If that's really the case then that test is of no value whatsoever.
See for yourself: https://youtu.be/vNb3X1AM6uI?t=96



Note: there is a way, explained in the video, to calibrate the camera move, probably try several times before they get it right..the camera must move with the moving object because motion blur occurs when eyes track/focus the motion object, if you look at the motion object with your peripheral vision you'll see there is no smeared motion blur, but stepped trails or no blur...

Generally what settings are the best for optimizing 4k HDR material regarding quality? Not that it is needed in general ofc
What to select for the sharpest best most brutal result? Super-XBR and SSIM or NGU and Jinc or SSIM or what?

Is DXVA2 image downscaling supposed to be bad? I am using a 1080p display, and jaggies are especially noticeable when 4K content is downscaled.

My C6 can't even interpolate the moving square on the left side without artifacts, It basically breaks apart when it hits the edge, even with dejudder set to 1. Same result when playing it directly to the TV through usb.
https://www.youtube.com/watch?v=TVtoxUohG5E

No artifacts?

something odd going on here with my setup, I cant play this smoothly at all never mind the artefacts, something in my chain isnt playing nice with 24hz.

First I played with with just 2160p23 in display modes, then I added 2160p24, no diference, then I tried added 24hz in CRU, no difference, then I removed them and ran it in 60hz, the all look the same, its stuttery as hell. If I play it using MPC HC using standard EVR renderer though it plays smoothly with no artefacts.

Any idea why my MADVR isnt playing 24hz properly?


EDIT - found the problem, its my crappy RX550 it doesnt have enough power to upscale a 720 video to 2160p using NGU sharp medium, its smooth again in 1080p or or 2160p using lanczos instead, I need to upgrade this, very disapointing.

Have to say though, zero artifacts, mine is set on dejudder 3 and deblur 0

I'm still on vacation so have not been home to mess with 3d. We'll see if I have any time Sunday or not.

Easily how? Because "easily" using 6 bit panel is frankly uninteresting from an home theatre point of view.
Also, would you be so kind as to point out the LCD TV offering 2160 lines of motion resolution?

sony BFI LCDs.
the sony OLED is most likely in the 1080p region for the line testing if not 2160p.

BFI has it's own problem but cinemas use it too.

Can you link an image of that, what GPU card you're using? I'm using Intel iGPU Hd4600 to downscale 4k on 1080p display with DXVA and haven't noticed any jaggy.

DXVA scaling can be very different depending on the GPU.
On my 1050 Ti, upscaling SD to 1080 with DXVA is much sharper than bilinear, but with much more artefacts than madVR's Lanczos or Jinc (I checked the image 'enhancements' are disabled in NVIDIA control panel to be sure).

AFAIK, the motion resolution test that is commonly used is from FPD Bluray and can only measure up to 1080 lines. Those 1080 lines have nothing to do with FHD being 1080 lines vertically, it's just a coincidence because the pattern measures horizontal motion blur and the lines to observe are drawn vertically. This test is, like the whole motion blur thing, largely dependant on perception, different people can state different motion resolution from the same TV

Yes, classic cinema projectors had multiple motion trail and wide area flicker due to the shutter (3x), but most digital projectors don't use shutters except for 3D AFAIK...

Does Hyper-Threading make a difference for madvr ?

madVr is still running on the GPU.

for decoding yes hyper threading is useful-

Possibly a newbie question here but having installed madVR and going into settings, I don't see any of the NNEDI3 options anywhere. Any hints on how to find out what's wrong?

NNEDI3 has been removed in favor of NGU. NGU Anti Aliasing results in an image very similar to NEED3.

Hi. Any idea why, when playing a (PAL) DVD and manually disabling deinterlacing, the 1st number shown for the decoder queue can go unusually low?
Here are screenshots to illustrate: https://drive.google.com/open?id=17H...e_bHJqCSLfU0L1

TSFile_deint_off : this is an SD MPEG2 movie recorded off TV. When disabling deinterlacing, the decode queue stays at 23-24 as usual
DVD_deint_auto : DVD with deinterlacing kept on auto, decode queue is also at 23-24
DVD_deint_off : when disabling deinterlacing, the 1st number of the decode queue stays lower, between 9 and 13

I'm using latest LAV nightly in DXVA2 Copy-back mode. This is happening both with MPC-HC and MediaPortal so I don't think it comes from the player.

@d3rd3vil: super-xbr and NGU are doubling methods, why would you need to use that with a source that's already 4K?
When downscaling I like SSIM2D100. For cases in which my GPU can't handle it I downgrade to SSIM1D100 or Lanczos4

Doubling methods, well but it would still boost even the 4k quality?! So why not use it if its possible Anything stronger besides xbr and NGU? Downgrading is not an option ofc

NNEDI for chroma probably then luma image doubling is probably enough and then Jinc image upscaling.
