This is a tool I made to fix syncing issues for that video you find on YouTube. Simply paste in the URL and hit “Load Video” and then you can adjust the audio. The buttons below the video control only the audio. Note that when you skip to a different part in the video you’ll have to adjust the audio again. This tool is meant to adjust clips to watch here, it does not actually modify the existing clip and cannot be saved for later viewing. Enjoy!
