Poorly synced audio can ruin anyone’s viewing experience, and it is a significant problem for filmmakers when they record video and sound separately. Luckily there are different methods to fix this issue. Here, we will share why the issue occurs in the first place and the ways to sync audio and video in Premiere.

Part 1. Why is Premiere audio out of sync?

One of the common issues that occur after editing the video is that you’ll find the audio to be completely out of sync. Viewers generally find the syncing problem while playing the video on a third-party media player, such as VLC, even though the video works fine on Premiere. There may be a simple solution if you are experiencing audio sync issues with your videos in Adobe Premiere Pro.

When the footage adopts variable frame rates (also known as VFR), this can cause problems for both video and sound components of an editing project. It is because they’re not synced together equally well when using different fps speeds on each individually captured clip (i.e., one @ 25fps while another is set to 50).

Part 2. How to sync audio in Premiere?

The audio and video from two different sources can be easily synced with Premiere Pro’s merge clips function. This process restructures the way in which you’ll have to sync your recordings, sometimes called a double-system recording. It is called that because they take place separately for both audio tracks and visually captured footage on screen or camera feeds into one clip together at once instead of having each separate file.

Here’s how you can sync audio on Adobe Premiere with the merge clips utility automatically:

  • Open Adobe Premiere Pro on your PC, and select both the audio and video you wish to sync in the Panel section.
  • Now, right-click on one of the added files, and choose the Merge Clips option.
  • Once you see a new pop-up box, you’ll need to pick a synchronize point. There, select Audio, and rename the clip before clicking on OK.
  • After the previous step, a new file will be created with the external audio wholly synchronized.
  • Lastly, add the external audio into the time and mute the internal file. This way, the outer audio channel will become the primary one, and it will be in sync with the video.

Not only does it work effortlessly on low-end systems(Windows & Mac), but it also offers two unique ways to solve the audio out-of-sync issue. Additionally, it provides the following feature that makes the whole video editing experience worth your while:
