This CrossBilateral mpv shader works very well.

I hope you will port it inside madVR soon!

Could you bring the one-pass AdaptiveSharpen back into madVR?

It uses much less gpu and looks pretty good.

Looks like that's pretty much a verbatim copy of the latest version of the Bilateral chroma scaler I wrote. Well, except for the lines referring to the originals. They could have at least mentioned my name somewhere...

Anyway madshi did say he was interested in the new Bilateral scaler, so with any luck there might be a MadVR version soon.

Hi!

I don't see it mentioned, but ProgDVB recently added madVR support. (according to the topic search) So if anyone who has a PC tuner wants try or test they can do. (There's a free version)

Formerly I had trouble finding a well working free tuner app that had madVR, which beside the lack of the usual quality improvement you can expect from madVR meant that I got fugly aliasing on downscaling thanks to the crappy Nvidia/AMD drivers and EVR.

MadVR support at first was pretty buggy, with crashes and wrong aspect ratio. Now to the only issue that remains is that for some reason it has a low-res OSD, compared to the HD one with EVR.

I don't see anything in the Settings, but I thought I'd ask: is there any way to set the font size of the OSD? The old size was too small, and the new size is too large. I'd like something a little smaller so it fits in the black border area of SD movies on a 1920x1080 display.

Currently there is no way to adjust the font for the OSD.

madshi: while doing some experiments with 3DLUTs and calibration curves, I've noticed that the "disable GPU gamma ramps" option does absolutely nothing if a 3DLUT with calibration curves built-in is loaded. madVR will always load the calibration from the 3DLUT into the GPU gamma ramps, no matter what. I guess in a way that makes sense (if one generates a 3DLUT with calibration information, it's because one wants it to be loaded), but it's very confusing to have a checkbox that does nothing. How about graying out the checkbox when a 3DLUT that contains calibration information is loaded?

(When using a 3DLUT that does not contain calibration curves - e.g. when not using ArgyllCMS collink -a nor -H options - the "disable GPU gamma ramps" option does what it says on the tin.)

even with an 3D LUT loaded that ignored this setting it should still be possible to select.

for example you are creating a new 3D LUT. the 3D LUT will be unloaded automaticly but the new 3D LUT can be created with or with out the gamma ramp depending on the setting selected.

Yes. That's why I suggested graying out the option if a 3DLUT that contains calibration information is loaded. The checkbox is still useful when a 3DLUT that does not contain calibration information is loaded.

(That said, if you ask me, using 3DLUTs without integrated calibration curves is quite error-prone and seems like a very good way to shoot yourself in the foot by accidentally messing up the gamma ramps, but that's just my opinion.)

How does a 3D LUT impact performance? I noticed my render times going up and down sharply while using one.

depends. i had no notable performance issues at 1080p but with UHD a 3D LUT eats my GPU from time to time depending on a lot of settings.

a 3D LUT with SM creates a lot of problem for me. + 100 ms spikes and stuff like that.

the conclusion was that the driver was doing strange things with "rare" colors. nothing has change since this for me. i worked around it with some settings and setting that take 12 ms without a 3D lut.

Hi,My RAM is getting full after playing video say for 1hr.
Got 8GB RAM & at starting of player , it's 25%.
But after 1hr it becomes 95%.
Forwarding ,going into fullscreen or out of full screen takes time like forever.
it's like something is loading into RAM but not releasing.

I'm using
madVR 0.90.20
mpcBE 1.4.6
LAV filter 0.68.1
XYSUb filter 3.1.0.746
Sanear AUdio Renderer

I have this same issue on my GTX 650 running a QHD (2560x1440) monitor under Windows 10. I'm guessing it has to do with insufficient video RAM on the card and moving things back and forth between the card and system RAM, but I'm not certain. I plan to replace it with a GTX 1070 shortly so I haven't spent a lot of time trying to sort it out.

I have a feeling there's more processing involved and when the video content changes (higher bitrate?) that causes a spike in render time. I've seen it go up as much as 15 ms. I hope madshi can go into detail on this.

To alleviate this, I setup a key to toggle debanding. It's usually not a big deal to me if it's off, but it saves performance.

bitrate has nothing to do with this.

the decoding queue would fall first and the rendertime wouldn't spike.

Someone has uploaded a bunch of LG HDR demos and they look amazing!
those that works with madvr are the HDR10 videos
the Dolby Vision clips works but madvr doesnt detect them as HDR and so they look washed out.

Enjoy
https://www.avforums.com/threads/pan...#post-23694482

the rest
https://mega.nz/#F!aBAGBJBb!vGOiLiLo9HT7fBA1qww3-Q

List of the HDR10 videos:
LG_2_DEMO_4K_L_H_01_Daylight.lge
LG_2_DEMO_4K_L_H_02_UHD HDR Tech.lge
LG_2_DEMO_4K_L_H_03_Daylight.lge
LG_2_DEMO_4K_L_H_04_UHD HDR Tech.lge
LG_2_DEMO_4K_L_H_05_Rays of Light.lge
LG_2_DEMO_4K_O_H_3_NASA HDR.lge
LG_2_DEMO_4K_O_H_4_Colors of Journey.lge
LG_2_DEMO_4K_O_H_5_Chess.lge
LG_2_DEMO_4K_O_H_6_Cymatic Jazz.lge
LG_2_DEMO_4K_O_H_7_OLED HDR Tech.lge

rename the videos to "MKV"

On my GTX 650 the render time oscillates / bounces up and down significantly when the 3D LUT is enabled and playback is full screen. When it's in a window not being scaled to 1440p it does not. Hence my blaming RAM. On my R9 380 connected to my TV (FHD) the 3D LUT doesn't change the render times in any appreciable fashion.

Based on what I've seen in store with the Sony HDR demos playing back in HDR and non HDR on an LG 70UH635T the difference isn't as great as the image you posted would make it seem, in fact not even close.
HDR is more realistic sure, provides more depth to the image sure but the Rec.709 picture in no way looks washed out at all.
Typical marketing overdoing it, it's pretty common in the industry.

Pretty OT but yeah, do we even care for HDR at all? 3D kept crapping out and eventually went belly up twice so they figured they'd have to come up with some brand new sales bs but at the end of the day does it even matter to us? My current mVR rig certainly doesn't look washed out hah.

Given the system specs listed below and lack of HDR display, what Nits value should I set for HDR Peal Luminance setting? I would like the image to be as accurate as possible...

it depends on how bright your display can get so there is no answer.

there is no correct way anyway because there is no clear spec on how to compress the dynamic range.

TV are just doing what they want.
