2d, again only adds 2-3ms to what 1d costs.

I can confirm that SSIM 2D has an abnormal performance hit when doubling 1080p.

I have a question regarding the SMPTE 170M primaries management in Madvr.

I have many japanese DVD and from my understanding, japan video industry still used SMPTE 170M primaries for DVD authoring instead of the more recent SMPTE C. If I'm not wrong, Madvr is able to manage SMPTE 170M Primaries if the filename is flagged so.

My issue is that, as I used my DVD and not rip (I have too many), I can't used the flag and so Madvr used SMPTE C primaries automatically. And using the primaries toggle option, SMPTE 170M is not listed as it should be very rare. Is a way to use SMPTE 170M primaries with my dvd without to rip them all (yes, I'm a very old fashioned man, I don't even rip my blu-ray)?

Thank in advance for your help!
