Audio in video clips may be difficult to understand or enjoy if volume levels vary throughout. Normalization is a process that sets your entire audio track to a uniform volume level. Some video editing software comes equipped with normalization capability, but you may need to use separate audio editing or normalization software if yours does not.
1. Load the video clip into your video editing software. Make sure the clip is in your primary editing function, whereas the audio exists in its own track on a multitrack viewer.
2. Extract the audio from the video clip. Copy the track if possible, leaving the original audio in place so you can use its waveform as a timekeeper later.
3. Load the copied audio track into audio editing software or a normalization utility.
4. Execute the normalization function. Consult your audio editing software’s help section or user manual, as the process varies by program.
5. Save the audio track as a new file. Rename the file as something different from the audio remaining in your video editing software‘s multitrack view.
6. Insert the audio file into a new audio track on the original open multritrack session described in Step 1. Align the audio waveform with the original.
7. Delete the original audio track, as you will use the new normalized track for your video clip’s audio.
8. Export or mix down the video file session as per usual. The resulting video clip will contain normalized audio.
