Syncing audio with video is an integral part of video editing for any video creator. But believe me; it's not such a difficult task if you know what to do. The point is IF YOU KNOW WHAT TO DO.

That's why in this brief guide, we'll show you the simplest way to sync audio with video using a fantastic video editor easily. But wait a minute, some of you might be confused about why we even need to sync separate audio & video when a single camera can record both. So let's first answer this simple question.

Part 1: Why Do We Need to Sync Separate Audio & Video?

Creating great video needs extraordinary video graphics, content, and top-notch audio. And you can't expect a single camera to achieve all these goals. That's why all professional video creators use a specialized camera for recording with a separate audio recording device.

You might think it's an exaggeration, but this small change can have massive effects on the quality of your video. Especially the background noise removal effect of separate external microphones.

But the downside of using this method is that after the recording is complete, you must sync these audio and video files. And if you don't do it right, all the effort goes to the drain within a split second. Well, nobody wants to watch a video with an audio lag. Isn't it?

Correctly synching an audio file with a video is easier than you think. You just need to prepare beforehand and use a suitable video editing tool. So considering these factors, let's first see what preparations we need. After that, we'll recommend a top-class video editing tool to achieve this goal in detailed steps. Why are we still waiting? Let's begin our journey.

Part 2: Preparation for Syncing Audio With Video During Recording

You must make some preparations to sync an audio file with a video properly. It's to have a sound spike to match the footage properly with the separate audio file. And it might look disturbing, but even a simple Clap might do the job.

And if you want a professional way, just imagine the clapper board. You must have seen it in the film industry. This clapper board is used not only to mark the shot but also to create a sound spike when it claps. We use this audio spike as a reference to sync the audio files with the video.

Every time you cut your shot, remember to clap on camera again the next time you roll. It's best to clap before you say "Action" or speak so that it's easy to find and sync when editing. But if you forget, you can also clap at the end of the shot before you cut. That is called a Tail Slate!!!

After you've recorded your video like this, the next step is pretty simple. The video editor we recommend is no other than the world's leading tool in the market, Wondershare Filmora. Let's move forward and see how to sync audio with video using Filmora.

Step3Prepare your files

Now, it's time to prepare our files for synchronization. First, drag the video file down to the timeline from the "Import Media" section. After that, drag the audio file in the same way below the video on the panel.

Step4Sync the audio & video files using the audio spike

Now that the video and audio files are on the timeline, you'll have to find the moment you clap your hands. Look at the waveform from the in-camera audio and the independent audio track. At the moment you clap, we'll see a spike.

Bonus Tip: If you can't find the audio spike, zoom the panel to make it easier.

Now take the independent audio clip and align it so that both the spikes match.
