That's what I said and something madshi is already working on as I also think 1 is a bit high for general purpose use.
Thoughts on the new AA sharpener?

Hi!

I always get madvr's "an error occured in the application" when bookmarking in potplayer. Did anyone experience this? (update: it seems to only happen after frame jump back or forward.)

I also can't send the report because it requires an e-mail client which I don't have (I use gmail in the browser) and it doesn't give me other options, such as saving it into a text file or something.

It seems like some of the reports somehow was copied to the clipboard and caught by the clipboard monitor (It took a long while for me to figure out that I have to press ctrl+c):

https://drive.google.com/open?id=0By...m1abTE4U3R3M3M

I actually get three errors. One when bookmarking, one when stopping playback after, and another right after that. (uploaded one occasion of three reports after numbering them in sequence)

Only madshi-clause or santa madshi can save us regarding Dolby Vision. There wont be any other way to play the stuff via software except MPC. Lets pray together

I haven't tried to create a profile for "processing", as so far I've always used them only for the scaling algorithms but... why do you say "we can't quite make profiles for them"? I don't understand. The option is there.

Edit: did a quick test, profiles work perfectly.

It just appears to be still in "test mode" in the NVIDIA API and thus not allowing to save it

Edit 3:
Checked with MadVR 0.9.2.0.3, it is 99% sure a MadVR bug.
On that version I can set pretty much any resolution and it will save it. Going back to 9.2.0.6 gives me the same behavior/error again.
So can you please fix that?
Looks to not exit/still be in "test mode" when you click save, thus giving the error it cannot save the active mode.

I suppose as said as it might seem you may have to use software decoding. I'm not completely sure why it's only a problem with madVR and not with VMR9/EVR, maybe it's the higher GPU load, as nevcairiel suggests. Probably not something we can do anything about.

It looks like it's using both, nvidia and windows hdr, at the same time. Sometimes it works, sometimes colours look washed out.
I've unistalled everything and installed it back again. Not sure what else to do.

Edit- Rolled back to the previous nvidia driver. It's now working. I still need to open and close the player a few times before it displays hdr colours correctly though. It' s a hit and miss for me.
Thanks for the video. I'll have to double check with the latest Nvidia driver. Maybe it got broken again. If it did, I have a good contact to complain to. But it might take a couple of driver revisions before it's fixed again. For now please stick to an older driver.

Not sure, though, why you have to start & close multiple times, that doesn't seem to be the case for the other users. It may help to get back to very old drivers, ideally one directly before the (spring) Creator's Update was officially released. Those driver builds don't support the "HDR and Advanced Color" OS switch yet, and they were the most reliable drivers for HDR for Windows 10.

Alternatively you can do what I've been recommending for many many months now, and use Windows 8.1 instead of Windows 10. But nobody listens to me, obviously.

Yes, lower strength random noise reduction coming in the next build.

RCA has to be pushed a bit to get results on really bad source, but when watching the content in motion I prefer RRN at 1 even though it smothes a bit too much. I concur that a lower RRN setting would be best.
In those screenshots it seems to me that RCA removes more artifacts and less texture than RRN, so it seems better in this case at least?

Maybe you're running an old version of the MadHcCtrl.exe (settings dialog)? The new settings are supposed to be in the "processing -> artifact removal" settings page.

When I was tinkering I realized I now had to decide whether I use NGU Sharp and lower sharpening levels or NGU standard and higher levels. Then whether edge sharpening and enhancing details were worth keeping enabled with an improved Adaptive Sharpen and how they compared to it. I'm tempted to look at all this over the next few days with various content.

This new AS sharpens the edges of shadowing and lots of inner details which the old one didn't, as it focused more on just the stronger lines which made it very nice for anime.

Comparing new AS 0.7 to old 1.0 I'm finding is that I'm not getting the line sharpness I did (would have to boost to 1.0 to achieve this) but minor shadowing edges are quite visually oversharpened.
I'll look at it on some standard content but you'd probably hate me saying this but..

Look here for a quick comparison of the old vs new AdaptiveSharpen on a grainy image, using much too high sharpening values:

old adaptive sharpen - - | - - new adaptive sharpen

You can see that the old algo produced very artificial catoonish results, while the new algo looks much better. The old algo did sharpen edges more than anything else while the new one algo sharpens texture to some extent, but the end results look much better to my eyes.

Also try with this well known ringing test image:

http://madshi.net/small.png

You'll see that the old algo produced visible ringing while the new doesn't. So overall I think the new algo is a noticeable improvements.

Why not both? Because there are already 6 different sharpening type algorithms in madVR and we don't really need any more. We need less.

Thanks! FWIW, in the first image the algo also softens over the white shape on the girl's shoulder, which is not a good thing. Maybe a slightly lower strength of the algo would be better?

