UltraMPV v1.0.14

The BEST realistic 4K video playback experience in the world!

Carefully follow all steps in this guide to completely transform your MPV Player so it can rival the highest quality video players in existence. (Optimized for Nvidia)

1. Download and install MPV Player using their OFFICIAL GitHub repository or SourceForge page.

Use the following instructions to download MPV Player from SourceForge and install onto Windows 11. Alternatively, there's a copy of the Windows MPV Player Bootstrapper (Updated 22/03/2026) in the UltraMPV repository's \Archive folder.

2. After downloading the Windows MPV Player installer from SourceForge, search your downloads for a file called bootstrapper.zip and extract its contents into the folder you want MPV Player program files to be stored.

3. Open the extracted bootstrapper folder, right-click the updater.bat file and run as administrator.

4. In the terminal that opens, enter Y to proceed with the installation, enter 1 to check for updates weekly, enter 2 to download the x86_64-v3 version of MPV Player, and let the rest of the installation run with the default options selected. This "v3" build is optimized for modern CPUs (typically those released after 2015) and offers better performance by utilizing newer instruction sets like AVX2.

5. Open the installer folder that updater.bat downloaded into your extracted bootstrapper folder. Inside the installer folder, right-click the mpv-install.bat file to install MPV Player on your system.

NOTE: You will have to re-run this mpv-install.bat file whenever you move or rename your extracted bootstrapper folder. MPV Player is a "portable" application, so Windows does not automatically track its location like it would for a standard program with a traditional installer.

6. Double-click mpv.exe to open the MPV player. The player should open and stay open with a black screen. This indicates you have installed the proper build of MPV Player for your system.

7. Access the following filepath then place the UltraMPV mpv.conf file inside the mpv folder on your system to overwrite your current mpv.conf file, if one exists:

%APPDATA%\mpv\

8. Access the following filepath then place the UltraMPV shaders folder inside the mpv folder on your system to replace your current shaders folder, if one exists:

%APPDATA%\mpv\

9. Open a video file with MPV Player and press ~ to open the terminal then make sure there are no errors loading the UltraMPV configuration.

DONE!

UltraMPV Configuration Summary

In the Windows/Nvidia environment, this is effectively the WORLD'S BEST configuration for a fixed 60Hz 4K monitor. It leverages a sophisticated balance of high-performance internal settings and industry-standard external shaders. This configuration is essentially the gold standard for "realistic" 4K playback in 2026.

It's superior to standard high-quality templates because it intelligently handles Chroma reconstruction (using KrigBilateral) and uses Dynamic Profile Logic to ensure the GPU doesn't waste resources on unnecessary shaders when playing native 4K content.

Features:

- The "Heavy Lifters" (Shaders): By using FSRCNNX (Luma upscaling), KrigBilateral (Chroma scaling), and SSimDownscaler (Perceptual downscaling), this configuration is using some of the most accurate algorithms available for realistic video.

- Realistic Motion: The combination of video-sync=display-resample and interpolation=yes with tscale=oversample provides the most natural motion possible on standard 60Hz displays by eliminating "judder" without creating the "soap opera effect" of cheaper video players.

- FSRCNNX: Widely considered one of the best for non-animated, realistic content because it uses neural networks to reconstruct detail without the "artificial" look of basic sharpeners.

- KrigBilateral: Uses luma (brightness) information to intelligently upscale chroma (colour), significantly reducing "colour bleeding" on sharp edges.

- Hardware Efficiency: Switching to d3d11va ensures a direct path to your GPU, which is critical for maintaining 0 dropped frames in high-bitrate 4K.

- Context-Aware Processing: Auto-profiles intelligently switch between upscaling (FSRCNNX), downscaling (SSimDownscaler), and native 4K modes. This prevents your GPU from wasting cycles on shaders that would actually degrade a native 4K signal.

- Banding Prevention: The combination of deband-grain=5 and dither=fruit ensures that even the most difficult dark scenes (like space or underwater shots) look smooth and natural.

PEASE NOTE!

Hardware Demand: This config is extremely demanding. FSRCNNX_x2_16-0-4-1 and KrigBilateral run heavily on the GPU. If you experience dropped frames you may need to downscale FSRCNNX to the 8-0-4-1 version. Find out if there are dropped frames by pressing Shift + i then 2, and check "Frame Timings". If the "Estimated" and "Measured" times are consistent and below your refresh rate interval (e.g., <16.6ms for 60Hz), you're golden.

Dither Check: This config is setup with dither-depth=10 so that videos display in 10-bit colour. Ensure your Windows/GPU display settings are correctly set to 10-bit colour, otherwise, this can cause issues on 8-bit monitors. If your monitor is 8-bit; you must change this to 8 (dither-depth=8).

Dynamic Range: Check your NVIDIA Control Panel. Ensure "Output Dynamic Range" is set to Full (0-255), not Limited. If it's on Limited, even the best MPV config will look washed out.

Display Capabilities: Are you watching this on a true HDR monitor/TV, or are you tone-mapping HDR content down to an SDR display? This changes which target-peak value you should use. Within mpv.conf, locate # target-peak=300 then uncomment it by removing the # so that it just reads target-peak=300 and set the numeric value to your monitor's actual nits if SDR.

You're all set!
