My own preset shaders that i uses daily to enhance image quality when using MPV , an open source and very customisable media player. The shaders included in this are

1. KrigBilateral by Shiandow
2. Luma Sharpen Hook (basic package only)
3. Adaptive Sharpen 3.SSimSuperRes

You may find these shaders individually at :

1. https://github.com/classicjazz/mpv-config/blob/master/shaders/KrigBilateral.glsl
2. https://github.com/classicjazz/mpv-config/blob/c747aed28d0f811dc84bd5edc4f4feaf19ac8b27/shaders/SSimSuperRes.glsl
3. https://github.com/deus0ww/mpv-conf/blob/feab7ef3d848deb0d77d5f8316c27ac492b0b806/scripts/Shaders.lua

Now you will need to change/add the following line to your MPV's input.conf : CTRL+(number you want to use 0-9) no-osd change-list glsl-shaders set "/shaders/SSimSuperRes.glsl;/shaders/KrigBilateral.glsl;~~/shaders/adaptive-sharpen.glsl"; show-text "SSimSuperRes+KrigBilateral+AdaptiveSharpen"

also you may want to set a number to clear out the shader effects :

CTRL+(number you want to use 0-9) no-osd change-list glsl-shaders clr ""; show-text "GLSL shaders cleared"

alternatively i have included my input.conf file for use, if necessary. You cna put these in the directory C:\Users(USERNAME)\AppData\Roaming\mpv on Windows 10. For Linux users you can find it elsewhere,it shouldn't be a problem once you look up MPV's main archive on :https://mpv.io/manual/
