This userscript adds a button to YouTube videos that allows you to revert from PAL to NTSC playback.
The script modifies YouTube's interface by adding a button labeled Revert PAL to NTSC. Clicking this button toggles between PAL and NTSC playback modes. Playback is set at approximately 0.95904095904x speed with pitch correction disabled, mimicking NTSC standards.
NOTE: This userscript is designed to revert content that has been PAL-pitched from the original NTSC format to its original NTSC playback speed. It may not work as intended if the content has not been PAL-pitched.
