I set it

1080p23, 1080p24, 1080p25, 2160p23, 2160p24, 2160p25, 2160p30, 2160p60

But it even go to 4K60 Hz instead staying 4K59 Hz which what I use default for everything.

As huhn suggested, this may happen because madVR is not sure if the 25fps movie might need deinterlacing or not. If deinterlacing is needed, 50Hz is the best match, but there's no 50Hz option in your list of display modes. Try adding 1080p50.

Not necessarily. IIRC, if both 1080p23 and 2160p23 are listed then madVR will switch to the mode which matches the native video resolution. I'm not sure why a user would want that, though, because madVR is very likely better at upscaling than the TV.

I was thinking a value from 1 (very low) to 5 (very high). This value could be determined based the video format (FourCC) and the bits per pixel. The latter value is not known directly yet. Perhaps LAV Filters could export the bitrate (if known). Otherwise a rough estimate could be made using file size and duration.

Hmmmm... Might make sense. FWIW, the profiles already support "MPEG2", "VC-1" and "h264" as boolean checks. So I think I don't need to include this in such a "quality" value. "bitDepth" is available, too. I don't know the bitrate, and I'm not sure that LAV can export this easily? Is the video bitrate information available to the splitter/decoder? I suppose I could make the file size and duration available, or an estimated bitrate based on the file size vs duration, but I'm not sure how reliable that would be because you could have e.g. a low bitrate MPEG2 video with a PCM audio track.

Thoughts?

Does the OSD (Ctrl+J) still update in that situation, or is it stuck (or even invisible)? Which decoder type are you using (software, native dxva, copyback dxva, cuvid, d3d11) in LAV? Have you tried software decoding?

RCA5 - original - RRN5


RCA and especially RRN definitely needs strength levels lower 1.

Ah yes, agreed on texture detail killing!

Windows 10 16299.15 build MadVR .v0.92.4 Nvidia drivers 387.92 (Titan Xp SLI)

Did it ever work? If so, what did you change? Seems latest Nvidia drivers are troublesome for HDR, so maybe try older drivers.

The deblocking filter definitely helps these videos a lot!

In general I think I'd like it if I could enable chroma deblocking without enabling luma deblocking at all, for videos where the luma channel is fine but the chroma channels need some help. Or do you think that would just be a waste of cycles for something imperceptible? I'd like to think that some deblocking might help the chroma upscaler do a better job.

I'm a bit torn on how to make this available to the user. Of course I could simply split luma and chroma up (for both deblocking and denoising) and make it possible to choose totally different strengths for both and even enable chroma without luma deblocking etc. However, doesn't this make the whole usability worse again? If users quickly want to just deblock the whole video (luma + chroma), they would have to always update both strengths to match. That's currently easier to do. So I'm not sure what I should do.

Thoughts?

Is this a new problem with v0.92.5/6? Or was it always this way when using madVR? If it's a new problem can you please test with exact madVR version introduced this problem? You can download old builds for testing here:

I did a search for "Light Alloy" in this thread and only found one hit. They (LA) claim it works with this software, but on madvr's home page, Light Alloy Player is not listed. There are at least two issues with it, but it may be LA's software. Anyone else use LA here?

Wasn't aware of the "Light Alloy" player. If the player devs want to discuss problems with me, or have their player listed, they're welcome to contact me.

Is there a way to set this to a reference setting ?

No, because HDR videos ask for specific pixels to be rendered to a specific luminance value, and that is only possible for madVR if you tell it the exact peak luminance value of your display. Every display is different.

I can only compare it to the 1080p remuxes i have of the same movie, but the difference between mastering makes the task kind of a confounded.

How are you guys setting the hdr to sdr , just eyeballing it?

So far with Luminace compression OFF and nits set at 270, seems as close to the 1080p remux as I can get using these settings alone.

I've usually found that a good HDR movie looks better than the 1080p studio SDR encode, but it's not always the same nits value that gives the HDR movie an overall "comparable" brightness/contrast. It differs from movie to movie. My advice would be to try a couple of HDR movies and trust your eyes in picking a nits value that looks good to your eyes. It might also depends on the ambient light levels. A lower nits value makes images more contrasty/punchy, but if there's a lot of ambient light, shadow detail might get lost.

-because those new settings are upfront in the "processing" tree we can't quite make profiles for them apparently, hopefully I can leave "compression artifacts" at 1 and call it a day?

Why can't you make profiles? Works just fine for me.

The PotPlayer dev just fixed a probably related bug today, so this problem might be fixed by the next PotPlayer version.

Cause when I play a Dolby Vision TS file nothing indicates that this is even Dolby Vision. Then when I convert it via MKVToolNix Dolby Vision doesnt work anymore but the MPC info is more or less the same.

Is there a way to show if DV is active(even though not working via MPC)?

What do you mean with "Dolby Vision doesn't work, anymore"? Does it ever work? How?

Actually, it might be possible. Dolby Vision consists of an additional video stream/layer, and additional metadata. What madVR could in theory do is:

1) madVR could make use of the additional video layer + additional metadata to move the video up from 10bit to 12bit+. This should produce a benefit for every display, regardless of whether it supports Dolby Vision or not, or whether it even supports HDR or not.

2) madVR could behave like any official Dolby Vision source device and send the video to a Dolby Vision compatible display, including all the dynamic metadata etc. This is theoretically possible, with any HDMI 1.4+ GPU, as long as it supports a perfect RGB 8bit "passthrough", where all bits stay untouched by the GPU driver (and Windows). The reason this would work (if perfect passthrough is available) is that the dynamic Dolby metadata is actually encoded into the image pixels, as a sort of watermark. So it doesn't require any specific HDMI version, and it even works if there's an AVR in the middle which doesn't support Dolby Vision (as long as the AVR keeps the watermarked pixels untouched).

The whole Dolby Vision processing is very complicated, but I would be willing to at least give 1) a try, maybe even 2), but it would require me to get access to the decoded Dolby Vision enhancement layer, plus to all the added Dolby metadata information contained in the base + enhancement layers.

So basically for any of this to work, first the splitter + decoder would have to be enhanced to deliver the Dolby Vision information to madVR. Then I could look into how to process it all.
