madVR - high quality video renderer (GPU assisted)

Try checking a few of the image enhancements at the same time and set them to a high value. I would also expect to see an immediate change, but it can be hard for your brain to adjust by simply changing a setting and looking at the screen for an immediate change. It is often better to watch some familiar content for a period of time, and then change the settings once more. Watching the display for an extended period makes it easier to determine if something has changed from the settings you were accustomed to previously. Your brain sometimes needs time to adjust. Display or color calibration can be like that.

highlight recovery strength in HDR -> SDR tone mapping is another example of this. Some people enable it and switch from low to are you nuts!? during playback and claim to see no difference. If you watched some content for a prolonged period of time, the difference between these two values can be dramatic.

I use two players at the same time one with default render and the other with madvr, in pc i can see the diference but in the projector ther e is no diference at all, i will try to connect the htpc to the monitor and see what happens

Depends on the scene a lot with this one. Just find one with clouds and change this value.. And anyone claiming they can't see a difference has medical issues. First scene in World of HDR highlights the difference rather well here.
Sometimes though people just have no idea on what to look for and are also looking at blown out over sharpened displays to begin with..

With image enhancements i see this on my monitor with my pc when i change in pause, but i can't see the diference in my projector with my htpc doing the same

Left one is 4k HDR with madvr in a 1080 display the other the blue ray, if i do the same in the htpc they are shown almost equal except for the color, not the sharpen, maybe the htpc is not doing downscaling?

[ryrynz]

There's a huge difference between those two pictures, The one on the left is considerably sharper.
Look at the rocks.. look at the jagginess of the wires on the left image that run along the roof of that tent.

Ive been battling the Anamorphic mode on madvr for days and still dont understand what im doing wrong....
I upscale all my ripped BDs to 4K through madvr. I use JRiver on my JVC X9900 projector, with an Isco L lens and cineslide.

When I engage Anamorphic mode in madvr (set to default 4/3) the strectch is correct but the sides of the 16:9 window come in closer to a 4:3 window. For the correct stretch size the window sould be the same width as the 16:9 one when the A stretch is activated in madvr. I have the same height with the correct stretch but the width is not to the sides of the 16:9 screen, I need it to be the same width as 16:9 as the lens when engaged stretches the width correctly to the sides of the scope screen.

I hope you guys who use the A stretch on madvr and 4K upscaling can help me...

I have tried a multitude of Window sizing but cant understand how to get this right Im afraid...

Yes i can see it in my pc but doing the same in my htpc I don't see it with the projector, maybe the nvidia card? In the osd can't find if it's appliying the sharpen, left image i what i want to get in my htpc but i change the values and it does nothing

As was said previously, use the OSD (Ctrl-J) to determine that madVR is actually changing things whilst connected to the projector. If that can be seen then it's related to your viewing setup, in which case it would make sense to only change values that provide you a visual benefit. I have not seen this issue before, my assumption is that it's likely your projector that doesn't show the changes in image well.

Internal processing can "undo" much of the benefit of madVR, especially if any scaling is being done.

Also, make sure Focus Assist is completely off, all the options in the focus assist settings page should be off.

Hi Guys,
I was thinkin' that my old GTX 970 was not enought to reproduce 4K HEVC files @60fps but this is not the case.

I've created a new HTPC with NVIDIA RTX 2070, cpu i7 7700T and a new asus mobo pci express 3x. Win 10.

Latest Nvidia drivers. Focus assist deactivated.

Still have massive (very massive)drop frames with those 60fps files ... My queue is always empty ...also with low rendering times.

The attached pictures are taken during reproduction...

MadVR is the latest with V39 beta build installed.

The 60fps files are on an SSD drive.

Some days ago I've tested this also on a Pc of a friend that has a 1070ti and dropping frames with HEVC 60fps files still there ...

Please give some help.

Thank you

In the lav filter image attached to previous post there is: hardware accelerator =none.

Maybe this is the problem?
Maybe I'm not using nvidia hardware hevc decoder?

You need to upload the pictures to an image site, as it takes a long time to get approved on site.

You're probably right. HEVC requires a lot of CPU power to decode directly because of the complexity of the compression algorithms.

[Asmodian]

I agree, a 7700T cannot decode 4K HEVC in real time, using software decoding.

Try changing it to D3D11 or DXV2 (copy-back).

Hi guys, the queue is empty with D3D11 actived!
Look at the images...







I've already tried DXV2 copy back but still have the same amound of droped frames...

If I'm not using the hardware decoder of my RTX 2070 ...how to activate it??

[Warner306]

Set the hardware device to "Automatic (Native)" not the RTX 2070.

It has also been advised to use enable automatic fullscreen exclusive mode with the RTX cards.

[huhn]

did you even check the properties if this is even a HEVC file?

If I remember well at the biginnin' lav decoder was set "automatic native" but the massive drop frames still there.
This evening I'll verify it again

I'll try also FSE but I can't imagine that is this the reason of my empty queue ...

Not checked but ... Billy lin (look at the image) is HEVC for sure.

Can someone of you post a capture of his LAV video decoder panel?
I want to see if your LAV reports something different of mine ...

thanks

It is because the graphics card is choking, others have mentioned issues unless in FSE with the new cards, also I see no mention of HDR on the OSD.

Try HDR passthrough as well before you use the newer HDR options (which you have switched off in Trade for Performance mostly) and work from there, but do what the others have said first.

you can check the file with properties in mpc-hc.

your lav filter setting are showing software decoding and you have a select a hardware decoder so this looks like an incompatible file format.

Checked now. It's HEVC, mkw and HDR file. You can download it there....

I'm pretty sure this is the reason of my problem .... with every option under LAV decoder checked I can't see anything different on: hardware accellation = none.

Any idea to activate it?
Any option under nvidia control panel?
