Thanks for confirming that, I was thinking about the same thing.

[Thunderbolt8]

is anyone able to tell the difference of what sharpen, crisp, thin edges are doing?

and what exactly "enhance detail" means? is it normal sharpening? or do just some things get sharpened and others dont? on what basis?

How about you read at least 1-2 pages back first?
Madshi's second post one page back covers that.

Edit: looks like madVR ignores the container set AR (which is 16:9) and instead uses the video stream AR (which is 4:3).

I had tried and wasn't able to reproduce the problem. But I tried again and now found that the problem only occurs with "detect black bars" disabled. Should be fixed in this test build. Can you confirm?

Ah, ok, I understand the problem.

In theory the stream could switch between progressive and interlaced all the time, which would mean madVR would have to switch deinterlacing on and off all the time. If I changed refresh rate every time that happens that could be very annoying. So atm madVR only changes refresh rate in very specific situations: 1) When playback starts, if the settings say so. 2) When going fullscreen, if the settings say so. 3) When manually activating video mode deinterlacing.

Not sure whether there are real world videos out there which often switch back and forth between progressive and interlaced?

Software decoding is not affected because it's fast enough to switch madVR into video mode deinterlacing. DXVA takes too long, so at the moment when madVR wants to switch refresh rates, DXVA has not yet told madVR that the video is interlaced.

The issue is fixed with this build.

Ok, will release a new official later today, will take a couple of hours, though.

You can add e.g. "superResRadius=80" to the file name now to force a SuperRes radius of 80.

Did some testing with SuperRes and will still leave it off as it sharpens the image undesirably. It didn't look too good when I was watching 720p content at 1440p. It was too sharp. Disabled and all was back to normal. I guess SuperRes isn't for me.

[MS-DOS]

AngelGraves13, if you tested it with one of the latest two builds then maybe it's because the Radius option was removed and forced to 0.66, which makes it look way too sharp and aliased sometimes. I used it with 1.00 before and it was totally fine to me.

[aufkrawall]

You could try a higher radius like madshi explained above or a lower strength.

I noticed that after playing around with different upscaling refinements, madVR somehow disabled NNEDI3 and used Jinc instead. It couldn't be activated again unless madVR was restarted. Haven't been able to reproduce yet, but there must be a small problem.

I'm mostly watching 1080p blu-rays from my personal collection that I've remuxed to avoid using discs. The content looks fine with Jinc AR for Chroma and Image. SuperRes doesn't make it look better.

[mzso]

There are a bunch of sharpening algorithms now. Is there some writing about it? How do they compare to each other quality wise. Or in what situation do they come handy?
For a long time I used the players sharpencomplex2 shader. Now I started using madVR's adaptivesharpen, though to be honest I don't know if it's the best one (for me).

imho fonts or emblems look too blurry with 1080p -> WQHD without SR. Especially true for fine white fonts.

I'm using madvr to upscale 1080p Bulray remux files to a 4k Display but there is a lot of noise. Any suggested settings to get rid of it?

Then I'll think about whether it's worth spending time on...

To be hones no, I don't have such video files - it was just an imaginary use case and since you say that it's not easy to be implemented I totally agree with your decision not to invest time in it until there is a legit need for it.

I found the post you are refering to. just dont refer to page numbers please, some people have different posts per page settings.

Thanks for the new build madshi!

I'm an AdaptiveSharpen user and I must say I'm really happy with the new sharpen edges option. I'm torn between the two but I think I'll settle on one of them after some tests.

However, there may be a bug in the new build's "upscaling refinement" options.
When choosing SuperRes on its own, the "refine the image after every...."/"refine the image only once...." is greyed out even though it takes effect according to the checked option of the two.
So If I wanted to change that option I have to check one of the other refinement options temporarily so it becomes visible.

Another black screen log for 0.89.15 with unchanged settings from 0.89.13 where there is no black screen with this clip:

fryingpanfail.webm

log here (dunno why the log is HUGE):
http://s000.tinyupload.com/index.php...52747541458473

Damn, I still get stutters after pausing and then resume videos and nothing I've tried or that was recommended made any difference... Its SO annoying.

[djsolidsnake86]

the aspect ration problem finally is gone

the only problem now is the stuttering when going fullscreen with a video with mpchc

If you find a way to reliably reproduce it, let me know.

Asked and answered twice already in the last couple of pages.

There's no denoise algo in madVR. You could try ffdshow raw video processing with some AviSynth noise reduction script. Sorry, can't tell you any more than this. That's a topic for a different thread. In this thread all I can say is: madVR currently doesn't do denoising.

Ah ok.

Let me know what you settle on and for what reasons. Please judge quality and performance separately.

In the next build SuperRes will always only be applied once, because it simply doesn't make sense any other way. SuperRes has no benefit from being applied multiple times.

I think this should be fixed in v0.89.16.

Please create a debug log with 20 seconds worth of stuttering. Afterwards please stop MPC-HC by pressing Alt+F4, then zip and upload the debug log.

I've done a change in v0.89.16 which should hopefully fix this problem.
