How to Sync Audio and Video: Top Easy Ways in 2024

Watching a video and the audio is out of sync? Don’t worry — this problem is easy to fix. If you’re wondering how to sync audio and video on your Mac computer or Windows PC, wonder no more. We’ll explain some possible reasons for desynchronization, take you through some handy syncing tips, and show you the easiest ways to sync audio and video, including using the best video player for Mac.

Why Audio and Video synchronization Matters for Your Content

Nobody wants to watch a streaming movie, show, or other content where the audio and video are out of sync. This is particularly the case for promotional or instructional videos, where the audio describes how to perform each step, as it is displayed on the screen. If the audio does not reflect what’s happening on screen at the correct time, the instructional video may be useless.

This also applies to videos such as adverts or promotional videos. If the audio is out of sync with the video on screen, the message you’re intending to convey will likely not get across to the consumer.

Handy Tips For Syncing Audio and Video

If you’re wondering how to sync audio and video on Mac or Windows, here are just a few tips to help you:

  • Use a reputable program, either a free one like Windows Movie Maker, or a paid option such as Elmedia Player.
  • Make sure you read the instructions for how to use the software to sync audio and video.
  • If you’re not confident syncing files manually, most software usually has an auto-sync setting which will work for some (but not all) files.
  • If opting for a paid video player for Mac or Windows, always try to get a free trial first, to make sure the software suits your needs.

Possible Reasons for Audio and Video Desynchronization

There are several reasons why your audio and video are not in sync. If you recorded your audio on a separate device from your video, you’ll find it’s nearly impossible to get both files perfectly in sync without adjustment. Or it may be that your audio track may have “slipped” due to a delay during filming that has left the audio out of step with the video track. It could be that your tracks are of different durations due to improper encoding or a broken container.

Finally, parts of the video could be corrupted, meaning a player may skip over them while the audio track continues playing as usual. In all these cases, if you’re wondering how to fix audio delay on Mac, you may need to use an editing app to make adjustments.


As you can see, it’s important to ensure your audio and video is in sync, but it isn’t a daunting task doing so. There are plenty of programs and apps out there that can help you sync audio and video tracks, from premium offerings like Elmedia Player and Premiere Pro, to free options like Windows Movie Maker. We hope this article has helped you decide which of these apps best suits your needs and shown you how to sync audio and video streaming using various apps.


The easiest way to sync audio and video for free is to use a free app like Windows Movie Maker. There are also some other apps out there that offer a free trial, helpful if you just want to sync a couple of tracks.

If the audio in your video is delayed, you can use an app such as Elmedia Player to increase or decrease the audio delay so that the audio track syncs with the video track.

If the audio and video on your TV are out of sync, the method to fix this will vary depending on the manufacturer of your TV. This could be caused by a bad connection or broadcast delay, a faulty Blu-ray disc or DVD, or issues with connectivity caused by a home theater system. Here are a few things you could try to fix the issue:

  • Ensure the TV has the latest software (firmware) installed — and bear in mind not all TVs have software that can be updated.
  • Check all cables to ensure they’re connected firmly to the TV.
  • Try playing video from a different source to determine if the source is the issue.
  • If using a home theater system and a digital optical cable, try manually changing the Audio/Video Sync or Audio Delay settings (if possible).
  • If using the TV speakers, try performing a power reset on the TV.

It’s easy to sync videos to a sound on TikTok, and here’s how to do it:

  1. Launch TikTok.
  2. Find a video with the sound you’d like in the background of your video.
  3. At the bottom of the screen, click the sound, then click Use this sound.
  4. Then tap the Upload button and choose the videos you’d like to appear in the montage (the number of videos you’ll need will depend on the sound you chose).
  5. Once you’ve chosen the correct amount of videos, tap Next.
  6. Ensure Sound sync is selected (underneath the video) to line up your videos with the sound.
  7. Tap Next, then make any additional edits you want to.
  8. Tap Next again and you can upload your video as normal.

There are a number of free online tools you can use to easily sync audio and video online, such as Online Converter. Note that these tools are not usually as fast or reliable as professional apps, and if you get stuck, there’s unlikely to be support available.

You can use Elmedia Player to sync audio. If the audio is ahead of the video, you just need to play the selected video and then choose “Audio” > “Increase Audio Delay”. If the audio lags behind the video, click “Audio” > “Decrease Audio Delay”.
