So, you have downloaded a public domain movie online that comes with subtitles. A pretty neat deal, since the movie is not in your native language. However, there is a slight problem the subtitles are not in sync with the audio. Luckily, there is a tool that you can use to re-synchronize the subtitles without human input. Autosubsync is a utility application that can help you correct both the shift and playing speed of your movie to make sure that the audio and subtitles play at the same time. The app automatically corrects both the shift and speed with a 0.15 seconds synchronization accuracy. It also has a wide video format support through ffmpeg. The app even supports all reasonably encoded SRT files in any language that should work with any language in any audio. With the Autosubsync app, you can make sure that the subtitle can help you understand the movies better rather than a nuisance that takes up your screen.
