Reduce motion judder?

Uniform is too artifact heavy. Why not to try new tech ? Adaptive with 21 default shader that will switch to 13 (recently improved) on complex scenes. Whats your hardware ? As bonus you can also OC monitor to 72 Hz (x3) / add custom mode 48 Hz (x2 fps)

I rewatched Expanse bluray recently with this override and 72 hz (middle ground between soap and judder like original) and it was amazing

smooth.scene.limits.m1             = 800; //1600
smooth.scene.limits.m2             = 1400; //2800
smooth.scene.limits.scene         = 2000; //4000
analyse.main.levels                 = -1;
analyse.main.penalty.lambda         = 14.0; //10
analyse.main.penalty.plevel         = 1.4; //1.5

yes, framerate does matter if you want perfectly smooth playback.

SVP theoretically CAN smooth out the playback regardless, but:
Non-integer factors for increasing the Framerate are bad because the necessary workload increases a lot while actually producing worse looking frames.
That's why its always better to set it to "Movie x2" (or x3,... whatever your hardware can handle) instead of "fixed 60fps" or "to screen".

So for example; let's say you have a 24fps video and your display is set to 60hz. According to your config, SVP would do the processing like this:
  24fps * 5 / 2 -> 60fps
which is worse than having it set to either 48 fps (24fps *2) or 72 fps (24 fps * 3) because more calculation/artificial frames lead to more blur and artefacts.

48 fps might look A BIT less fluid than 60 fps, but the gain in quality is totally worth it.

to sum it up; you need to set your screen to a multiple refresh rate of your source materials fps. (eg. 24 fps video -> set your display to either 48, 72 or 144 - nothing in between)
Using madVR you can automatically change the refresh rate accordingly when opening a video file. now with SVP set to match the screen, you are "perfectly" set up.

which device can't handle 48fps?

sure, reclock is another possibility but the video playback will be faster by ~4% which is definitely noticeable, even with Pitch correction.
Besides it generally being a bit of a pain in the ass -especially on Windows 10- The bigger issue is that you are limited to a 32 bit toolchain.

only a few of the reasons why I wouldn't recommend Reclock anymore... 48 fps should work on any device, which is almost indistinguishable to 60fps, especially if you aren't used to >72hz.

@dlr5668, do you have an example for a device that can't handle 48 fps?

Are you saying that the display needs to be set at 60Hz and SVP at x2, or does the display needs to be set at x2 file refresh rate as well?

For 24Hz, the frame rate is actually 23.975, so would x2 be 47.95Hz?

Both the screen and the projector can do up to 75Hz. Are there any dangers in overclocking them?

OC'd PJ to 48, 72 and 75hz (for the last 2 the only way to achieve this is with CVT Reduced Blank). Monitor only 48hz.
NVCP does not allow 71.xx, just round numbers.

Tested with the profiles mentioned in post 6.
Still getting judder, can't tell if there is any difference between 60 and 72Hz. Used an exactly 24.0 FPS file, not 23.976.

Judder appears in the same fashion on both displays.
Not sure if it's the displays that are limited, DLP should be the best implementation for smoothness.

to test if the "judder" is related to your display config you can check out this page:

it's very easy to see if your display can handle the framerate

Just close everything else like Browsertabs or Programs that are Ressource-Intensive and/or use your GPU in some way and then press the fullscreen Button in the upper right.
Also Edge and IE are not supported. FF, Chrome or Opera are fine.

If it is completely smooth, it's probably your rendering times that cause the judder. Meaning your GPU/CPU can't handle decoding/processing/rendering of your source file + SVP.
If you see interruptions, your display can't handle the framerate.

Also i saw you did the custom resolution via NVCP... while in theory that should work its probably a good idea to check if the settings madVR calculates for you give a better result.

Your 'Power management mode' in the NV Settings should be 'Adaptive', also try to force VSync: ON for testing purposes - or better create a Profile for your video player (to prevent issues with other programs or games) and leave the VSync setting on Application-controlled.

The Dell is set as primary display, with PJ 2nd, extended displays.
Monitor connected via DVI, PJ via HDMI.
The VGA has an 2.0b HDMI and the PJ has an 2.0a for HDMI port #1 and 1.4a for HDMI port #2 (regular 10m/30ft cable), so I don't think bandwidth is a problem.
Tested both PJ HDMI inputs.

Test UFO seems to require the test be run on the primary display, if the test is run on the 2nd display it will take the refresh rate from the primary.
Tested on FF x64, latest, all add ons disabled.
The Dell ran smoothly on 4 refresh rates: 48, 60, 72, 75.
The Benq ran smoothly on 2 refresh rates 48 and 60. On 72 and 75 there was constant judder.

I ran the video test file again with the refresh rates that were smooth on the respective displays, and judder was still present.

Tested SVP on the displays while they were primary/secondary (while extended). Also disconnected each one to see if it would make any difference with only 1 display.

In madvr OSD, the render time is about 8ms, so under the required vsync.
Also in madvr OSD the screen refresh rate is accurate, with one exception: with the Dell on fullscreen (it says it's 60Hz). To achieve a correct value Full Screen Exclusive needs to be disabled.

When testing SVP with 48Hz the CPU is at 50% and GPU at 40%, with judder present. On 60Hz CPU is at 70% and GPU at 90%.

Updated drivers from 416, to 418 and now to 425.31 (last driver with 3D support). Used DDU.
Tested with vsync on (was set at Use the 3D application setting) and changed PMM to Adaptive (was set at Prefer maximum performance). No difference.
The GPU can do PCIE 16 x3, tested with GPU Z.
Settings in NVCP for PJ are: RGB, Full dynamic range, 8bit color depth. PJ is set to PC signal.
Tested with RGB Limited as well (changed from NVCP and PJ). YCbCR is not available for 72 and 75 Hz.
PJ settings: Brilliant color Off. Tried Cinema (Rec. 709) and Game modes. Keystone Off. Noise Reduction 0. Film Mode On. No overscan. HDMI Audio Off (from Windows, NVCP, PJ).

It does not appear all the time, just in some scenes.
For testing purposes I use Love, Death and Robots episode 2 (Morpheus) 3min:42sec, when the camera pans from right to left.

Downloaded the file. Tested at 72Hz on both displays.
There seems to be some minor judder/artifacts at second 4 (around the main character), and the next second 5 on the left side of the face (around the ear).
The rest is too fast to notice anything wrong, but not very smooth.

Will try as soon as I can get a camera.

So, if I have  59,940 Hz LED TV, I should set  23,976 x 3= 71,928  or  23,976 x5= 119,88 ?
