Downloading torrents specially Movie Torrents sometimes leaves you with subtitles which either lag or run ahead, which at times can be very annoying specially a movie in different language such as Japanese (Any Anime fan here ?). Luckily there are simple methods of syncing the subtitles.
sync subtitles in VLC Player is by using the keyboard shortcuts H and G to adjust the delay during playback. Pressing H key will increase the delay by 50 ms ( millisecond) and pressing G will do the opposite.
