Other Available Tools for Syncing Audio and Video

VLC Multimedia Player

When it comes to VLC media player, it reminds us of its powerful ability to play videos in any formats or codecs. VLC player also does great in that it allows users to adjust the audio track in the video. Fixing the audio out of sync with the video just needs the K and J keys on the keyboard while the video is playing. Note that VLC can just fix the sync problem while playing the video. Let’s see how to sync audio and video with it.

i. Load the video into VLC for playing

Pull down “Media” and choose “Open File” from the list to select the file to be played in the VLC. Make sure the video is playing before you forward to the next step.

iii. Tune the delay between the audio and video

Adjust the timing of the sound until it matches the video precisely. You’ll then watch the movie in VLC. What’s bad about this solution is it cannot save changes permanently.

Windows Movie Maker

Windows Movie Maker can help to sync audio and video if the audio is not in the video, or else there is nothing you can do with the delay. In other words, this solution is only available for the video which has a separate audio track.

i. Add un-sync video into Movie Maker

Launch the Windows Movie Maker, drag the video into the panel to see if the audio and video play in sync there.

ii. Drag the audio track

After the video is imported, a timeline for the video track will appear instantly. Press “Add Music” to add the audio track to the video. There is also a timeline for the audio. Go to find the point when the audio becomes unsynchronized with video, manually drag the audio track left or right until it sounds synchronous with the video.
