Quick Tip: Press F and G keys to sync audio in VLC
Oct 7, 2009 - 1 Comment
I just found out that with VLC you can use the G and F keys to re-sync the audio track to a playing video that is slightly off. VLC is by far my favorite application to play any videos in, it’s fast, lightweight, cross platform, opens virtually every video format and codec, and is completely free. You can download VLC for Mac here, it’s highly recommended.

Thanks, that’s excellent, so sick of these youtube videos, seems like about half of them are out of sync.
