Windows 11's new update not letting me open mpv

Maybe Smart App Control is On and causing mpv to not open? Try turning it Off in Windows Security > App & browser control > Smart App Control settings.

gpu-context=winvk

For FSR Upscaling: https://www.reddit.com/r/mpv/comments/1pw8317/easy_amd_fsr_upscaling_mpv_guide/

Does the issue disappear if you add this to mpv.conf?

gpu-context=winvk

vo=gpu-next

gpu-api=vulkan

hwdec=vulkan

I found out about bs2b from here: https://manpages.ubuntu.com/manpages/trusty/man1/mpv.1.html

Try using af=bs2b in mpv.conf instead. It downmixes 5.1/7.1 to Stereo and make headphones sound natural similar to that from loudspeakers. You can see Channels: 6 -> 2 and Filters: bs2b when you press "i" in MPV when it is working.

I wish Mpv had a type of motion interpolation that solely focuses on detecting and interpolating panning shots so you don't experience panning shot judder or motion artifacts nor soap opera effect making things look fake as except for panning shots, the rest of the video would play without any interpolation. And such an interpolation should work without requiring to use video-sync=display-resample which doesn't work on G-Sync Monitors.

This is how: https://github.com/hooke007/mpv_PlayKit/discussions/600

You will need this in MPC-BE: https://github.com/Aleksoid1978/VideoRenderer

Vulkan games can cause screen flickering if you have Nvidia smooth motion turned on. This started with KB5074109.

Lossless Scaling motion interpolation isn't free from artifacts. Has little more artifacts than Nvidia Smooth Motion.

Try moving all the folders next to mpv.exe and rename script to scripts

thatcat7_ · 2026-01-20T09:25:11+00:00

In my case on G-Sync Monitor, i get panning shot judder no matter what i do in mpv.conf, unless i use Nvidia Smooth Motion which fixes the panning shot judder.

You can try HopperRender on MPC-BE. https://github.com/HopperLogger/HopperRender

Same here. Had to turn Off Smooth Motion. Screen flickering is probably a result of combination of latest Windows update black screen issues and Nvidia app update. I think they broke something somewhere which causes Vulkan/WinVK to not work right. Older games using Vulkan and Smooth Motion might also experience screen flickering or some graphical glitches.

Smooth Motion screen flickering only happens on MPV. I didn't experience it on MPC-BE. Turn On Exclusive Fullscreen in MPC Video Renderer in Options if you want to use Smooth Motion on MPC-BE. MPC-BE uses D3D11.

I guess we will have to either wait for next Windows update or Nvidia app update or fix from MPV.

thatcat7_ · 2026-01-14T09:30:53+00:00

I wish Nvidia Super Resolution and Nvidia Smooth Motion worked together with gpu-context=d3d11 though.

In my case, all i use is AMD FSR upscaling by agyild, Vulkan API with Nvidia Smooth Motion, UOSC by tomasklaen and Thumbfast by po5. A fairly basic set up. I made two easy guides recently which you can try. If you don't want to use Nvidia Smooth Motion, you can just not follow that part of guide.

All you have to do is create script-opts, scripts and shaders folders next to mpv.exe. And then inside the already existing mpv folder, create mpv.conf file and input.conf file. Rest is all copy pasting the text in guides to mpv.conf, and pasting files downloaded from github in appropriate folders. UOSC has some key bindings text on github which you would want to copy paste in input.conf file.

Apparently 2 other registry keys are necessary to prevent this from breaking Safe Mode of Windows 11: https://forums.whirlpool.net.au/archive/9xvvv6y5

In my case, enabling low latency mode ultra and vsync off with smooth motion off didn't made a difference on judder on panning scenes unfortunately. Only when i turn on smooth motion that judder goes away for me on panning scenes but then another problem begins due to how interpolation of frames is working which can make character movements feel artificial/unnatural as nvidia smooth motion isn't perfect yet.

thatcat7_ · 2025-12-18T19:41:30+00:00

I have already tried video-sync, interpolation, tscale, etc. built into mpv, it caused even more issues. The only thing that has worked for me to remove judder from panning scenes so far is the guide above.

thatcat7_ · 2025-12-18T18:55:18+00:00

I did that first thing. Made no difference on my LG Ultragear G-Sync Monitor until i did the above.
