You must have noticed that many cameras don't have good video quality. This problem is even more severe on mobile devices. This is the reason why millions of people worldwide record audio separately while capturing videos. Recording audio separately raises a new challenge: "how to sync video with audio?"

Syncing video and audio often becomes a time-consuming task. Though a couple of audio synchronizers are available in the market, many of them take up all of your system's memory. Instead of using such tools to synchronize sound with video, you should prefer highly recommended, affordable, and reliable software that best matches your needs.

This article not only lists some valuable tips for effective audio synchronization but also helps you learn to perform this task on PC and online.

Part 1. Tips for Syncing Video with Audio

The most important things to remember while syncing audio and video include using a clapboard while recording, recording audio on an external microphone and camera, and paying close attention to audio waveforms when editing. A few more things to consider are as follows.

1. Find video and audio files in the media bins.

2. Drag both files on the timeline and place your video file above the audio.

3. Line up audio from your camera and mic by using peaks in the audio wavelength. In the case of using a clapboard, you can line up two audio wavelengths using the peak that a clapboard creates at the start.

4. Drag the audio file manually to align it with the video's audio.

5. Don't forget to play the clip to ensure that the audio and video are synced perfectly. If it needs some improvement, make quick adjustments for better synchronization.

6. Delete the camera audio while keeping the audio from the microphone.

7. Link the video and audio.
