Most video creators and some professional Youtubers record audio and video separately. The video is recorded with cameras such as DSLR and a high-end microphone. The primary reason is that most of the video recorders are not equipped with a quality microphone. So once the recording is complete, the editor needs to sync audio and video, which is a big job.
But then there are ways to achieve the perfect sync. In this post, you will learn how you can sync audio and video on Windows 10. These tools will allow you to sync them by adjusting or by changing the speed manually.
Since it offers a non-linear timeline, you can place the audio below the video and sync it. You will have to match the audio and video waveforms to ensure they do not sound like an echo or lag to each other. After that, you can export the video in any format this audio-video sync software supports.
- A non-linear overlapping timeline allows you to sync multiple audio and video
- Free video speed editor
- Editing tools help you remove unnecessary parts
- The easy-to-use interface even for beginners
- Exquisite video effects which include background music, text, transitions
- Create transcripts with Speech & Text converter
- Add voiceover to video
This editor is perfect for syncing audio and video on Windows PC. If you need helpful audio video sync software, don't miss this one. Click on the button to download it.
How to Sync Audio with Video on Windows:
Follow these steps to sync audio and video, and follow the method which works best for you.
Step 1. Open EaseUS Video Editor, and then drag and drop the audio-video file into the media section. You can double-click to preview both of them.
Step 2. Click on the plus icon on the video to add to the timeline. Then click on the plus icon of the audio to add it to the timeline. Since we need to sync, make sure that you do not edit.
Step 3. There are two ways to sync audio and video files. You can either change speed or drag them manually to align them.
Speed up or Slow down: If your audio lags the vide or is ahead of the video audio, then you can choose to speed up or slow down. The same can be applied to video. Be aware that changing the speed also effects how the audio may sound like, so only use this method if it works for you.
Drag Audio Track: The second method is more effective and works for all cases. Here you need to align the waveforms of both audio and video together. So, they are perfectly lined up, and there is no echo. So once the audio and video are on the timeline, make sure to zoom them to the maximum, so the waveforms are visible.
Then drag the audio and try to match it with the waveform. Once you are sure, play it. If it does not sound right, repeat the process. Once done, you are ready to export.
Step 4. Lastly, you can export the file into the format you need. Click on the export button, and choose according to your need.
On Mac, you can fix the audio delay using two software—iMovie and VLC. While the former comes preinstalled, you can install them later if you find it more comfortable.
How to Sync Audio and Video in iMovie
Mac users get iMovie as bonus software that is available for free. It offers features such as trimming, voice-over, transitions, effects, and more. You can also edit 360-degree video, multi-camera, and creator trailers.
- Video Editing with automatic audio sync
- Support Green Screen Editing
- Add effects, increase volume and create trailers
- Split clips, detach audio, adjust audio levels, fade in-out effects, and transitions
There is no way to sync audio and video automatically on Mac. If you have audio from an external source, you need to manually sync as we did for EaseUS Video Editor.
Step 1. Launch iMovie, and then drag and drop the file into the media section. You can drop both into the timeline. Since each video has audio as well, you can use iMovie to match it with the audio.
Step 2. Ensure the play head is at the start, and place both video and audio from the start aligned. Use CMD + to zoom in to the level such that you can see the waveforms for both of them.
Step 3. Next, move the audio to the left or right so the waveform of both audio and video matches with each other. Once done, preview and see if there is a delay or if the audio is playing ahead. Once the alignment is done, you can go along with the next step of editing.
How to Sync Audio and Video in VLC
If you want something simpler, you can use the VLC player without too much video editing. It works on all types of videos.
VLC is not a powerful video editor but rather a player, but it offers many features to fix the video. Besides sync, you can also use it to trim videos, record videos, export videos, find codec information, and more.
- Necessary tools to edit video is available
- Support vast types of media formats
- Convert video into another format
- Fix video with a corrupt header
- Available on all platforms, including Windows and Linux
Step 1. Start playing the video to figure out of the audio is out of place sound slower or faster. You can usually figure out if there is an issue with lip-syncing.
Step 2. If you need to slow down, press the "G" key on the keyboard. If you need to speed up, press the "F" key on the keyboard.
Step 3. The default change in audio when you press once is by 50 milliseconds. You can change it by going to Tools > Effects and Filters and then click on the Synchronization tab. Change the audio-video delay by adjusting the numerical value.

Step 1. Visit the website and upload the video files. Once done, switch to the audio section and upload the audio files.
Step 2. You need to manually adjust the slider to match the audio and the video. Since there are no waveforms available, it may take a while to figure it out. If someone is in the video, all you need to is lip-sync.
Step 3. Lastly, click on "Publish video," and the online service will render the video. You can then download it or share it online. If you make an account, you can edit your video any number of times.
You can use Adobe Premiere Rush on Android and iMovie on the iPhone to sync audio and video seamlessly.

Step 3. To finalize it, make sure to use the waveforms. If they are exactly on top of each other, play them to ensure there is no lag. Done that video and audio are in sync, and you can then edit and export the audio.
