I went through all of the instructions and double-checked the mpv folder to ensure that the correct files were there, yet whenever I try to move between the ABC presets I hear the key error noise in MacOS (meaning the command wasn't registered) and nothing happens.
I am not sure what I am doing wrong here, but I can at least confirm there is some kind of upscaling happening in IINA because it looks sharper than the same file playing in VLC.
Any advice would be greatly appreciated. Thanks!
