How to perfectly sync separately recorded audio and video with Adobe Premiere Pro and Audition

You'll get the highest audio quality in your videos if you use a dedicated microphone instead of the camera's built-in mic. This video shows you how to use Adobe Audition to edit your audio to perfectly align with your video in Premiere Pro or any other video application.

Even though Premiere Pro and some other video-editing software offer a synchronize feature, it doesn't work perfectly. This happens when your separately recorded audio is off by as little as 1/4 of a frame (at any framerate).

Quick overview

The fix is to delete a tiny amount of audio from the beginning of your separate audio track. I set Adobe Audition to snap to frames and my timecode to display in 96 frames per second (FPS) for my 24 FPS video. Set yours to 4 × video FPS. So 30 FPS video would require 120 FPS audio-editing.

Then select and delete the right number of frames from the beginning of the audio. 1 frame of audio would be 1/4 frame of video, 2 frames would be 1/2 a frame, and 3 frames would be 3/4 a video frame.

Resave the audio track and go back to the video app. You should see your audio perfectly aligned.

If you need even more aligning power, subdivide more (such at 8 × video FPS) or into odd steps (like 5 × video FPS for 1/5-frame adjustments).

This is how I edit all of my videos with separately recorded audio.

Very informative video. I happen to be running into the same sync issues under the same recording scenario. The problem i run into is the audio may seem synced at the beginning of the sequence, but twenty minutes down the timeline it’s way off. Will this technique that you used also fix that?

Would love your thoughts, please comment.x