The most important thing is image upscaling. So if you can go to NGU Sharp high there, it might be worth using a very cheap chroma algo, e.g. Bicubic75.

FineDehalo works very well with NGU, but madVR RRA + RDH creates undesired artifacts around the edges.
Haha, you guys with your abbreviations! Took me a bit to figure out what you mean. Anyway, revisiting RRA is on my to do list, but it doesn't have highest priority right now. It might help if you can collect a few short images where the artifacts you're seeing are most obvious, so I have something to look at when I find the time to revisit the algo.

The images you just posted don't really convince me. I see that RRA produces slightly different results than FineDehalo, but I don't really notice any ugly artifacts. Do you have some better images maybe? And can you mark the positions where the artifacts are most obvious?

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.

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?

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:

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.

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.

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.

Truth is I haven't got this nasty error message in a very long while

Crossing my fingers for further RCA granularity, from 1 to 12 or more would be great so I could go as low as possible on HD and as high as possible on low-res without making it too soft.

You should see it clearly with a little zoom on all the external edges of Jack shirt (Source / MadVR RRA + RDH / FineDehalo) :



Just using FineDehalo(contra=1.0) here.
The FineDehalo script has not been updated for a long time (http://avisynth.nl/index.php/FineDehalo), but it is very fast and clean (even for HD content). I am sure that you can do better in madVR.
There is also a function to remove 2nd order halos.

Hmm, I don't think I'd be particularly broken up about not having separate strengths for Luma and Chroma. I don't know if my results generalize to other videos, but if chroma generally benefits from a bit more strength than luma you could always use a multiplier internally to set the strength of chroma deblocking (e.g. 1.67x the luma strength). But this would probably need more testing than my subjective opinion on a single set of videos :P

With only 1 strength setting, you could just have checkboxes for luma and chroma that can be toggled independently.

It is a new problem but certainly not caused by MadVR (I already tested older versions) but a side-effect of the work-around that I found for my DTS problem on a handful of discs. (Sorry, I had overlooked that it was one of these discs.)
So please don't spend your time on that but it is always reproducable.

My initial thought would be to make:
[] Enable deblock
Luma Strength <-------->
Chroma Strength <------> [] Lock Chroma

When "Lock Chroma" is selected, chroma slider/number will change relative to luma. So if a user has Luma 1, Chroma 2, then locks Chroma, and then slides luma to 2, chroma will change to 3.
Kind of like Ver Greeneyes multiplier selection only probably more annoying to implement
With Chroma initially being locked by default.
I haven't tested/have no idea if individual settings are worth it, sorry.

Well, I'm using an old version for a long time (2017-01) now and until recently I didn't experienced this. So something's changed.
Edit: After downgrading to v0.91.10 the problem stops happening. (v0.92.3 is also bugged. I had these lying around didn't try other versions)


Note:
I don't use a newer version because of the aforementioned hang on file opening with madVR. (Which is far more likely to happen with newer versions)
Did you see anything useful in the debug logs?

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?
Having the user do the calculations manually would be unfeasible, except for maybe a select few here. Most newcomers already struggle with creating simple resolution based preset scripts.

Hence the idea to move the intelligence and complexity into madvr itself, and provide a single value that can be used as an indicator for video quality.

MediaInfo can show which % of the file is video data. I checked a few files and those were between 75 and 95. So lets assume on average 85% of the file is video. It doesn't need to be super accurate.
Or maybe just subtract audio stream sizes. Those usually have a known (average) bitrate. Subtitles have negligible size.

Could anyone shed some light?

Quick (could be) obvious question - is there a difference on how the scaling and refinements are applied to x265 and x264 content?

When upscaling 1080p content to 4K (using NGU AA Med for chroma and NGU Sharp for Luma), the settings seem to have a very different impact - for instance, superres refinement kills the image on x264, but, has little if no visible difference (yes, I know about the warnings using superres refinement with NGU, but....) on x265.

Maybe its just my set up (using latest Madvr and Lav).

after some testing i found this so far.

RCA is very useful but some more steps between 1 and 4 would be nice. NGU sharp and standard still look pretty bad with files that "need" RCA even with RCA.

RCA softs the image a lot so i tried to compensate it with a sharpener. sharpen edges does nothing when scaling a DVD to UHD while adaptive sharpening is still effective too effective smaller step between 0.0-0.1 would be nice and add grain after sharping would be highly preferred too it is really difficult to use with adaptive sharpening.

RRN is hard to judge i find it useful together with RCA but not much alone.

the codec does matter the image it self does. my blind guess is that the x265 encode is so soft that there is nothing to reconstruct or the other way around.

Yeah, thats kind of where I got to. What had me puzzled is that I've also tested with some very high quality and super sharp x265 content (17gb film file), and superres has, what seems, no or a much lesser effect than when applied to x264.

it should be "the codec doesn't matter the image it self does" i don't know i miss the "n
't" often.
