You can change the prescaler to "SuperXbr + SSIM" to achieve that.

In what way is MPV's debanding filter better than MPDN's?

I can't find it:

It's not in the list of all available scalers either.

It's working very well for me in games, while MPDN's deband filter often misses quite some banding in videos compared to madVR. So I thought it might not hurt to have the option to try it.

Btw: Now that super-xbr has far less problems with ringing, it might make sense to add it also as a chroma scaler?

Does anyone know how to launch MPDN from Firefox or Chrome with streaming websites like YouTube?

No, you'd have to add it; if you press "modify list" you can add whatever prescaler you want, which can be as complicated as you like. Since there are increasingly more options it's not really doable to add every single possible method, but I'm always open to better options to put in the default list.

Well, the method is quite simple so I can give it a try. I might try to improve a bit on the method. FWIW I currently see the biggest banding problems when the source is pretty much 'broken', MadVR might be a bit more aggressive in those cases, but in exchange MPDN's method can be used at pretty much full strength without completely obliterating the image.

I'd have to see if that's possible, but for now I'd rather focus on the new reconstructive Bilateral method, which seems rather promising (still need some kind of 'limiter' to prevent artefacts, but other than that the quality is impressive).

I can add SSIM downscaler there, but then SuperRes isn't used at all according to OSD and it's still downscaled with MPDN internal downscaler.

I think this would definitely make sense, since even "HQ" sources often suffer severe banding.
When you set the threshold of your deband filter to a very high value, this kind of banding isn't reduced as much as with madVR deband filter, but the image gets a softer look in general too.

Looking forward to it.
With cartoons, there are currently often errors which are still easy to spot.

I use my laptop/ultrabook very often and sometimes I watch some videos.
Could you share a preset for the Intel HD 530 integrated GPU?

The OSD system might be having some trouble (making it more failproof has been on my todo list for a while) or something is wrong. As far as I can tell the this script should do what you want.

That goes both ways by the way, if you know where to look 'non-reconstructive' methods cause errors that are quite easy to spot as well . One of the easiest to spot is chroma bleeding, but sometimes it's simply loss of detail.

Oops, mea culpa. I totally didn't consider that a script chain can be added as a prescaler option.
Works well and OSD reports it correctly.

Agreed. However, imho such kind of errors is less obtrusive than e.g. bright colored dots between areas of different color, like in cartoons.

Those kinds of artefacts should have stopped mostly with the new version (1.26.2), if not then something is wrong. The remaining artefacts are mostly colour not following edges correctly (usually when there's a dark edge next to a red area).

Yep, that describes it well.

so the debanding algo is changed now?

in the past it was powerful but it could easily remove a huge deal of details unlike madVR f3kd based deband filter.

You might've remembered it the wrong way around.

i did the test my self and posted it here so now. it was at the time the deband filter was still in part of madVR that some time ago! i can search for the post or at least the disc if you like.

I can't remember the earliest implementation of the filter but it's been like this for a long time i.e. preserves more details but not as strong.

found the post.

http://forum.doom9.org/showpost.php?...ostcount=30693

it extremely terrible in motion.

i can cut a sample later but this will take time i don't even know which season this was.

That does seem to be an earlier implementation of the algorithm.

Might want to give it another try with the new version on default settings. Although that image looks like it could be 'broken' in the sense that you have to choose between representing the source accurately, or removing the banding.

got this crash after first time starting with a complete reset of all setting.

Code:
TITLE: SharpDX Error
------------------------------

An unexpected error 'SharpDX.SharpDXException' has occurred.

------------------------------
ADDITIONAL INFORMATION:

HRESULT: [0x887A0005], Module: [SharpDX.DXGI], ApiCode: [DXGI_ERROR_DEVICE_REMOVED/DeviceRemoved], Message: The GPU device instance has been suspended. Use GetDeviceRemovedReason to determine the appropriate action.
 (SharpDX)

------------------------------
BUTTONS:

&Abort
------------------------------
it was most likely running out of vram still this is no reason to crash i guess.

yes it is clearly changed.
and it doesn't harm the truck anymore.

this is with 1.0

MPDN's deband with a very high strength looks a bit like a deblocking filter. I notice this when e.g. watching a news video, the face of the newsspeaker becomes a bit too blurry.

FYI I think the 'power' setting doesn't really do anything at the moment. Should probably fix that at some point.
