Recommended video player
Here are some basic setup methods for different video player and operating system. For further improving visual quality I recommend reading my extended guide after that.
With mpv on Windows 10 (or newer)
Create a new folder (e.g. “mpv”) for mpv where you want. Download mpv (older CPUs) or mpv (newer CPUs) and extract all the files to your mpv folder. Download these two “.conf” files (mpv.conf + input.conf) and copy them inside your mpv folder. There is an “installer” folder as well an an “updater.bat”, first run the “mpv-install.bat” inside “installer” as an administrator and then the “updater.bat” as an administrator. Now it should be possible for you to select “mpv” in the “Default apps” menu on Windows as your default app for video/music player. For some quality of life improvements, there are a few scripts like autoload.lua you can add. Just create a folder with the name “scripts” inside your mpv folder and copy the .lua files in there.
Your mpv folder should look like this:
With mpv on Linux (Example: Manjaro)
Download these two “.conf” files (mpv.conf + input.conf) first. Then download “mpv Media Player” with your Pacman-Manager. Navigate to “~/.config/” and create a folder with the name “mpv”. Copy the two “.conf” files inside that mpv folder.
Other video players
Almost every libmpv based video player (IINA, Celluloid, …) supports mpv config files. The setup might work the same as with mpv or you have to activate a special setting in the menu. I recommend reading the documentation for them.
Note: My “input.conf” overwrites and adds some bindings.
